PREFACE
This document is the 5th of 12 Parts of the official triennial compilation and publication of the adoptions, amendments
and repeal of administrative regulations to California Code of Regulations, Title 24, also referred to as the California Building
Standards Code. Part 5 is known as the California Plumbing Code and incorporates, by adoption, the 2009 edition of the
Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials with the California amend-
ments.
The California Building Standards Code is published in its entirety every three years by order of the California legislature,
with supplements published in intervening years. The California legislature delegated authority to various State agen-
cies, boards, commissions and departments to create building regulations to implement the State's statutes. These build-
ing regulations or standards, have the same force of law, and take effect 180 days after their publication unless other-
wise stipulated. The California Building Standards Code applies to occupancies in the State of California as annotated.
A city, county, or city and county may establish more restrictive building standards reasonably necessary because of local
climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building stan-
dard (s) must be filed with the California Building Standards Commission to become effective and may not be effective
sooner than the effective date of this edition of California Building Standards Code. Local building standards that were
adopted and applicable to previous editions of the California Building Standards Code do not apply to this edition with-
out appropriate adoption and the required filing.
To familiarize yourself with the format of this code, it is suggested that users review the following contents:
• How To Distinguish Model Code Language From California Amendments
• Matrix Adoption Tables

2010 CALIFORNIA PLUMBING CODE
UPC FOREWORD
Not Adopted by The State of California
The advantages of a uniform plumbing code adopted by various local jurisdictions has long been recognized. Disorder in the
industry as a result of widely divergent plumbing practices and the use of many different, often conflicting, plumbing codes
by local jurisdictions influenced the Western Plumbing Officials Association (now the International Association of Plumbing
and Mechanical Officials [lAPMO]) to form a committee of plumbing inspectors, master and journeyman plumbers, and san-
itary and mechanical engineers, assisted by public utility companies and the plumbing industry to create a basic plumbing
document for general use. The product of this effort, the first edition of the Uniform Plumbing Code® (UPC®) was officially
adopted by lAPMO in 1945. The widespread use of this code over the past five decades by jurisdictions throughout the United
States and internationally is testament to its merit.
With the publication of the 2003 Edition of the Uniform Plumbing Code®, another significant milestone was reached. For the
first time in the history of the United States, a plumbing code was developed through a true consensus process. The 2009 edi-
tion represents the most current approaches in the plumbing field and is the second edition developed under the ANSI con-
sensus process. Contributions to the content of the code were made by every segment of the built industry, including such
diverse interests as consumers, enforcing authorities, installers/maintainers, insurance, labor, manufacturers,
research/standards/testing laboratories, special experts, and users.
The UPC is designed to provide consumers with safe and sanitary plumbing systems while, at the same time, allowing lati-
tude for innovation and new technologies. The public at large is encouraged and invited to participate in lAPMO's open con-
sensus code development process. This code is updated every three years. A code development timeline and other relevant
information is available at lAPMO's website at www.iapmo.org.
The Uniform Plumbing Code® is dedicated to all those who, in working to achieve "the ultimate plumbing code," have
unselfishly devoted their time, effort, and personal funds to create and maintain this, the finest plumbing code in existence
today.
The 2009 Uniform Plumbing Code® is supported by the American Society of Sanitary Engineering (ASSE), the Mechanical
Contractors Association of America (MCAA), the Plumbing-Heating-Cooling Contractors National Association (PHCC-NA),
the United Association (UA), and the World Plumbing Council (WPC). The presence of these logos, while reflecting support,
does not imply any ownership of the copyright to the UPC, which is held exclusively by lAPMO. Further, the logos of these
associations indicates the support of IAPMO*s open, consensus process being used to develop lAPMO's codes and standards.

103.2.1.5 Be signed by the permittee or the permit-
tee's authorized agent, who may be required to sub-
mit evidence to indicate such authority.
103.2.1.6 Give such other data and information as may
be requked by the Authority Having Jurisdiction.
103.2.2 Plans and Specifications. Plans, engineering
calculations, diagrams, and other data shall be submitted
in one (1) or more sets with each application for a permit.
The Authority Having Jurisdiction shall be permitted to
require plans, computations, and specifications to be pre-
pared by, and the plumbing designed by, an engineer
and/or architect licensed by the state to practice as such.
Exception: The Authority Having Jurisdiction shall be
permitted to waive the submission of plans, calculations,
or other data if the Authority Having Jurisdiction finds
that the nature of the work applied for is such that
reviewing of plans is not necessary to obtain compliance
within the code.
103.2.3 Information on Plans and Specifications. Plans
and specifications shall be drawn to scale upon substan-
tial paper or cloth and shall be of sufficient clarity to indi-
cate the location, nature, and extent of the work proposed
and show in detail that it will conform to the provisions
of this code and relevant laws, ordinances, rules, and reg-
ulations.
103.3 Permit Issuance.
103.3.1 Issuance. The application, plans, and specifica-
tions and other data filed by an applicant for a permit
shall be reviewed by the Authority Having Jurisdiction.
Such plans shall be permitted to be reviewed by other
departments of this jurisdiction to verify compliance with
applicable laws under their jurisdiction. If the Authority
Having Jurisdiction finds that the work described in an
application for permit and the plans, specifications, and
other data filed therewith conform to the requirements
of the code and other pertinent laws and ordinances, and
that the fees specified in Section 103.4 have been paid,
the Authority Having Jurisdiction shall issue a permit
therefore to the applicant.
When the Authority Having Jurisdiction issues the
permit where plans are required, the Authority Having
Jurisdiction shall endorse in writing or stamp the plans
and specifications "APPROVED." Such approved plans
and specifications shall not be changed, modified, or
altered without authorization from the Authority Having
Jurisdiction, and all work shall be done in accordance
with approved plans.
The Authority Having Jurisdiction shall be permitted
to issue a permit for the construction of a part of a plumb-
ing system before the entire plans and specifications for
the whole system have been submitted or approved, pro-
vided adequate information and detailed statements have
been filed complying with all pertinent requirements of
this code. The holder of such permit shall be permitted to
proceed at the holder's risk without assurance that the
permit for the entire building, structure, or plumbing sys-
tem will be granted.
103.3.2 Retention of Plans. One (I) set of approved
plans, specifications, and computations shall be retained
2010 CALIFORNIA PLUMBING CODE
21
ADMINISTRATION DIVISION II
by the Authority Having Jurisdiction until final approval
of the work covered therein. One (1) set of approved
plans and specifications shall be returned to the appli-
cant, and said set shall be kept on the site of the building
or work at times during which the work authorized
thereby is in progress.
103.3.3 Validity of Permit. The issuance of a permit or
approval of plans and specifications shall not be con-
strued to be a permit for, or an approval of, any violation
of any of the provisions of this code or of any other ordi-
nance of the jurisdiction. No permit presuming to give
authority to violate or cancel the provisions of this code
shall be valid.
The issuance of a permit based upon plans, specifi-
cations, or other data shall not prevent the Authority
Having Jurisdiction from thereafter requiring the correc-
tion of errors in said plans, specifications, and other data
or from preventing building operations being carried on
thereunder when in violation of this code or of other ordi-
nances of this jurisdiction.
103.3.4 Expiration. Every permit issued by the Author-
ity Having Jurisdiction under the provisions of this code
shall expire by limitation and become null and void if the
work authorized by such permit is not commenced within
one-hundred and eighty (180) days from the date of such
permit, or if the work authorized by such permit is sus-
pended or abandoned at any time after the work is com-
menced for a period of one-hundred and eighty (180)
days. Before such work can be recommenced, a new per-
mit shall first be obtained to do so, and the fee therefore
shall be one-half (Vi) the amount required for a new per-
mit for such work, provided no changes have been made
or will be made in the original plans and specifications
for such work, and provided further that such suspen-
sions or abandonment has not exceeded one (1) year.
Any permittee holding an unexpired permit shall be
permitted to apply for an extension of the time within
which work shall be permitted to commence under that
permit when the permittee is unable to commence work
within the time required by this section for good and sat-
isfactory reasons. The Authority Having Jurisdiction
shall be permitted to extend the time for action by the
permittee for a period not exceeding one-hundred and
eighty (180) days upon written request by the permittee
showing that circumstances beyond the control of the
permittee have prevented action from being taken. No
permit shall be extended more than once. In order to
renew action on a permit after expiration, the permittee
shall pay a new fiiU permit fee.
103.3.5 Suspension or Revocation. The Authority Hav-
ing Jurisdiction shall be permitted to, in writing, suspend
or revoke a permit issued under the provisions of this
code whenever the permit is issued in error or on the basis
of incorrect information suppHed or in violation of other
ordinance or regulation of the jurisdiction.
103.4 Fees.

required to be submitted by Section 103.2.2, a plan review
fee shall be paid at the time of submitting plans and spec-
ifications for review.
The plan review fees for plumbing work shall be
determined and adopted by this jurisdiction.
The plan review fees specified in this subsection are
separate fees from the permit fees specified in this sec-
tion and are in addition to the permit fees.
When plans are incomplete or changed so as to
require additional review, a fee shall be charged at the
rate shown in Table 1-1.
103.4.3 Expiration of Plan Review. Applications for
which no permit is issued within one-hundred and eighty
(1 80) days following the date of application shall expu-e by
limitation, plans and other data submitted for review may
thereafter be returned to the applicant or destroyed by the
Authority Having Jurisdiction. The Authority Having
Jurisdiction shall be permitted to exceed the time for action
by the applicant for a period not to exceed one-hundred
and eighty (1 80) days upon request by the applicant show-
ing that circumstances beyond the control of the applicant
have prevented action from being taken. No application
shall be extended more than once. In order to renew action
on an application after expiration, the applicant shall
resubmit plans and pay a new plan review fee.
103.4.4 Investigation Fees: Work Without a Permit.
103.4.4.1 Whenever any work for which a permit is
required by this code has been commenced without
first obtaining said permit, a special investigation shall
be made before a permit may be issued for such work.
103.4.4.2 An investigation fee, in addition to the per-
mit fee, shall be collected whether or not a permit is
then or subsequently issued. The investigation fee
shall be equal to the amount of the permit fee that
would be required by this code if a permit were to be
issued. The payment of such investigation fee shall not
exempt any person from compliance with other pro-
visions of this code, nor from any penalty prescribed
by law.
103.4.5 Fee Refunds.

for expense entailed in the removal or replacement of
material required to permit inspection. When the instal-
lation of a plumbing system is complete, an additional
and final inspection shall be made. Plumbing systems
regulated by this code shall not be connected to the water,
the energy fuel supply, or the sewer system until author-
ized by the Authority Having Jurisdiction.
103.5.1.1 Inspection. No water supply system or
portion thereof shall be covered or concealed until it
first has been tested, inspected, and approved.
103.5.1.2 Scope. New plumbing work and such por-
tions of existing systems as may be affected by new

system, building sewer, private sewage disposal sys-
tem, or part thereof, which is installed, altered, or
repaired, is covered or concealed before being
inspected, tested, and approved as prescribed in this
code, it shall be uncovered for inspection after notice
to uncover the work has been issued to the respon-
sible person by the Authority Having Jurisdiction.
103.5.2 Operation of Plumbing Equipment. The
requirements of this section shall not be considered to
prohibit the operation of any plumbing installed to replace
existing equipment or fixtures serving an occupied por-
tion of the building in the event a request for inspection of
such equipment or fixture has been filed with the Author-
ity Having Jurisdiction not more than seventy-two (72)
hours after such replacement work is completed, and
before any portion of such plumbing system is concealed
by any permanent portion of the building.
103.5.3 Testing of Systems. Plumbing systems shall be
tested and approved as required by this code or the
Authority Having Jurisdiction.
103.5.3.1 Test. Tests shall be conducted in the pres-
ence of the Authority Having Jurisdiction or the
Authority Having Jurisdiction's duly appointed rep-
resentative.
103.5.3.2 Test Waived. No test or inspection shall
be required where a plumbing system, or part thereof,
is set up for exhibition purposes and has no connec-
tion with a water or drainage system.
103.5.3.3 Exceptions. In cases where it would be
impractical to provide the required water or air tests,
or for minor installations and repairs, the Authority
Having Jurisdiction shall be permitted to make such
inspection as deemed advisable in order to be
assured that the work has been performed in accor-
dance with the intent of this code.
103.5.3.4 Tightness. Joints and connections in the
plumbing system shall be gas-tight and water-tight
for the pressures required by test.
103.5.4 Inspection Requests. It shall be the duty of the
person doing the work authorized by a permit to notify the
Authority Having Jurisdiction that such work is ready for
inspection. The Authority Having Jurisdiction shall be per-
mitted to require that every request for inspection be filed
not less than one (1) working day before such inspection is
desired. Such request may be in writing or by telephone, at
the option of the Authority Having Jurisdiction.
It shall be the duty of the person requesting inspec-
fions required by this code to provide access to and
means for proper inspection of such work.
103.5.4.1 Advance Notice. It shall be the duty of the
person doing the work authorized by the permit to
notify the Authority Having Jurisdiction, orally or
in writing, that said work is ready for inspection.
Such notification shall be given not less than twenty-
four (24) hours before the work is to be inspected.
103.5.4.2 Responsibility. It shall be the duty of the
holder of a permit to make sure that the work will

ADMINISTRATION DIVISION II
103.5.5.2 Moved Structures. Parts of the plumbing
systems of any building or part thereof that is moved
from one (1) foundation to another, or from one (1)
location to another, shall be completely tested as pre-
scribed elsewhere in this section for new work,
except that walls or floors need not be removed dur-
ing such test when other equivalent means of inspec-
tion acceptable to the Authority Having Jurisdiction
are provided.
103.5.6 Reinspections. A reinspection fee shall be per-
mitted to be assessed for each inspection or reinspection
when such portion of work for which inspection is called
is not complete or when required corrections have not
been made.
This provision is not to be interpreted as requiring
reinspection fees the first time a job is rejected for fail-
ure to comply with the requirements of this code, but as
controlling the practice of calling for inspections before
the job is ready for inspection or reinspection.
Reinspection fees shall be permitted to be assessed
when the approved plans are not readily available to the
inspector, for failure to provide access on the date for
which the inspection is requested, or for deviating from
plans requiring the approval of the Authority Having
Jurisdiction.
To obtain reinspection, the applicant shall file an
application therefore in writing upon a form furnished
for that purpose and pay the reinspection fee in accor-
dance with Table 1-1.
In instances where reinspection fees have been
assessed, no additional inspection of the work will be
performed until the required fees have been paid.
103.5.6.1 Corrections. Notices of correction or vio-
lation shall be written by the Authority Having Juris-
diction and shall be permitted to be posted at the site
of the work or mailed or delivered to the permittee or
his authorized representative.
Refusal, failure, or neglect to comply with any
such notice or order within ten (10) days of receipt
thereof, shall be considered a violation of this code
and shall be subject to the penalties set forth else-
where in this code for violations.
103.5.6.2 Retesting. If the Authority Having Juris-
diction fmds that the work will not pass the test, nec-
essary corrections shall be made, and the work shall
then be resubmitted for test or inspection,

tion and final test of the plumbing system, a certifi-
cate of approval shall be issued by the Authority
Having Jurisdiction to the permittee on demand.
103.6 Connection Approval.
103.6.1 Energy Connections. No person shall make
connections from a source of energy or fuel to any
plumbing system or equipment regulated by this code
and for which a permit is required until approved by the
Authority Having Jurisdiction.
103.6.2 Other Connections. No person shall make con-
nection from any water-supply line nor shall connect to
any sewer system regulated by this code and for which a
permit is required until approved by the Authority Hav-
ing Jurisdiction.
103.6.3 Temporary Connections. The Authority Having
Jurisdiction shall be permitted to authorize temporary
connection of the plumbing equipment to the source of
energy or fuel for the purpose of testing the equipment.
103.7 Unconstitutional.
103.7.1 If any section, subsection, sentence, clause, or
phrase of this code is, for any reason, held to be uncon-
stitutional, such decision shall not affect the validity of
the remaining portions of this code. The Legislative body
hereby declares that it would have passed this code, and
each section, subsection, sentence, clause, or phrase
thereof, irrespective of the fact that one (1) or more sec-
tions, subsections, sentences, clauses, and phrases are
declared unconstitutional.
103.8 VaUdity.
103.8.1 If any provision of this code, or the application
thereof to any person or circumstance, is held invalid, the
remainder of the code, or the application of such provi-
sion to other persons or circumstances, shall not be
affected thereby.
103.8.2 Wherever in this code reference is made to an
appendix, the provisions in the appendix shall not apply
unless specifically adopted.

connection (See Part II-Figure G.l(n)). [NFPA
54:13.2.15]
511.2.15 Where used in multistory systems, vertical com-
mon vents shall be Type B double- wall and shall be in-
stalled with a hsted vent cap. [NFPA 54:13.2.16]
511.2.16 Offsets in multistory common vent systems
shall be limited to a single offset in each system, and sys-
tems with an offset shall comply with all of the follow-
ing [NFPA 54:13.2.17]:
(1) The offset angle shall not exceed 45 degrees from
vertical.
(2) The horizontal length of the offset shall not exceed
eighteen (18) inches for each inch (1 80 mm/mm) of
common vent diameter of the segment in which the
offset is located.
(3) For the segment of the common vertical vent con-
taining the offset, the common vent capacity listed in
the common venting tables shall be reduced by 20
percent (0.80 x maximum common vent capacity).
(4) A multistory common vent shall not be reduced in
size above the offset.
511.2.17 Where two (2) or more appliances are con-
nected to a vertical vent or chimney, the flow area of the
largest section of vertical vent or chimney shall not ex-
ceed seven (7) times the smallest listed appliance cate-
gorized vent areas, flue collar area, or draft hood outlet
area unless designed in accordance with approved engi-
neering methods. [NFPA 54:13.2.18]
511.2.18 For appliances with more than one (1) input
rate, the minimum vent connector capacity (FAN Min)
determined from the tables shall be less than the lowest
appliance input rating, and the maximum vent connector
capacity (FAN Max or NAT Max) determined from the
table shall exceed the highest appliance input rating.
[NFPA 54:13.2.19]
511.2.19 Listed corrugated metallic chimney liner sys-
tems in masonry chimneys shall be sized by using Tables
5-14 or 5-15 for Type B vents, with the maximum ca-
pacity reduced by 20 percent (0.80 maximum capacity)
and the minimum capacity as shown in Tables 5-14 or 5-
15. Corrugated metallic liner systems installed with
bends or offsets shall have their maximum capacity fur-
ther reduced in accordance with Sections 511.2.5 and
511.2.6. The 20 percent reduction for corrugated metal-
lic chimney liner systems includes an allowance for one
(1) long radius 90 degree turn at the bottom of the liner.
[NFPA 54:13.2.20]
511.2.20 Tables 5-14 and 5-15 shall be used for chim-
neys and vents not exposed to the outdoors below the
roof line. A Type B vent passing through an unventilated
enclosure or chase insulated to a value of not less than R8
shall not be considered to be exposed to the outdoors. Ta-
bles 5-19 and 5-20 shall be used for clay-tile-lined exte-
rior masonry chimneys, provided all of the following
conditions are met [NFPA 54:13.2.22]:
(1) Vent connector is T3^e B double-wall.
(2) One (1) appHance is draft-hood-equipped.
(3) The combined appliance input rating is less than the
maximum capacity given by Table 5-19 (for NAT +

smaller are not reduced by more than one (1) table
size [e.g., twelve (12) inches to ten (10) inches (300
mm to 250 mm) is a one (1) size reduction] and
those exceeding twelve (12) inches (300 mm) in di-
ameter are not reduced exceeding two (2) table sizes
[e.g., twenty-four (24) inch to twenty (20) inch (610
mm to 510 mm) is a two (2) size reduction].
(2) Fan-assisted appliances are common vented with a
draft-hood-equipped appliance.

nector run or within the common vent, provided ALL of
the appropriate tables permit ALL of the desired sizes
and types of pipe, as if they were used for the entire
length of the subject connector or vent. Where single-
wall and Type B double-wall metal pipes are used for
vent connectors within the same venting system, the
common vent must be sized using Tables 5-15 or 5-17 as
appropriate. [NFPA 54: 13.2.25]
511.2.23 Where a table permits more than one (1) diam-
eter of pipe to be used for a connector or vent, all the per-
mitted sizes shall be permitted to be used. [NFPA
54:13.2.26]

G.1.1 Example 1: Single Draft-Hood-Equipped Appli-
ance. An installer has a 120,000-Btu/h input appliance with
a five (5) inch diameter draft hood outlet that needs to be
vented into a ten (10) foot high Type B vent system. What
size vent should be used assuming (1) a five (5) foot lateral
single-wall metal vent connector is used with two (2) 90 de-
gree elbows or (2) a five (5) foot lateral single-wall metal vent
connector is used with three (3) 90 degree elbows in the vent
system? (See Figure G.1.1).
Solution
Table 5-9 should be used to solve this problem because sin-
gle-wall metal vent connectors are being used with a Type B
vent, as follows:
(1) Read down the first column in Table 5-9 until the row
associated with a ten (10) foot height and five (5) foot
lateral is found. Read across this row until a vent capac-
ity exceeding 120,000 Btu/h is located in the shaded
columns labeled NAT Max for draft-hood-equipped ap-
pliances. In this case, a five (5) inch diameter vent has a
capacity of 122,000 Btu/h and can be used for this ap-
plication.
If three (3) 90 degree elbows are used in the vent system,
the maximum vent capacity listed in the tables must be
reduced by 10 percent (See NFPA 54:13.1.3). This im-
plies that the five (5) inch diameter vent has an adjusted
capacity of only 1 10,000 Btu/h. In this case, the vent sys-
tem must be increased to six (6) inches in diameter. See
the following calculations:

FIGURE G.1(m) MULTISTORY GAS VENT DESIGN PROCEDURE

From Table 5-10, select six (6) inch vent.
186,000x0.90=167,000
This figure is exceeding the required 120,000.
Therefore, use a six (6) inch vent and connector where
three (3) elbows are used.
G.1.2. Example 2: Single Fan-Assisted Appliance. An in-
staller has an 80,000 Btu/h input fan-assisted appliance that
must be installed using ten (10) feet of lateral connector at-
tached to a thirty (30) foot high Type B vent. Two (2) 90 de-
gree elbows are needed for the installation. Can a single-wall
metal vent connector be used for this application? See Figure
G.1.2.
Solution
Table 5-9 refers to the use of single-wall metal vent connec-
tors with Type B vent. In the first column find the row associ-
ated with a thirty (30) foot height and a ten (10) foot lateral.
Read across this row, looking at the FAN Min and FAN Max
columns, to fmd that a three (3) inch diameter single-wall metal
vent connector is not recommended. Moving to the next larger

size single-wall connector (four (4) inch), we find that a four (4)
inch diameter single- wall metal connector has a recommended
maximum vent capacity of 144,000 Btu/h. The 80,000 Btu/h
fan-assisted appliance is outside this range, so the conclusion
is that a single- wall metal connector could be used to vent the
appliance. Table 5-9 shows the acceptable range of vent ca-
pacities for a four (4) inch vent with five (5) feet of lateral to
be between 72,000 Btu/h and 157,000 Btu/h.
If the appliance cannot be moved closer to the vertical
vent, then a Type B vent could be used as the connector ma-
terial. In this case, Table 5-8 shows that, for a thirty (30) foot
high vent with ten (10) feet of lateral, the acceptable range of
vent capacities for a four (4) inch diameter vent attached to a
fan-assisted appliance is between 37,000 Btu/h and 150,000
Btu/h.
G.1.3. Example 3: Interpolating Between Table Values. An
installer has an 80,000 Btu/h input appliance with a four (4)
inch diameter draft hood outlet that needs to be vented into a
twelve (12) foot high Type B vent. The vent connector has a
5 -foot lateral length and is also Type B vent. Can this appli-
ance be vented using a four (4) inch diameter vent?
Solution
Table 5-8 is used in the case of an all Type B Vent system.
However, since there is no entry in Table 5-8 for a height of
twelve (12) feet, interpolation must be used. Read down the
four (4) inch diameter NAT Max column to the row associated
with a ten (10) foot height and five (5) foot lateral to find the
capacity value of 77,000 Btu/h. Read further down to the fif-
teen (15) foot height, five (5) foot lateral row to fmd the ca-
pacity value of 87,000 Btu/h. The difference between the
fifteen (15) foot height capacity value and the ten (10) foot
height capacity value is 10,000 Btu/h. The capacity for a vent
system with a twelve (12) foot height is equal to the capacity
for a ten (10) foot height plus two-fifths (%) of the difference
between the ten (10) foot and fifteen (15) foot height values,
or 77,000 4- 2/5 X 10,000 = 81,000 Btu/h. Therefore, a four (4)
inch diameter vent can be used in the installation.
G.2 Examples Using Common Venting Tables.
G.2.1 Example 4: Common Venting Two Draft-Hood-
Equipped Appliances. A 35,000-Btu/h water heater is to be
common vented with a 150,000 Btu/h furnace, using a com-
mon vent with a total height of thirty (30) feet. The connec-
tor rise is two (2) feet for the water heater with a horizontal
length of four (4) feet. The connector rise for the furnace is
three (3) feet with a horizontal length of eight (8) feet. Assume
single-wall metal connectors will be used with Type B vent.
What size connectors and combined vent should be used in
this installation?

connectors attached to Type B vertical vents. In the vent con-
nector capacity portion of Table 5-15, find the row associated
with a thirty (30) foot vent height. For a two (2) foot rise on
the vent connector for the water heater, read the shaded
columns for draft-hood-equipped appliances to find that a
three (3) inch diameter vent connector has a capacity of
37,000 Btu/h. Therefore, a three (3) inch single- wall metal
vent connector can be used with the water heater. For a draft-
hood-equipped furnace with a three (3) foot rise, read across
the appropriate row to find that a five (5) inch diameter vent
connector has a maximum capacity of 120,000 Btu/h (which
is too small for the furnace), and a six (6) inch diameter vent
connector has a maximum vent capacity of 172,000 Btu/h.
Therefore, a six (6) inch diameter vent connector should be
used with the 150,000 Btu/h furnace. Since both vent con-
nector horizontal lengths are less than the maximum lengths
listed in Table 5-8, the table values can be used without ad-
justments.
In the common vent capacity portion of Table 5-15, find
the row associated with a thirty (30) foot vent height and read
over to the NAT + NAT portion of the six (6) inch diameter
column to find a maximum combined capacity of 257,000
Btu/h. Since the two (2) appliances total only 185,000 Btu/h,
a six (6) inch common vent can be used.
G.2.2 Example 5(a): Common Venting a Draft-Hood-
Equipped Water Heater witii a Fan- Assisted Furnace into
a Type B Vent. In this case, a 35,000-Btu/h input draft-hood-
equipped water heater with a four (4) inch diameter draft hood
outlet, two (2) feet of connector rise, and four (4) feet of hor-
izontal length is to be common vented with a 100,000 Btu/h
fan-assisted ftimace with a four (4) inch diameter flue collar,
three (3) feet of connector rise, and six (6) feet of horizontal
length. The common vent consists of a thirty (30) foot height
of Type B vent. What are the recommended vent diameters for
each connector and the common vent? The installer would like
to use a single-wall metal vent connector. See Figure G.2.2.
Solution (See Table 5-15)
Water Heater Vent Connector Diameter Since the water
heater vent connector horizontal length of four (4) feet is less
than the maximum value listed in Table 5-15, the venting
table values can be used without adjustment. Using the Vent
Connector Capacity portion of Table 5-15, read down the
Total Vent Height (H) column to thirty (30) feet and read
across the two (2) feet Connector Rise (R) row to the first
Btu/h rating in the NAT Max column that is equal to or ex-
ceeding the water heater input rating. The table shows that a
three (3) inch vent connector has a maximum input rating of
37,000 Btu/h. Although this rating is exceeding the water
heater input rating, a three (3) inch vent connector is prohib-
ited by Section 5 1 1 . 1 . 1 (5). A four (4) inch vent connector has
a maximum input rating of 67,000 Btu/h and is equal to the
draft hood outlet diameter. A four (4) inch vent connector is

WATER HEATERS
selected. Since the water heater is equipped with a draft hood,
there are no minimum input rating restrictions.
Furnace Vent Connector Diameter Using the Vent Con-
nector Capacity portion of Table 5-15, read down the Total
Vent Height (H) column to thirty (30) feet and across the three
(3) foot Connector Rise (R) row. Since the furnace has a fan-
assisted combustion system, fmd the first FAN Max column
with a Btu/h rating exceeding the furnace input rating. The
four (4) inch vent connector has a maximum input rating of
1 19,000 Btu/h and a minimum input rating of 85,000 Btu/h.
The 100,000-Btu/h furnace in this example falls within
this range, so a four (4) inch connector is adequate. Since the
furnace vent connector horizontal length of six (6) feet is less
than the maximum value listed in Table 5-8, the venting table
values can be used without adjustment. If the ftimace had an
input rating of 80,000 Btu/h, then a Type B vent connector
would be needed in order to meet the minimum capacity limit
(See Table 5-14).
Common Vent Diameter The total input to the common
vent is 135,000 Btu/h. Using the Common Vent Capacity por-
tion of Table 5-15, read down the Vent Height (H) column to
thirty (30) feet and across this row to fmd the smallest vent di-
ameter in the FAN + NAT column that has a Btu/h rating
equal to or exceeding 135,000 Btu/h. The four (4) inch com-
mon vent has a capacity of 132,000 Btu/h and the five (5)
inch common vent has a capacity of 202,000 Btu/h. There-
fore, the five (5) inch common vent should be used in this ex-
ample.
Summary: In this example, the installer can use a four (4) inch
diameter, single-wall metal vent connector for the water
heater and a four (4) inch diameter, single-wall metal vent
connector for the furnace. The common vent should be a five
(5) inch diameter Type B vent.
G.2.3 Example 5(b): Common Venting into an Interior Ma-
sonry Chimney. In this case, the water heater and fan-assisted
furnace of Example 5(a) are to be common-vented into a clay-
tile-lined masonry chimney with a thirty (30) foot height. The
chimney is not exposed to the outdoors below the roof line.
The internal dimensions of the clay tile liner are nominally
eight (8) inches x twelve (12) inches. Assuming the same vent
connector heights, laterals, and materials found in example
5(a), what are the recommended vent connector diameters,
and is this an acceptable installation?
Solution
Table 5-17 is used to size common venting installations in-
volving single- wall connectors into masonry chimneys.
Water Heater Vent Connector Diameter Using Table 5-
17, Vent Connector Capacity, read down the Vent Height (H)
column to thirty (30) feet, and read across the two (2) foot
Connector Rise (R) row to the first Btu/h rating in the NAT
Max column that is equal to or exceeding the water heater
input rating. The table shows that a three (3) inch vent con-
nector has a maximum input of only 31,000 Btu/h, while a
four (4) inch vent connector has a maximum input of 57,000
Btu/h. A four (4) inch vent connector must therefore be used.
Furnace Vent Connector Diameter Using the Vent Con-
nector Capacity portion of Table 5-17, read down the total
Vent Height (H) column to thirty (30) feet and across the three
(3) feet Connector Rise (R) row. Because the furnace has a
fan-assisted combustion system, find the first FAN Max col-
umn with a Btu/h rating exceeding the furnace input rating.
The four (4) inch vent connector has a maximum input rating
of 127,000 Btu/h and a minimum input rating of 95,000
Btu/h. The 100,000 Btu/h furnace in this example falls within
this range, so a four (4) inch connector is adequate.
Masonry Chimney. From Table G.2.3, the equivalent area
for a nominal liner size of eight (8) inches x twelve (12)
inches is sixty-three and six-tenths (63.6) of a square inch.
Using Table 5-17, Common Vent Capacity, read down the
FAN + NAT column under the Minimum Internal Area of
Chimney value of sixty-three (63) to the row for thirty (30)
foot height to find a capacity value of 739,000 Btu/h. The
combined input rating of the furnace and water heater,
135,000 Btu/h, is less than the table value so this is an ac-
ceptable installation.
Section 511.1.8 requires the common vent area to not exceed
seven (7) times the smallest listed appliance categorized vent
area, flue collar area, or draft hood outlet area. Both appli-
ances in this installation have four (4) inch diameter outlets.
From Table G.2.3, the equivalent area for an inside diameter
of four (4) inches is twelve and two-tenths (12.2) of a square
inch. Seven (7) times twelve and two-tenths (12,2) equals
eighty-five and four-tenths (85.4), which is exceeding sixty-
three and six-tenths (63.6), so this configuration is accept-
able.
G.2.4 Example 5(c): Common Venting into an Exterior
Masonry Chimney. In this case, the water heater and fan-as-
sisted furnace of Examples 5(a) and 5(b) are to be common-
vented into an exterior masonry chimney. The chimney
height, clay-tile-liner dimensions, and vent connector heights
and laterals are the same as in Example 5(b). This system is
being installed in Charlotte, North Carolina. Does this exte-
rior masonry chimney need to be relined? If so, what corru-
gated metallic liner size is recommended? What vent
connector diameters are recommended? See Table G.2.3 and
Figure 5-14.
Solution
According to 511.2.17, Type B vent connectors are re-
quired to be used with exterior masonry chimneys. Use Table
5-21 and Table 5-22 to size FAN+NAT common venting in-
stallations involving Type-B double- wall connectors into ex-
terior masonry chimneys.
The local 99 percent winter design temperature needed to
use Table 5-21 and Table 5-22 can be found in the ASHRAE
Handbook - Fundamentals. For Charlotte, North Carolina,
this design temperature is 19^F (-7.22°C).
Chimney Liner Requirement. As in Example 5(b), use the
sixty-three (63) square inch column of Table 5-21 to the thirty

WATER HEATERS
(30) foot height row to find that the combined appliance max-
imum input is 747,000 Btu/h. The combined input rating of
the appliance in this installation, 135,000 Btu/h, is less than
the maximum value, so this criterion is satisfied. Table 5-22,
at a 19°F (-7.22°C) design temperature, and at the same vent
height and internal area used earlier, shows that the minimum
allowable input rating of a space-heating appliance is 470,000
Btu/h. The furnace input rating of 100,000 Btu/h is less than
this minimum value. So this criterion is not satisfied, and an
alternative venting design needs to be used, such as a Type B
vent shown in Example 5(a) or a listed chimney liner system
shown in the rest of the example.
According to Section 511.2.19, Table 5-9 or Tables 5-14
or 5-15 are used for sizing corrugated metallic liners in ma-
sonry chimneys, with the maximum common vent capacities
reduced by 20 percent. This example will be continued as-
suming Type B vent connectors.
Water Heater Vent Connector Diameter Using Table 5-
14 Connector Capacity, read down the total Vent Height (H)
column to thirty (30) feet, and read across the two (2) foot
Connector Rise (R) row to the first Btu/hour rating in the NAT
Max column that is equal to or exceeding the water heater
input rating. The table shows that a three (3) inch vent con-
nector has a maximum capacity of 39,000 Btu/h. Although
this rating is exceeding the water heater input rating, a three
(3) inch vent connector is prohibited by Section 511.1.6. A
four (4) inch vent connector has a maximum input rating of
70,000 Btu/h and is equal to the draft hood outlet diameter. A
four (4) inch vent connector is selected.
Furnace Vent Connector Diameter Using Table 5-14,
Vent Connector Capacity, read down the total Vent Height (H)
column to thirty (30) feet, and read across the three (3) foot
Connector Rise (R) row to the first Btu/h rating in the FAN
MAX column that is equal to or exceeding the fiimace input
rating. The 100,000 Btu/h furnace in this example falls within
this range, so a four (4) inch connector is adequate.
Chimney Liner Diameter The total input to the common
vent is 1 35,000 Btu/h. Using the Common Vent Capacity por-
tion of Table 5-14, read down the total Vent Height (H) col-
umn to thirty (30) feet and across this row to find the smallest
vent diameter in the FAN + NAT column that has a Btu/h rat-
ing exceeding 135,000 Btu/h. The four (4) inch common vent
has a capacity of 138,000 Btu/h. Reducing the maximum ca-
pacity by 20 percent (See 13.2.19) results in a maximum ca-
pacity for a four (4) inch corrugated liner of 110,000 Btu/h,
less than the total input of 135,000 Btu/h. So a larger liner is
needed. The five (5) inch common vent capacity listed in
Table 5-14 is 210,000 Btu/h, and after reducing by 20 percent
is 168,000 Btu/h. Therefore, a five (5) inch corrugated metal
liner should be used in this example.
Single Wall Connectors. Once it has been established that
relining the chimney is necessary. Type B double-wall vent
connectors are not specifically required. This example could
be redone using Table 5-15 for single-wall vent connectors.
For this case, the vent connector and liner diameters would be
the same as found for Type B double- wall connectors.
The following is originally from NFPA 54, National Fuel Gas
Code, which contains additional reference.
Example of Combination of Indoor and Outdoor Com-
bustion and Ventilation Opening Design.
J.l Example of Combination Indoor and Outdoor Com-
bustion Air Opening. Determine the required combination
of indoor and outdoor combustion air opening sizes for the
following appliance installation example.
Example Installation: A fan-assisted furnace and a draft-
hood-equipped water heater with the following inputs are lo-
cated in a fifteen (15) foot x thirty (30) foot basement with an
eight (8) foot ceiling. No additional indoor spaces can be used
to help meet the appliance combustion air needs.
Fan- Assisted Furnace Input: 100,000 Btu/h
Draft-Hood-Equipped Water Heater Input: 40,000 Btu/h
Solution
(1) Determine the total available room volume: Equipment
room volume:
Fifteen (15) feet x thirty (30) feet with an eight (8) foot
ceiling = thirty-six-hundred (3,600) cubic feet
(2) Determine the total required volume: The standard method
to determine combustion air will be used to calculate the
required volume.
The combined input for the appliances located in the
basement is calculated as follows:
100,000 Btu/h +40,000 Btu/h = 140,000 Btu/h
The Standard Method requires that the required volume
be determined based on fifty (50) cubic feet per 1,000
Btu/hour.
Using Table A.9. 3.2.1, the required volume for a 140,000
Btu/h water heater is seven-thousand (7,000) cubic feet.
Conclusion: Indoor volume is insufficient to supply com-
bustion air since the total of thirty-six-hundred (3,600)
cubic feet does not meet the required volume of seven-
thousand (7,000) cubic feet. Therefore, additional com-
bustion air must be provided from the outdoors.
(3) Determine ratio of the available volume to the required
volume:
3,600 ft.^
7,000 ft.^
■ = 0.51
(4) Determine the reduction factor to be used to reduce the
fall outdoor air opening size to the minimum required based
on ratio of indoor spaces:
1.00 - 0.51 (fi-om Step 3) = 0.49

WATER SUPPLY AND DISTRIBUTION
I 601.0 Hot and Cold Water Required.
601.1 Except where not deemed necessary for safety or sani-
tation by the Authority Having Jurisdiction, each plumbing
fixture shall be provided with an adequate supply of potable
running water piped thereto in an approved manner, so
arranged as to flush and keep it in a clean and sanitary condi-
tion without danger of backflow or cross-connection. Water
closets and urinals shall be flushed by means of an approved
flush tank or flushometer valve.
Exceptions:
II (1) [HCD h HCD 2, andDWR] Listed fixtures that do not
require water for their operation and are not connected to
the water supply.
(2) [HCD 1 & HCD 2] For limited-density owner-built rural
dwellings, potable water shall be available to the
dwelling site, although such water need not be pressur-
ized. Where water is not piped from a well, spring, cis-
tern, or other source, there shall be a minimum reserve
of 50 gallons (189 L) of potable water available. Where
water delivery is pressurized, piping shall be installed in
accordance with the provisions of this chapter
(3) [HCD 1 & HCD 2] Where deemed not necessary for
safety or sanitation by the Enforcing Agency.
(4) [HCD 1 & HCD 2] Recycled water or treated graywater
may be allowed as specified in Chapter 16 Part II of this
code.
(5) [D WR] Where a public agency requires a building to use
recycled water to flush water closets and urinals in ac-
cordance with California Water Code 13554.
In occupancies where plumbing fixtures are installed for
private use, hot water shall be required for bathing, washing,
laundry, cooking purposes, dishwashing or maintenance. In
occupancies where plumbing fixtures are installed for public
use, hot water shall be required for bathing and washing pur-
poses. This requirement shall not supersede the requirements
for individual temperature control limitations for public lava-
tories, bathtubs, whirlpool bathtubs and shower control valves.
601.2 Identification of a Potable and Non-potable Water
System. In buildings where potable water and non-potable

146
2010 CALIFORNIA PLUMBING CODE
WATER SUPPLY AND DISTRIBUTION
609.9.1 The pipe system shall be flushed with clean,
potable water until only potable water appears at the points
of outlet.
609.9.2 The system or parts thereof shall be filled with a
water-chlorine solution containing not less than fifty (50)
parts per million of chlorine, and the system or part thereof
shall be valved-off and allowed to stand for twenty- four
(24) hours; or, the system or part thereof shall be filled
with a water-chlorine solution containing not less than
two-hundred (200) parts per million of chlorine and al-
lowed to stand for three (3) hours.
609.9.3 Following the allowed standing time, the system
shall be flushed with clean, potable water until the chlo-
rine residual in the water coming from the system does
not exceed the chlorine residual in the flushing water.
609.9.4 The procedure shall be repeated if it is shown by
bacteriological examination made by an approved agency
that contamination persists in the system.
609.10 Water Hammer. [Not adopted by HCD] Building
water supply systems where quick-acting valves are installed
I shall be provided with water hammer arrester(s) to absorb
high pressures resulting from the quick closing of these
I valves. Water hammer arrestors shall be approved mechani-
cal devices in accordance with the applicable standard(s) ref-
erenced in Table 14-1 and shall be installed as close as
possible to quick-acting valves.
609.10.1 Mechanical Devices. When listed mechanical
devices are used, the manufacturer's specifications as to
location and method of installation shall be followed,
609.11 [OSHPD 1,2 Si 4] Refer to Title 24, Part 2 of the
California Building Code for seismic anchorage and bracing
requirements and accommodations for building displace-
ments.
610.0 Size of Potable Water Piping.
610.1 The size of each water meter and each potable water
supply pipe from the meter or other source of supply to the
fixture supply branches, risers, fixtures, connections, outlets,
or other uses shall be based on the total demand and shall be
determined according to the methods and procedures outlined
in this section. Water piping systems shall be designed to en-
sure that the maximum velocities allowed by the code and the
applicable standard are not exceeded.
610.2 Whenever a water filter, water softener, backflow pre-
vention device or similar device is installed in any water sup-
ply line, the pressure loss through such devices shall be
included in the pressure loss calculations of the system, and
the water supply pipe and meter shall be adequately sized to
provide for any such pressure loss.
No water filter, water softener, backflow prevention de-
vice, or similar device regulated by this code shall be installed
in any potable water supply piping when the installation of such
device produces an excessive pressure drop in any such water
supply piping, hi the absence of specific pressure drop infor-
mation, the diameter of the inlet or outlet of any such device or
its connecting piping shall be not less than the diameter of such
water distribution piping to the fixtures served by the device.
Such devices shall be of a type approved by the Author-
ity Having Jurisdiction and shall be tested for flow rating and
pressure loss by an approved laboratory or recognized testing
agency to standards consistent with the intent of this chapter.
610.3 The quantity of water required to be suppHed to every
plumbing fixture shall be represented by fixture units, as
shown in Table 6-5. Equivalent fixture values shown in Table
6-5 include both hot and cold water demand.
610.4 Systems within the range of Table 6-6 shall be permit-
ted to be sized from that table or by the method set forth in
Section 610.5.
Listed parallel water distribution systems shall be in-
stalled in accordance with their listing, but at no time shall
any portion of the system exceed the maximum velocities al-
lowed by the code.
610.5 Except as provided in Section 610.4, the size of each
water piping system shall be determined in accordance with
the procedure set forth in Appendix A. For alternate methods
of sizing water supply systems, see Appendix L.
610.6 Except where the type of pipe used and the water char-
acteristics are such that no decrease in capacity due to length
of service (age of system) is expected, friction-loss data shall
be obtained from the "Fairly Rough" or "Rough" charts in
Appendix A of this code. Friction or pressure losses in water
meter, valve, and fittings shall be obtained from the same
sources. Pressure losses through water-treating equipment,
backflow prevention devices, or other flow-restricting devices
shall be computed as required by Section 610.2.
610.7 On any proposed water piping installation sized using
Table 6-6, the following conditions shall be determined:
( 1 ) Total number of fixture units as determined from Table 6-
5, Equivalent Fixture Units, for the fixtures to be in-
stalled.
(2) Developed length of supply pipe from meter to most re-
mote outlet.
(3) Difference in elevation between the meter or other source
of supply and the highest fixture or outlet.
(4) Pressure in the street main or other source of supply at
the locality where the installation is to be made.
(5) In localities where there is a fluctuation of pressure in
the main throughout the day, the water piping system
shall be designed on the basis of the minimum pressure
available.
610.8 Size of Meter and Building Supply Pipe Using Table
6-6. The size of the meter and the building supply pipe shall
be determined as follows:
(1) Determine the available pressure at the water meter or
other source of supply.
(2) Subtract one-half Q/i) pound per square inch pressure
(3.4 kPa) for each foot (305 mm) of difference in eleva-
tion between such source of supply and the highest water
supply outlet in the building or on the premises.
2010 CALIFORNIA PLUMBING CODE

WATER SUPPLY AND DISTRIBUTION
(3) Use the "pressure range" group within which this pres-
sure will fall using Table 6-6.
(4) Select the "length" column that is equal to or longer than
the required length.
(5) Follow down the column to a fixture unit value equal to
or exceeding the total number of fixture units required
by the installation.
(6) Having located the proper fixture unit value for the re-
quired length, sizes of meter and building supply pipe as
found in the two (2) left-hand columns shall be applied.
No building supply pipe shall be less than three-quarters
(Va) of an inch (20 mm) in diameter.
610.9 Size of Branches. When Table 6-6 is used, the mini-
mum size of each branch shall be determined by the number
of fixture units to be served by that branch, the total devel-
oped length of the system, and the meter and street service
size as per Section 610.8. No branch piping is required to be
larger in size than that required by Table 6-6 for the building
supply pipe.
610.10 Sizing for Flushometer Valves. When using Table 6-
6 to size water supply systems serving flushometer valves,
the number of flushometer fixture units assigned to every sec-
tion of pipe, whether branch or main, shall be determined by
the number and category of flushometer valves served by that
section of pipe, in accordance with Table 6-7. Piping supply-
ing a flushometer valve shall be not less in size than the valve
inlet.
When using Table 6-7 to size water piping, care must be
exercised to assign flushometer fixture units based on the
number and category of fixtures served.

Notes:
' Size of the cold branch pipe, or both the hot and cold branch pipes.
^ Appliances, Appurtenances or Fixtures not included in this Table may be sized by reference to fixtures having a similar flow rate and frequency of use.
^ The listed fixture unit values represent their load on their cold water service. The separate cold water and hot water fixture unit value for fixtures having
both hot and cold water connections may each be taken as three-quarter QA) of the listed total value of the fixture.
"* The listed minimum supply branch pipe sizes for individual fixtures are the nominal (LD.) pipe size.
^ For fixtures or supply connections likely to impose continuous flow demands, determine the required flow in gallons per minute (GPM), and add it sepa-
rately to the demand (in GPM) for the distribution system or portions thereof
^ Assembly [Public Use (See Table 4- 1 )] .
^ When sizing flushometer systems, see Section 610.10.
^ Reduced fixture unit loading for additional hose bibbs is to be used only when sizing total building demand and for pipe sizing when more than one (1)

ondary interceptor. The second interceptor shall be properly
trapped and vented.
902.2 Traps serving sinks that are part of the equipment of bars,
soda fountains, and counters need not be vented when the lo-
cation and construction of such bars, soda fountains, and coun-
ters is such as to make it impossible to do so. When such
conditions exist, said sinks shall discharge by means of ap-
proved indirect waste pipes into a floor sink or other approved
type of receptor.

STORM DRAINAGE
1109.2 Methods of Testing Storm Drainage Systems. Ex-
cept for outside leaders and perforated or open-jointed drain
tile, the piping of storm drain systems shall be tested upon
completion of the rough piping installation by water or air,
I except that plastic pipe shall not be tested with air, and proved
tight. The Authority Having Jurisdiction shall be permitted to
require the removal of any cleanout plugs to ascertain whether
the pressure has reached parts of the system. One (1) of the
following test methods shall be used:
1109.2,1 Water Test. After piping has been installed, the
water test shall be applied to the drainage system, either
to the entire system or to sections. If the test is applied to
the entire system, all openings in the piping shall be
tightly closed except for the highest opening, and the sys-
tem shall be filled with water to the point of overflow. If
the system is tested in sections, each opening shall be
tightly plugged except for the highest opening of the sec-
tion under test, and each section shall be filled with
water, but no section shall be tested with less than a ten
(10) foot (3,048 mm) head of water. In testing succes-
sive sections, not less than the upper ten (10) feet (3,048
mm) of the next preceding section shall be tested so that
no joint of pipe in the building (except the uppermost ten
(10) feet (3,048 mm) of a roof drainage system, which
shall be filled with water to the flood level of the upper-
most roof drain) shall have been submitted to a test of
less than a ten (10) foot (3,048 mm) head of water. The
water shall be kept in the system or in the portion under
test for not less than fifteen (15) minutes before inspec-
tion starts; the system shall then be tight at all points.
1109.2.2 Air Test The air test shall be made by attach-
ing an air compressor testing apparatus to any suitable
opening after closing other inlets and outlets to the sys-
tem, forcing air into the system until there is a uniform
gauge pressure of five (5) psi (34.5 kPa) or sufficient
pressure to balance a column of mercury ten (10) inches
(254 mm) in height. This pressure shall be held without
introduction of additional air for a period of not less than
fifteen (15) minutes. |
1109.2.3 Exceptions. When circumstances exist that
make air and water tests described in Sections 1109.2.1
and 1109.2.2 above impractical, see Section 103.5.3.3.

Notes:
^ Maximum discharge capacity, gpm (L/s) with approximately 1% inch (44 mm) head of water at the drain.
^ For rainfall rates other than those listed, determine the allowable roof area by dividing the area given in the 1 -inch/hour (25 mm/hour) column by the de-
sired rainfall rate.
^ Vertical piping may be round, square, or rectangular. Square pipe shall be sized to enclose its equivalent roundpipe. Rectangular pipe shall have not less than
the same cross-sectional area as its equivalent round pipe, except that the ratio of its side dimensions shall not exceed 3 to 1.

be provided (in cubic feet per hour) shall be determined di-
rectly from the manufacturer's input ratings of the gas uti-
lization appliance served. Where the input rating is not
indicated, the gas supplier, appliance manufacturer, or a
qualified agency shall be contacted or the rating from Table
12-1 shall be used for estimating the volume of gas to be
supplied. The total connected hourly load shall be used as
the basis for piping sizing, assuming the appliance is oper-
ating at frill capacity simultaneously. [NFPA 54:5.4.2]
Exception: Sizing shall be permitted to be based upon
established load diversity factors. [NFPA 54:5.4.2.2] |

1215.0 Interconnections Between Gas Piping Systems.
[NFPA 54:5.3]
1215.1 Interconnections Supplying Separate Users. Where
two (2) or more meters, or two (2) or more service regulators
where meters are not provided, are located on the same prem-
ises and supply separate users, the gas-piping systems shall
not be interconnected on the outlet side of the meters or serv-
ice regulators. [NFPA 54:5.3.1]
1215.2 Interconnections for Standby Fuels. Where supple-
mentary gas for standby use is connected downstream from a
meter or a service regulator where a meter is not provided, a de-
vice to prevent backflow shall be installed. [NFPA 54:5.3.2.1]
A three-way valve installed to admit the standby supply and at
the same time shut off the regular supply shall be permitted to
be used for this purpose. [NFPA 54:5.3.2.2]
1216.0 Required Gas Supply.
1216.1 The following regulations, as set forth in this section
and in Section 1217.0, Required Gas Piping Size, shall be the
standard for the installation of gas piping. Natural gas regu-
lations and tables are based on the use of gas having a specific
gravity of sixty-hundredths (0.60), supplied at six (6) to eight
(8) inches (152-203 mm) water column pressure at the out-
let of the meter or regulator. For undiluted liquefied petro-
leum gas, gas piping shall be permitted to be sized at eleven
(11) inches (279 mm) water column pressure at the outlet of
the meter or regulator and specific gravity of one and fifty-
hundredths(1.50).
Note: Where gas of a different specific gravity is to be deliv-
ered, the serving gas supplier should be contacted for specific
gravity conversion factors to use in sizing piping systems from
the pipe sizing tables in this chapter.
1216.2 The hourly volume of gas required at each piping out-
let shall be taken as not less than the maximum hourly rating
as specified by the manufacturer of the appliance or appli-
ances to be connected to each such outlet.
1216.3 Where the gas appliances to be installed have not been
definitely specified, Table 12-1 shall be permitted to be used
as a reference to estimate requirements of typical appliances.
To obtain the cubic feet per hour (L/sec.) of gas required,
divide input of appliances by the average Btu (Watt-hour)
heating value per cubic foot (L) of the gas. The average Btu
(Watt-hour) per cubic foot (L) of the gas in the area of the in-
stallation shall be permitted to be obtained from the serving
gas supplier.
1216.4 The size of the supply piping outlet for any gas appH-
ance shall not be less than one-half (1/2) inch (15 mm).
The minimum size of any piping outlet for a mobile home
shall be three-quarters (%) of an inch (20 mm).
1217.0 Required Gas Piping Size.
1217.1 Pipe Sizing Methods. Where the pipe size is to be |
determined using any of the methods in Sections 1217.1.1
through 1217.1.3, the diameter of each pipe segment shall be
obtained from the pipe-sizing tables in Section 1217.2 or from
the sizing equations in Section 1217.3. [NFPA 54:6.1]
1217.1.1 Longest Length Method. The pipe size of each |
section of gas piping shall be determined using the longest
length of piping from the point of delivery to the most re-
216

mote outlet and the load of the section (See calculation ex-
ample in Figure 12-2). [NFPA 54:6.1.1]
1217.1.2 Branch Length Method. Pipe shall be sized
as follows: [NFPA 54:6.1.2]
(A) Pipe size of each section of the longest pipe run from
the point of delivery to the most remote outlet shall
be determined using the longest run of piping and
the load of the section.
(B) The pipe size of each section of branch piping not
previously sized shall be determined using the
length of piping from the point of delivery to the
most remote outlet in each branch and the load of
the section.
I 1217.1.3 Hybrid Pressure. The pipe size for each sec-
tion of higher-pressure gas piping shall be determined
using the longest length of piping from the point of de-
livery to the most remote line pressure regulator. The
pipe size from the hne pressure regulator to each outlet
shall be determined using the length of piping from the
regulator to the most remote outlet served by the regula-
tor. [NFPA 54:6.1.3]
I 1217.2 Tables for Sizing Gas-Piping Systems. Tables 12-8
through 12-41 shall be used to size gas piping in conjunction
with one (1) of the methods described in Sections 1217.1.1
through 1217.1.3. [NFPA 54:6.2]
I 1217.3 Sizing Equations. The inside diameter of smooth- wall
pipe or tubing shall be determined by the sizing equations 12-
1 or 12-2, using the equivalent pipe length determmed by Sec-
tions 1217.1.1 through 1217.1.3. [NFPA 54:6.4]

1217.4 To determine the size of each section of pipe in any
system within the range of the Table, proceed as follows: |
(A) Measure the length of the pipe from the gas meter loca-
tion to the most remote outlet on the system.
(B) Select the length in feet column and row showing the dis- 1
tance, or the next longer distance if the table does not
give the exact length.
(C) Starting at the most remote outlet, find in the row just se-
lected the gas demand for that outlet. If the exact figure
of demand is not shown, choose the next larger figure in
the row.
(D) At the top of this column will be found the correct size
of pipe.
(E) Using this same row, proceed in a similar manner for
each section of pipe serving this outlet. For each section
of pipe, determine the total gas demand supplied by that
section. Where gas piping sections serve both heating
and cooling appliances and the installation prevents both |
units from operating simultaneously, only the larger of
the two (2) demand loads needs be used in sizing these
sections.
(F) Size each section of branch piping not previously sized
by measuring the distance from the gas meter location to
the most remote outlet in that branch and follow the pro-
cedures of steps B, C, D, and E above. |
2010 CALIFORNIA PLUMBING CODE

FUEL PIPING
Note: Size branch piping in the order of their distance from
the meter location, beginning with the most distant outlet not
previously sized.
1217.5 For conditions other than those covered by Section
1217.1, such as longer runs or greater gas demands, the size
of each gas piping system shall be determined by standard
engineering methods acceptable to the Authority Having Ju-
risdiction, and each such system shall be so designed that the
total pressure drop between the meter or other point of sup-
ply and any outlet when full demand is being supplied to all
I outlets, shall comply with the requirements of Section 1209.4.
1217.6 Where the gas pressure exceeds fourteen (14) inches
(356 mm) or less than six (6) inches (152 mm) of water col-
umn, or when diversity demand factors are used, the design,
pipe, sizing, materials, location, and use of such systems first
shall be approved by the Authority Having Jurisdiction. Pip-
ing systems designed for pressures exceeding the serving gas
supplier's standard delivery pressure shall have prior verifi-
cation from the gas supplier of the availability of the design
pressure.

*EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydrauHc efficiency between different tubing sizes. The greater the value of EHD, the
greater the gas capacity of the tubing.
Notes:
(1) Table includes losses for four 90 degree bends and two end fittings. Tubing runs with larger numbers of bends and/or fittings shall be increased by an equiva-
lent length of tubing to the following equation: L=l3n, where L is additional length (ft) of tubing and n is the number of additional fittings and/or bends.
(2) All t<ible entries are rounded to 3 significant digits.

greater the gas capacity of the tubing.
Notes:
(1) Table does not include effect of pressure drop across the Hne regulator. Where regulator loss exceeds Vi psi (based on 13 in. w.c. outlet pressure), DO NOT
USE THIS TABLE. Consult with regulator manufacturer for pressure drops and capacity factors. Pressure drops across a regulator may vary with flow rate.
(2) CAUTION: Capacities shown in table may exceed maximum capacity for a selected regulator. Consult with regulator or tubing manufacturer for guidance.
(3) Table includes losses for four 90 degree bends and two end fittings. Tubing runs with larger numbers of bends and/or fittings shall be increased by an equivalent
length of tubing to the following equation: L = \3n, where L is additional length (ft) of tubing and n is the number of additional fittings and/or bends.

1311.1.1 Components include but are not limited to con-
tainers, valves, valve seats, lubricants, fittings, gaskets,
and interconnecting equipment including hose. Easily ig-
nitable materials should be avoided.
Compatibility involves both combustibility and ease
of ignition. Materials that bum in air will bum violently
in pure oxygen at normal pressure and explosively in
pressurized oxygen. Also, many materials that do not
bum in air will do so in pure oxygen, particularly under
pressure. Metals for containers and piping have to be
carefully selected, depending on service conditions. The
various steels are acceptable for many appHcations, but
some service conditions can call for other materials (usu-
ally copper or its alloys) because of their greater resist-
ance to ignition and lower rate of combustion. Similarly,
materials that can be ignited in air have lower ignition
energies in oxygen. Many such materials can be ignited
by friction at a valve seat, stem packing or by adiabatic
compression produced when oxygen at high pressure is
rapidly introduced into a system initially at low pressure.
1311.1.2 Materials used in central supply systems shall
meet the following requirement [NFPA 99:5.1 .3.4.4]:
In those portions of systems intended to handle oxy-
gen or nitrous oxide at gauge pressures of less than three-
hundred (300) psi (2,070 kPa), material constmction
shall be compatible with oxygen under the temperatures
and pressures to which the components can be exposed
in the containment and use of oxygen, nitrous oxide,
mixtures of these gases, or mixtures containing more

1312.0 Plan Review.
1312.1 Before any medical gas or medical vacuum system is
installed or altered in any hospital, medical facility, or clinic,
duplicate plans and specifications shall be filed with the Au-
thority Having Jurisdiction. Approval ofthe plans shall be ob-
tained prior to issuance of any permit by the Authority Having
Jurisdiction.
1312.2 Plans and specifications shall show the following, in
detail:
1312.2.1 Plot plan ofthe site, drawn to scale, indicating
the location of existing or new cylinder storage areas,
property lines, driveways, and existing or proposed
buildings.
1312.2.2 Piping layout ofthe proposed piping system or
alteration, including alarms, valves, origin of gases, and
user outlets/inlets. The demand and loading of any pip-
ing, existing or future, shall also be indicated.
1312.2.3 Complete specification of materials.
1312.3 Plans and specifications submitted to the Authority
Having Jurisdiction shall clearly indicate the nature and ex-
tent of the work proposed and shall show in detail that such
work will conform to the provisions of this code.
1312.4 A record of as-built plans and valve identification
records shall remain on the site at all times.
1313.0 System Performance.
1313.1 Required Operating Pressures. Medical gas and
medical vacuum systems shall be capable of delivering serv-
ice in the pressure ranges hsted in Table 13-1.
1313.2 Minimum Flow Rates. Medical gas and medical vac-
uum systems shall be capable of supplying the flow rates
listed in Table 13-2.
1313.3 Minimum Station Outlets/Inlets. Station outlets and
inlets for medical gas and medical vacuum systems shall be
provided as listed in Table 13-3.
1314.0 Required Pipe Sizing.
1314.1 Where the maximum demand for each medical gas or
vacuum system and the maximum length of piping between
the source equipment and the most distant station outlet/inlet
do not exceed the values in Table 13-6, the size of pipe of
each section of the system shall be determined using Tables
13-4 and 13-6. The size for systems beyond the range of Table
13-6 shall be determined by using the methods set forth in
Section 1314.3 of this chapter.
1314.2 To determine the size of each section of pipe in any
system within the range of Table 13-6, proceed as follows:
1314.2.1 Measure the length ofthe pipe from the source
equipment location to the most remote station inlet/out-
let on the system.
1314.2.2 In Table 13-6, select the column showing that
distance, or the next longer distance if the table does not
give the exact length.
1314.2.3 Starting at the most remote outlet/inlet, find in
the vertical column just selected the medical gas or vac-
uum demand for that inlet/outlet. If the exact figure of
demand is not shown, choose the next larger figure below
in the column.
1314.2.4 Opposite this demand figure, in the first col-
umn at the left in Table 13-6, will be found the correct
size of pipe.
1314.2.5 Using this same vertical column, proceed in a
similar manner for each section of pipe serving this
inlet/outlet. For each section of pipe, determine the total
gas or vacuum demand supplied by the section, using
Table 13-4.

CHAPTER 15
FIRESTOP PROTECTION
1501.0 General Requirements.
1501.1 Applicability. Piping penetrations of required fire-re-
sistance-rated walls, partitions, floors, floor/ceiling assem-
blies, roof/ceiling assemblies, or shaft enclosures shall be
protected in accordance with the requirements of the Build-
ing Code, and this chapter.
1502.0 Plans and Speciflcations.
1502.1 Plans and specifications shall indicate with sufficient
detail how penetrations of fire-resistance-rated assemblies
shall be firestopped prior to obtaining design approval.
1503.0 Installation.
1503.1 Firestop materials shall be installed in accordance
with this chapter, the Building Code, and the manufacturer's
instructions.
1504.0 Definitions.
1504.1 Penetration Firestop System. A specific assemblage
of field-assembled materials, or a factory-made device, which
has been tested to a standard test method and, when installed
properly on penetrating piping materials, is capable of main-
taining the fire- resistance rating of assemblies penetrated.
1504.2 F Rating. The time period that the penetration firestop
system limits the spread of fire through the penetration, when
tested in accordance with ASTM E 814, Standard for Fire
I Tests of Through-Penetration Fire Stops, or UL 1479, Stan-
dard for Fire Tests of Through-Penetration Fires tops.
1504.3 T Rating. The time period that the penetration firestop
system, including the penetrating item, limits the maximum
temperature rise of 325T (163°C) above its initial temperature
through the penetration on the nonfire side, when tested in ac-
cordance with ASTM E 814, Standard for Fire Tests of
I Through-Penetration Fire Stops, or UL 1479, Standard for
Fire Tests of Through-Penetration Firestops.
1505.0 Combustible Piping Installations.
1505.1 Combustible piping installations shall be protected in
accordance with the appropriate fire resistance rating re-
quirements in the Building Code that list the acceptable area,
height, and type of construction for use in specific occupan-
cies to assure compliance and integrity of the fire resistance
rating prescribed.
1505.2 When penetrating a fire-resistance-rated wall, parti-
tion, floor, floor-ceiling assembly, roof-ceiling assembly, or
shaft enclosure, the fire resistance rating of the assembly shall
be restored to its original rating.
1505.3 Penetrations shall be protected by an approved pene-
tration firestop system installed as tested in accordance with
ASTM E 1 19, Standard for Fire Tests of Building Construction
and Materials, ASTM E 814, Standard for Fire Tests of
Through-Penetration Fire Stops, UL 263, Standard for Fire
Tests of Building Construction and Materials, or UL 1479,
Standard for Fire Tests of Through-Penetration Firestops, with
a positive pressure differential of not less than one- one-hun-
dredth (0.01) of an inch of water. Systems shall have an F rat-
ing of not less than one (1) hour but not less than the required
fire resistance rating of the assembly being penetrated. Sys-
tems protecting floor penetrations shall have a T rating of not
less than one (I) hour but not less than the required fire re-
sistance ratmg of the floor being penetrated. Floor penetra-
tions contained within the cavity of a wall at the location of the
floor penetration do not require a T rating. No T rating shall be
required for floor penetrations by piping that is not in direct
contact with combustible material.
1505.4 When piping penetrates a rated assembly, combustible
piping shall not connect to non-combustible piping unless it
can be demonstrated that the transition complies with the re-
quirements of Section 1505.3.
1505.5 Insulation and Coverings. Insulation and coverings
on or in the penetrating item shall not be permitted unless the
specific insulating or covering material has been tested as part
of the penetrating firestop system.
1505.6 Sleeves. Where sleeves are used, the sleeves should be
securely fastened to the fire-resistance-rated assembly. The
(inside) annular space between the sleeve and the penetrating
item and the (outside) annular space between the sleeve and
the fire-resistance-rated assembly shall be firestopped in ac-
cordance with the requirements for a sleeve penetrating item.
1506.0 Non-Combustible Piping Installations.
1506.1 Noncombustible piping installations shall be protected
in accordance with the appropriate fire resistance rating re-
quirements in the Building Code that list the acceptable area,
height, and type of construction for use in specific occupan-
cies to ensure compliance and integrity of the fire-resistance
rating prescribed.
1506.2 When penetrating a fire-resistance-rated wall, parti-
tion, floor, floor-ceiling assembly, roof-ceiling assembly, or
shaft enclosure, the fire-resistance rating of the assembly shall
be restored to its original rating.
Exceptions:
(1) Concrete, mortar, or grout shall be permitted to be used
to fill the annular spaces around cast-iron, copper, or steel
piping that penetrates concrete or masonry fire-resistant-
rated assemblies. The nominal diameter of the penetrat-

Part I [HCD 1]
Intent
This part is applicable to occupancies under the author-
ity of the Department of Housing and Community Develop-
ment as specified in Section 1.8.2.1.1 and is intended to:
L Conserve water by facilitating greater reuse of laundry,
shower, lavatory, and similar sources of discharge for ir-
rigation and/or indoor use.
2. Reduce the number of non-compliant graywater systems
by making legal compliance easily achievable.
3. Provide guidance for avoiding potentially unhealthful
conditions.
4. Provide an alternative way to relieve stress on a private
sewage disposal system by diverting the graywater
1601^.0 Graywater Systems - General.
(A) Except as otherwise provided for in this chapter, the pro-
visions of this code shall be applicable to graywater in-
stallation. The provisions of this part shall apply to the
construction, alteration, discharge, use, and repair of
graywater systems. The graywater system shall not be
connected to any potable water system without an air
gap or other physical device which prevents backflow
and shall not cause the ponding or runoff of graywater
A city, county, or city and county or other local govern-
ment may, after a public hearing and enactment of an or-
dinance or resolution, further restrict or prohibit the use
of graywater systems. For additional information, see
Health and Safety Code Section 18941. 7.
(B) The type of system shall be determined by the location,
discharge capacity, soil type, and ground water level.
The system shall be designed to handle graywater dis-
charged from the building and may include tank(s) and
other appurtenances necessary to ensure proper function
of the system.
Note: It is not the intent of this section to require that all
graywater must be handled by an irrigation field or dis-
posal field. It is acceptable for excess graywater to be
diverted to the building sewer through the overflow re-
quired pursuant to Section 1609A.0(E)
(C) No graywater system or part thereof shall be located on any
lot other than the lot that is the site of the building or struc-
ture that discharges the graywater, nor shall any graywater
system or part thereof be located at any point having less
than the minimum distances indicated in Table \6A-\.
Exception: When there exists a lawfully recorded perpet-
ual and exclusive covenant to an easement appurtenant and
right-of-way between adjoining land-owners of two or more
contiguous lots to discharge graywater fi^om one lot to an
adjoining lot
(D) No construction permit for any graywater system shall be II
issued until a plot plan with appropriate data satisfactory
to the Enforcing Agency has been submitted and approved. ||
When there is insufficient lot area or inappropriate soil con-
ditions to prevent the ponding or runoff of the graywater, as
determined by the Enforcing Agency, no graywater system
shall be allowed.
Exception: A construction permit shall not be required for
a clothes washer system which does not require cutting of
the existing plumbing piping provided it is in compliance
with Section 1603 A. 1.1.
(E) All graywater systems shall be designed to allow the user
to direct the flow to either the irrigation or disposal field
or the building sewer The means of changing the direc-
tion of the graywater shall be clearly labeled and read-
ily accessible to the user
(F) Water used to wash diapers or similarly soiled or infec-
tious garments or other prohibited contents shall be di-
verted by the user to the building sewer
(G) Graywater shall not be used in spray irrigation, allowed
to pond or runoff and shall not be discharged directly
into or reach any storm sewer system or any surface body
of water.
(H) Human contact with graywater or the soil irrigated by
graywater shall be minimized and avoided, except as re-
quired to maintain the graywater system. The discharge
point of any graywater irrigation or disposal field shall
be covered by at least (2) inches (51 mm) of mulch, rock,
or soil, or a solid shield to minimize the possibility of
human contact.
(I) Graywater shall not be used to irrigate root crops or ed-
ible parts of food crops that touch the soil.

purveyor, or by other arrangements acceptable to the Au-
thority Having Jurisdiction.
1620^.0 Inspection and Testing.
I (A) Recycled water piping shall be inspected and tested as
outlined in this code for testing of potable water piping.
(B) The recycled water system shall be inspected and tested
in accordance to the following: (a) an initial cross-con-
nection test before the initial operation of the recycled
water system; (b) an annual visual system inspection; (c)
a cross-connection test as required pursuant to Section
60316(a), Title 22, California Code of Regulations; (d) a
cross-connection test when there is material reason to
believe that the potable water and/or recycled water sys-
tem separation has been compromised; and (e) a cross-
connection test following remediation of a discovered
cross-connection. A material reason to believe that the
system has been compromised may be based on, but is
not limited to, evidence gathered: (a) during a visual in-
spection performed pursuant to Section 1620A.0, or (b)
as a result of an inspection performed following com-
plaints of water quality or flow conditions consistent with
a compromised system.
An initial Cross-Connection Test and subsequent
Annual Visual System Inspection shall be performed as
follows:
(1) Annual Visual System Inspection. A visual system 11
inspection shall be conducted annually by the Au- 1|
thority Having Jurisdiction or other authorities hav-
ing jurisdiction.
(i) Meter locations of the recycled water and||
potable water lines shall be checked to verify
that no modifications were made, and that no
cross-connections are visible.
(ii) All pumps and equipment, equipment room
signs, and exposed piping in the equipment
room shall be checked.
(iii) All valves shall be checked to ensure that valve
lock seals are still in place and intact. All valve
control door signs shall be checked to verify
that no signs have been removed.
(iv) If the visual inspection indicates that the recy-
cled water plumbing has been modified, a
Cross-Connection Test is required.
(2) Cross-Connection Test. The applicant shall per-
form the Cross-Connection Test as required pur-
suant to the first paragraph in Section 1 62 OA. 0(B).
The test shall be conducted in the presence of
the Authority Having Jurisdiction or other authori-
ties having jurisdiction to determine whether a
cross-connection occurred.
Alternate inspection and testing requirements
may be allowed by the Authority Having Jurisdic-
tion for residential, institutional, or industrial build-
ings where shutting off the water is not practical.
The recycled water purveyor or other designated ap-
pointee may substitute for the Authority Having Ju-
risdiction in the above mentioned inspection and
tests.
(i) The potable water system shall be activated and
pressurized. The recycled wdX^r system shall be
shut down and completely depressurized.
(ii) The potable water system shall remain pressur-
ized while the recycled water system is depres-
surized. The minimum period the recycled
water system is to remain depressurized shall
308
2010 CALIFORNIA PLUMBING CODE
NON-POTABLE WATER REUSE SYSTEMS
be determined on a case-by-case basis, taking
into account the size and complexity of the
potable and recycled water distribution systems.
(iii) All fixtures, potable and recycled, shall be tested
and inspected for flow. Flow from any recycled
water system outlet shall indicate a cross-con-
nection. No flow from a potable water outlet
would indicate that it may be connected to the
recycled water system.
(iv) The drain on the recycled water system shall be
checked for flow during the test and at the end
of the period.
(v) The potable water system shall then be com-
pletely depressurized.
(vi) The recycled water system shall then be acti-
vated and pressurized. For the initial test, a tem-
porary connection to a potable water supply
will be required to test the recycled water sys-
tem plumbing. At the conclusion of the test, the
temporary connection to the potable water sup-
ply shall be disconnected.
(vii)The recycled water system shall remain pres-
surized while the potable water system is de-
pressurized. The minimum period the potable
water system is to remain depressurized shall
II be determined on a case-by-case basis.
II (viii)^// fixtures, potable and recycled, shall be tested
and inspected for flow. Flow from any potable
water system outlet shall indicate a cross-con-
II nection. No flow from a recycled water outlet
would indicate that it is connected to the potable
water system.
(ix) The drain on the potable water system shall be
checked for flow during the test and at the end
of the period.
(x) If there is no flow detected in any of the fixtures
that would have indicated a cross-connection,
the potable water system shall be repressurized.
II (3) Cross-Connection Discovered. In the event that a
cross-connection is discovered, the following pro-
II cedure shall be activated immediately:
II (i) Recycled water piping to the building shall be
II shut down at the meter, and the recycled water
riser shall be drained,
(ii) Potable water piping to the building shall be
shut down at the meter,
(iii) The cross-connection shall be uncovered and
disconnected,
(iv) The building shall be retested following proce-
dures listed in Sections 1620^.0 (B)(1) and
(B)(2) above,
(v) The potable water system shall be chlorinated
with fifty (50) ppm chlorine for twenty-four
(24) hours,
(vi) The potable water system shall be flushed after
twenty-four (24) hours, and a standard bacterio-
logical test shall be performed. If test results are
acceptable, the potable water system shall be per-
mitted to be recharged.
Ahemate testing requirements may be allowed by the |||
Authority Having Jurisdiction. I

APPENDIX A
RECOMMENDED RULES FOR SIZING THE WATER SUPPLY SYSTEM
Because of the variable conditions encountered, it is imprac-
tical to lay down definite detailed rules of procedure for de-
termining the sizes of water supply pipes in an appendix,
which must necessarily be limited in length. For a more ade-
quate understanding of the problems involved, refer to Water-
Distributing Systems for Buildings, Report BMS 79 of the
National Bureau of Standards; and Plumbing Manual, Report
BMS 66, also published by the National Bureau of Standards.
The following is a suggested order of procedure for siz-
ing the water supply system.
A 1.0 Preliminary Information.
A 1.1 Obtain the necessary information regarding the mini-
mum daily service pressure in the area where the building is
to be located.
A 1.2 If the building supply is to be metered, obtain informa-
tion regarding friction loss relative to the rate of flow for me-
ters in the range of sizes likely to be used. Friction-loss data
can be obtained from most manufacturers of water meters.
Friction losses for disk-type meters shall be permitted to be
obtained from Chart A-1 .
A 1.3 Obtain all available local information regarding the use
of different kinds of pipe with respect both to durability and to
decrease in capacity with length of service in the particular
water supply.
A 2.0 Demand Load.
A 2.1 Estimate the supply demand for the building main, the
principal branches and risers of the system by totaling the fix-
ture units on each, Table A-2, and then by reading the corre-
sponding ordinate from Chart A-2 or A- 3, whichever is
applicable.
A 2.2 Estimate continuous supply demands in gallons per
minute (liters per second) for lawn sprinklers, air conditioners,
etc., and add the sum to the total demand for fixtures. The result
is the estimated supply demand of the building supply.
A 3.0 Permissible Friction Loss.
A 3.1 Decide what is the desirable minimum residual pres-
sure that shall be maintained at the highest fixture in the sup-
ply system. If the highest group of fixtures contains
flushometer valves, the residual pressure for the group shall
not be less than fifteen (15) psi (103 kPa). For flush tank sup-
plies, the available residual pressure shall not be less than
eight (8) psi (55 kPa).
A 3.2 Determine the elevation of the highest fixture or group
of fixtures above the water (street) main. Multiply this dif-
ference in elevation by forty- three hundredths (0.43). The re-
sult is the loss in static pressure in psi (pounds per square
inch) (kPa).
A 3.3 Subtract the sum of loss in static pressure and the resid-
ual pressure to be maintained at the highest fixture from the
average minimum daily service pressure. The result will be
the pressure available for friction loss in the supply pipes, if
no water meter is used. If a meter is to be installed, the fric-
tion loss in the meter for the estimated maximum demand
should also be subtracted from the service pressure to deter-
mine the pressure loss available for friction loss in the sup-
ply pipes.
A 3.4 Determine the developed length of pipe from the water
(street) main to the highest fixture. If close esfimates are de-
sired, compute with the aid of Table A-3, the equivalent
length of pipe for all fittings in the line from the water (street)
main to the highest fixture and add the sum to the developed
length. The pressure available for friction loss in pounds per
square inch (kPa), divided by the developed lengths of pipe
from the water (street) main to the highest fixture, times one-
hundred (100), will be the average permissible friction loss
per one-hundred (100) feet (30,480 mm) length of pipe.
A 4.0 Size of Building Supply.
A 4.1 Knowing the permissible friction loss per one-hundred
(100) feet (30,480 mm) of pipe and the total demand, the di-
ameter of the building supply pipe shall be permitted to be
obtained from Charts A-4, A-5, A-6, or A-7, whichever is ap-
plicable. The diameter of pipe on or next above the coordinate
point corresponding to the estimated total demand and the
permissible friction loss will be the size needed up to the first
branch from the building supply pipe.
A 4.2 If copper tubing or brass pipe is to be used for the sup-
ply piping and if the character of the water is such that only
slight changes in the hydraulic characteristics may be ex-
pected. Chart A-4 shall be permitted to be used. |
A 4.3 Chart A-5 should be used for ferrous pipe with only the
most favorable water supply in regards to corrosion and cak-
ing. If the water is hard or corrosive, Chart A-6 or A-7 will be
applicable. For extremely hard water, it will be advisable to
make additional allowances for the reduction of capacity of
hot- water lines in service.
A 5.0 Size of Principal Branches and Risers.
A 5.1 The required size of branches and risers shall be per- 1
mitted to be obtained in the same manner as the building sup- 1
ply, by obtaining the demand load on each branch or riser and
using the permissible friction loss computed in Section A 3.0.
A 5.2 Fixture branches to the building supply, if they are
sized for the same permissible friction loss per one-hun-
dred (100) feet (30,480 mm) of pipe as the branches and
risers to the highest level in the building, may lead to in-
adequate water supply to the upper floor of a building.
This may be controlled by (1) selecting the sizes of pipe
2010 CALIFORNIA PLUMBING CODE
315
RECOMMENDED RULES FOR SIZING THE WATER SUPPLY SYSTEM
for the different branches so that the total friction loss in
each lower branch is approximately equal to the total loss
in the riser, including both friction loss and loss in static
pressure; (2) throttling each such branch by means of a
valve until the preceding balance is obtained; (3) increas-
ing the size of the building supply and risers above the
minimum required to meet the maximum permissible fric-
tion loss.
A 5.3 The size of branches and mains serving flushometer
tanks shall be consistent with sizing procedures for flush tank
water closets.
A 6.0 GeneraL
A 6.1 Velocities shall not exceed ten (10) feet/second (3.0
m/sec.) or the maximum values given in the appropriate In-
stallation Standard, except as otherwise approved by the Au-
thority Having Jurisdiction.
A 6.2 If a pressure-reducing valve is used in the building sup-
ply, the developed length of supply piping and the permissi-
ble friction loss should be computed from the building side of
the valve.
A 6.3 The allowances in Table A-3 for fittings are based on
non-recessed threaded fittings. For recessed threaded fittings
and streamlined soldered fittings, one-half (Vi) of the al-
lowances given in the table will be ample.
A 7.0 Example.
A 7.1 Assume an office building of four (4) stories and base-
ment; pressure on the building side of the pressure-reducing
valve of fifty-five (55) psi (379 kPa) (after an allowance for
reduced pressure falloff at peak demand); an elevation of
highest fixture above the pressure-reducing valve of forty-
five (45) feet (13,716 mm); a developed length of pipe from
the pressure-reducing valve to the most distant fixture of
two-hundred (200) feet (60,960 mm); and fixtures to be in-
stalled with flush valves for water closets and stall urinals as
follows:
If the pipe material and water supply are such that Chart
A-5 applies, the required diameter of the building supply is
three and one-half (314) inches (88.9 mm) and the required di-
ameter of the branch to the hot- water heater is one and one-
half (1^2) inches (40 mm).
I The sizes of the various branches and risers shall be per-
mitted to be determined in the same manner as the size of the
building supply or the branch to the hot-water system, by es-
timating the demand for the riser or branch from Chart A-2 or
A-3 and applying the total demand estimate from the branch,
riser, or section thereof to the appropriate flowchart.

able for friction loss is found by the following:
55 ~ [15 + (45 X 0.43)] = 20.65 psi
Metric: 379 - [103.4 + (13.7 x 9.8)] = 142.3 kPa
The allowable friction loss per 100 feet (30.4 m) of pipe is therefore:
100x20.65 -200 =10.32 psi
Metric: 30.4 x 142.3 - 60.8 = 71.1 kPa

Notes:
Size of the cold branch pipe, or both the hot and cold branch pipes.
Apphances, Appurtenances, or Fixtures not included in this Table may be sized by reference to fixtures having a similar flow rate and frequency of use.
The hsted fixture unit values represent their total load on the cold water service. The separate cold water and hot water fixture unit value for fixtures having both
cold and hot water cormections may each be taken as three-quarters QA) of the listed total value of the fixture.
The listed minimum supply branch pipe sizes for individual fixtures are the nominal O^.D.) pipe size.
For fixtures or supply connections likely to impose continuous flow demands, determine the required flow in gallons per minute (GPM) and add it separately
to the demand (in GPM) for the distribution system or portions thereof
Assembly [Public Use (See Table 4-1)].
Reduced fixture unit loading for additional hose bibbs is to be used only when sizing total building demand and for pipe sizing when more than one (1) hose
bibb is supplied by a segment of water-distributing pipe. The fixture branch to each hose bibb shall be sized on the basis of two and one-half (2.5) fixture units.

APPENDIX B
EXPLANATORY NOTES ON COMBINATION WASTE AND VENT SYSTEMS
(See Section 910.0 of the California Plumbing Code for specific limitations)
B 1.0 Combination waste and vent systems, as outlined in
Section 910.0 of this code, cover the horizontal wet venting
of a series of traps by means of a common waste and vent
pipe. Pipe sizes at least two (2) pipe sizes larger than those re-
quired for a conventional system are designed to maintain a
wetted perimeter or flow line low enough in the waste pipe to
allow adequate air movement in the upper portion, thus bal-
ancing the system. Sinks, lavatories, and other fixtures that
rough in above the floor, should not be permitted on a com-
bination waste and vent system, which, at best, is merely an
expedient designed to be used in locations where it would be
structurally impractical to provide venting in the conventional
manner.
Combination waste and vent systems are intended pri-
marily for extensive floor or shower drain installations where
separate venting is not practical, for floor sinks in markets,
demonstration or work tables in school buildings, or for sim-
ilar applications where the fixtures are not adjacent to walls
or partitions. Due to its oversize characteristics, such a waste
system is not self-scouring and, consequently, care should be
exercised as to the type of fixtures connected thereto and to
the location of cleanouts. In view of its grease-producing po-
tential, restaurant kitchen equipment should not be connected
to a combination waste and vent system.
B 5.0 Duplicate layout drawings of each such proposed pip-
ing system must be presented to the Authority Having Juris-
diction and approval obtained before any installation is made.
Complicated layouts should be checked by qualified person-
nel.
B 5.1 Example of Sizing.
A floor drain normally requires a two (2) inch (50 mm) trap
and waste. On a combination waste and vent system, both trap
and waste must be increased two (2) pipe sizes (through 2V2"
and 3") (65 mm and 80 mm), which would make the trap
three (3) inches (80 mm). Pipe sizes recognized for this pur-
pose are 2 in., IVi in., 3 in., 31/2 in., 4 in., 4V2 in., 5 in., 6 in.,
etc. (50 mm, 65 mm, 80 mm, 90 mm, 100 mm, 115 mm, 125
mm, 150 mm, etc.). The tailpiece between the floor drain and
its trap should be two (2) inches (50 mm) (or normal size) to
ensure that the amount of wastewater entering the trap only
partially fills the waste branch. A three (3) inch (80 mm) floor
drain would thus require a four (4) inch (100 mm) trap, a four
(4) inch (100 mm) floor drain, and five (5) inch (125 mm)
trap, etc., for the reasons previously stated.
WHEN ESf DOUBT, CHECK WITH YOUR LOCAL Au-
thority Having Jurisdiction.
B 2.0 Caution must be exercised to exclude appurtenances
delivering large quantities or surges of water (such as pumps,
sand interceptors, etc.) from combination waste and vent sys-
tems in order that adequate venting will be maintained. Small
fixtures with a waste-producing potential of less than seven
and one-half (7 V2) gallons per minute (28.4 L/min.) shall be
permitted to be safely assigned a loading value of one (1) unit.
Long runs should be laid at the minimum permissible slope in
order to keep tailpieces as short as possible. Tailpieces should
not exceed two (2) feet (610 mm) in length, which may ne-
cessitate slopes up to forty-five (45) degrees (0.79 rad) (see
definition of horizontal pipe) on some branches.
B 3.0 It is essential that the pneumatics of such a system be
properly engineered, as the air pressure within the line must
at all times balance that of outside atmosphere in order to pre-
vent either trap seal loss or air locking between traps. Long
mains shall be provided with additional relief vents located at
intervals not exceeding one-hundred (100) feet (30,480 mm).
Each such relief vent should equal at least one-half (!/2) of the
inside cross-sectional area of the drain pipe served.
B 4.0 Trap sizes are required to be equivalent to the branches
they serve (two (2) pipe sizes larger than normal), and tail-
pieces between fixtures or floor drains and such traps should
be reduced to normal size.

APPENDIX D
SIZING STORM WATER DRAINAGE SYSTEMS
D 1.0 Roof Drainage.
The rainfall rates in Table D-1 should be used for design un-
less higher values are established locally.
D2.0 Sizing by Flow Rate.
Storm drainage systems can be sized by storm water flow rates,
using the appropriate GPM/square foot of rainfall listed in Table
D-1 for the local area. Multiplying the listed GPM/square foot
by the roof area being drained by each inlet (in square feet) pro-
duces the gallons per minute (GPM) of required flow for sizing
each drain inlet. The flow rates (GPM) can then be added to de-
termine the flows in each section of the drainage system. Re-
quired pipe sizes for various flow rates (GPM) are listed in Table
11-1 and Table 11-2.
D 3.0 Sizing by Roof Area.
Storm drainage systems can be sized using the roof area served
by each section of the drainage system. Maximum allowable
roof areas with various rainfall rates are listed in Table 11-1
and Table 11-2, along with the required pipe sizes. Using this
method, it may be necessary to interpolate between two listed
rainfall rate columns (inches per hour). To determine the al-
lowable roof area for a listed pipe size at a listed slope, divide
the allowable square feet of roof for a one (1) in./hr. (25.4
mm/h) rainfall rate by the listed rainfall rate for the local area.
For example, the allowable roof area for a six (6) inch (150
mm) drain at one-eighth (Vs) inch (3.2 mm) slope with a rain-
fall rate of 3.2 inches (81 mm/h) is 21,400/3.2 = 6,688 square
feet (621.3 m2).
D 4.0 Capacity of Rectangular Scuppers.
Table D-2 lists the discharge capacity of rectangular roof
scuppers of various widths with various heads of water. The
maximum allowable level of water on the roof should be ob-
tained from the structural engineer, based on the design of the
roof
TABLE D-1
MAXIMUM RATES OF RAINFALL FOR VARIOUS CITIES
The rainfall rates in this table are based on U.S. Weather Bureau
Technical Paper No. 40, Chart 14: 100-Year 60-Minute Rainfall (inches).

Community Development as specified in Section 1.8.2.1 .1 .
G LO Graywater Systems (General).
(a) The provisions of this Appendix shall apply to the con-
str-uction, installation, alteration and repair ofgraywater
systems for subsurface landscape irrigation. The graywa-
ter system shall not be connected to any potable water sys-
tem without an air gap (a space or other physical device
which prevents backflow) and shall not result in any sur-
facing of the graywater. Except as otherwise provided for
in this Appendix, the provisions of the California Plumbing
Code (CRC) shall be applicable to graywater installa-
tions.
(b) The type of system shall be determined on the basis of lo-
cation, soil type and ground water level and shall be de-
signed to accept all graywater connected to the system from
the building. The system shall discharge into subsurface ir-
rigation fields and may include surge tank(s) and appurte-
nances, as required by the Administrative Authority.
(c) No graywater system, or part thereof shall be located on
any lot other than the lot which is the site of the building
or structure which discharges the graywater; nor shall any
graywater system or part thereof be located at any point
having less than the minimum distances indicated in Table
G~L
(d) No permit for any graywater system shall be issued until
a plot plan with appropriate data satisfactory to the Ad-
ministrative Authority has been submitted and approved.
When there is insufficient lot area or inappropriate soil
conditions for adequate absorption of the graywater, as
determined by the Administrative Authority, no graywater
system shall be permitted. The Administrative Authority is
a city or county.
(e) No permit shall be issued for a graywater system which
would adversely impact a geologically sensitive area, as
determined by the Administrative Authority.
(f) Private sewage disposal systems existing or to be con-
structed on the premises shall comply with Appendix K of
this Code or applicable local ordinance. When abandoning
underground tanks, Section 722.0 of the CRC shall apply.
Also, appropriate clearances from graywater systems shall
be maintained as provided in Table G-L The capacity of
the private sewage disposal system, including required fu-
ture areas, shall not be decreased by the existence or pro-
posed installation of a graywater system servicing the
premises.
(g) Installers ofgraywater systems shall provide an operation
and maintenance manual, acceptable to the Administra-
tive Authority, to the owner of each system. Graywater sys-
tems require regular or periodic maintenance.
(h) The Administrative Authority shall provide the applicant
a copy of this Appendix.
G 2,0 Definitions,
Graywater is untreated waste water which has not come into
contact with toilet waste. Graywater includes used water from
bathtubs, showers, bathroom wash basins, clothes washing
machines and laundry tubs or an equivalent discharge as ap-
proved by the Administrative Authority. It does not include
waste water from kitchen sinks, photo lab sinks, dishwashers
or laundry water from soiled diapers.
Surfacing ofgraywater means the ponding, running off
or other release of graywater from the land surface.
G 3.0 Permit
It shall be unlawful for any person to construct, install or
alter, or cause to be constructed, installed or altered, any
graywater system in a building or on a premises without first
obtaining a permit to do such work from the Administrative
Authority.
G 4.0 Drawings and Specifications.
The Administrative Authority may require any or all of the
following information to be included with or in the plot plan
before a permit is issued for a graywater system:
(a) Plot plan drawn to scale completely dimensioned, show-
ing lot lines and structures, direction and approximate
slope of surface, location of all present or proposed re-
taining walls, drainage channels, water supply lines, wells,
paved areas and structures on the plot, number of bed-
rooms and plumbing fixtures in each structure, location of
private sewage disposal system and 1 00 percent expansion
area or building sewer connecting to public sewer, and lo-
cation of the proposed graywater system.
(b) Details of construction necessary to ensure compliance
with the requirements of this Appendix together with a
full description of the complete installation, including in-
stallation methods, construction and materials as re-
quired by the Administrative Authority.
(c) A log of soil formations and ground water level as deter-
mined by test holes dug in close proximity to any proposed
irrigation area, together with a statement of water ab-
sorption characteristics of the soil at the proposed site as
determined by approved percolation tests. In lieu of per-
colation tests, the Administrative Authority may allow the
use of Table G-2, an infiltration rate designated by the
Administrative Authority, or an infiltration rate deter-
mined by a test approved by the Administrative Authority.

line prior to and during inspection. All seams and
joints shall be left exposed and the tank shall remain
watertight.
(2) A flow test shall be performed through the system to
the point of graywater irrigation. All lines and com-
ponents shall be watertight.
G 6.0 Procedure for Estimating Graywater Discharge.
(a) Single Fam ily Dwellings and Multifam ily Dwellings.
The Administrative Authority may utilize the graywater
discharge procedure listed below, water use records, or
calculations of local daily per person interior water use:
1 . The number of occupants of each dwelling unit shall
be calculated as follows:
First bedroom 2 occupants
Each additional bedroom 1 occupant
2. The estimated graywater flows for each occupant
shall be calculated as follows:
Showers, bathtubs, and wash basins 25 GPD/occupant
Laundry 15 GPD/occupant
3. The total number of occupants shall be multiplied
by the applicable estimated graywater discharge as
provided above and the type of fixtures connected to
the graywater system.
(b) Commercial, Industrial, and Institutional Projects.
The Administrative Authority may utilize the graywater
discharge procedure listed below, water use records or
other documentation to estimate graywater discharge:
L The square footage of the building divided by the oc-
cupant load factor from U.B.C. Table 10-A equals
the number of occupants.
2. The number of occupants times the flow rate per
person (minus toilet water and other disallowed
sources) from C.P.C. Table 1-2 equals the estimated
graywater discharge per day.
The graywater system shall be designed to distribute the
total amount of estimated graywater discharged daily.
G 7.0 Required Area of Subsurface Irrigation.
Each irrigation zone shall have a minimum effective irriga-
tion area for the type of soil and infiltration rate to distribute
all graywater produced daily, pursuant to Section G 6.0, with-
out surfacing. The required irrigation area shall be based on
the estimated graywater discharge, pursuant to Section G 6.0
of this Appendix, size of surge tank, or a method determined by
the Administrative Authority.
If the mini-leachfield irrigation system is used, the re-
quired square footage shall be determined from Table G-2, or
equivalent, for the type of soil found in the excavation. The area
of the irrigation field shall be equal to the aggregate length of
the perforated pipe sections within the irrigation zone times
the width of the proposed mini-leachfield trench.
No irrigation point shall be within 5 vertical feet (1524
mm) of highest known seasonal groundwater nor where gray-
water may contaminate the ground water or ocean water The
applicant shall supply evidence of ground water depth to the
satisfaction of the Administrative Authority,
G 8.0 Determination of Irrigation Capacity.
(a) In order to determine the absorption quantities of ques-
tionable soils other than those listed in Table G-2, the pro-
posed site may be subjected to percolation tests acceptable
to the Administrative Authority or determined by the Ad-
ministrative Authority.
(b) When a percolation test is required, no mini-leachfield sys-
tem or subsurface drip irrigation system shall be permit-
ted if the test shows the absorption capacity of the soil is
less than 60 minutes/inch or more rapid than five min-
utes/inch, unless otherwise permitted by the Administrative
Authority.
(c) The irrigation field size may be computed from Table G-2,
or determined by the Administrative Authority or a de-
signee of the Administrative Authority.
G 9.0 Surge Tank Construction (Figure I).
(a) Plans for surge tanks shall be submitted to the Adminis-
trative Authority for approval. The plans shall show the
data required by the Administrative Authority and may
include dimensions, structural calculations, and bracing
details.
(b) Surge tanks shall be constructed of solid, durable mate-
rials, not subject to excessive corrosion or decay, and
shall be watertight

gation systems follow :
(a) Standards for a subsurface drip irrigation system are:
(1) Minimum 140 mesh (115 micron) filter with a capac-
ity of 25 gallons (94,6 L) per minute, or equivalent,
filtration, sized approximately to maintain the filtra-
tion rate, shall be used. The filter backwash and flush
discharge shall be caught, contained and disposed of
to the sewer system, septic tank or, with approval of
the Administrative Authority, a separate mini-leach-
field sized to accept all the backwash and flush dis-
charge water Filter backwash water and flush water
shall not be used for any purpose. Sanitary proce-
dures shall be followed when handling filter back-
wash and flush discharge or graywater.

less than the number of emitters specified in Table G-
3, or through a procedure designated by the Adminis-
trative Authority. Minimum spacing between emitters
is 14 inches (356 mm) in any direction.
(4) The system design shall provide user controls, such as
valves, switches, timers and other controllers, as ap-
propriate, to rotate the distribution of graywater be-
tween irrigation zones.
(5) All drip irrigation supply lines shall be polyethylene
tubing or PVC Class 200 pipe or better and Schedule
40 fittings. All joints shall be properly solvent-ce-
mented, inspected and pressure tested at 40 psi (276

2.2 Type of Joints.
2.2.1 General Information.
Copper tube and fittings may be joined in a num-
ber of ways, depending on the purpose of the sys-
tem. Soldering and brazing with capillary fittings
are the methods used most.
The American Welding Society (AWS) defmes sol-
dering as a joining process which takes place below
840 °F (449 °C) and brazing as a similar process
which occurs above 840°F (449^C) but below the
melting point of the base metals. In actual practice
for copper systems, most soldering is done at tem-
peratures from about 350°F (177'^C) to 550^F
(288°C), while most brazing is done at tempera-
tures ranging from llOO^F (593°C) to 1500°F
(816°C). The choice between soldering or brazing
will generally depend on operating conditions. Sol-
der joints are generally used where the service tem-
perature does not exceed 250''F (121°C), while
brazed joints are used where greater tensile strength
is required to resist vibration, or pressure or tem-
perature cycling, or where system temperatures are
as high as 350°F (UTC). Although brazed joints
offer higher joint strength in general, the annealing
of the tube and fitting which results from the higher
heat used in the brazing process can cause the rated
pressure of the system to be less than that of a sol-
dered joint. This fact should also be considered in
choosing which joining process to use.
Mechanical joints are used frequently for some
underground connections, for joints where the use
of heat is impractical and for joints that may have
to be disconnected from time to time. [UPC
316.1]
2.2.2 Fittings for Soldered, Brazed, and Mechanical
Joints.
Cast fittings are available in all standard tube sizes
and in a wide variety of types to cover needs for
plumbing. They can be either soldered or brazed,
2.2.3
although brazing cast fittings requires care.
Wrought copper pressure fittings are also available
over a wide range of sizes and types. These, too,
can be joined by either soldering or brazing and
wrought fittings are preferred where brazing is the
joining method. Otherwise, the choice between
cast and wrought fittings is largely a matter of the
user's preference and availability. According to the
American Welding Society, the strength of a
brazed joint will meet or exceed that of the tube
and fitting being joined when the joint overlap and
the depth of the filler metal penetration is a mini-
mum of three times the thickness of the thinner
base metals (tube or fitting) and a well-developed
fillet (cap) is present. The strength of a brazed cop-
per tube joint does not vary much with different
filler metals but depends on maintaining the
proper clearance between the outside of the tube
and the socket (cup) of the fitting. Copper tube and
solder-type pressure fittings are accurately made
for each other, and the tolerances permitted for
each assure the capillary space will be within the
limits necessary for a joint of satisfactory strength.
However, the depths of the socket are considerable
deeper than the three times required by AWS.
There are standards available for the manufacture
of fittings made specifically for brazing, these in-
clude ASME B 16.50 and MSS SP 73. When fit-
tings are made to these standards, they cannot be
soldered. They must be brazed.
2.2.2.1 Mechanical Joints.
Flared-tube fittings provide metal-to-metal con-
tact similar to ground joint unions; both can be
easily taken apart and reassembled. Grooved end
mechanical fittings are also available in sizes 2-
inches to 6-inches. Mechanical joint fittings are
especially usefril where residual water cannot be
removed from the tube and soldering is difficult.
Mechanical joints may be required where a fire
hazard exists and the use of a torch to make sol-
dered or brazed joints is not allowed. Also, sol-
dering under wet conditions can be very difficult
and mechanical joints may be preferred under
such circumstances. [UPC 316.0]
Solders.
Most solders referenced in ASTM B 32 can be
used to join copper tube and fittings in potable
water systems.
Note: Users of the Uniform Plumbing Code are
reminded that provisions of the Federal Safe
Drinking Water Act of 1986 (SDWA), which all
must obey, forbid the use of solder which contains
in excess of 0. 2% of lead, in potable water sys-
tems. The provisions of the act are incorporated in
all ordinances, statutes, state and municipal reg-
ulations by reference and by operation of law,
[UPC 316.0]

2.2.4
The selection of a solder depends on the operating
pressure and temperature of the system. Consid-
eration should also be given to the stresses on the
joint caused by thermal expansion and contrac-
tion. However, stresses due to temperature
changes should not be significant in two com-
monly encountered cases: when tube lengths are
short, or when expansion loops are used in long
tube runs.
Solder is generally used in wire form, but paste-
type solders are also available. These are finely
granulated solders in suspension in a paste flux.
These solder/flux pastes must meet the require-
ments of ASTM B 813. When using paste-type
solders, observe these four rules:
1 . Wire solder must be applied in addition to the
paste to fill the voids and assist in displacing
the flux, otherwise the surfaces may be well
"tinned" and yet there may not be a good joint
with a continuous bond. Use the same type of
solder (e.g., 50-50 or 95-5) as that used in the
paste.
2. The paste mixture must be thoroughly stirred
if it has been standing in the can for more
than a very short time, as the solder has a ten-
dency to settle rapidly to the bottom.
3. The flux cannot be depended on to clean the
tube. Cleaning should be done manually as is
recommended for any other flux and solder.
4. Remove any excess flux.
Solders are available that contain small amounts
of silver or other additives to impart special prop-
erties. Such solders may require special fluxes.
The manufacturer's recommendations should be
consulted regarding proper procedures and fluxes
for such solders and about the expected proper-
ties.
Soldering Flux.
The functions of the soldering flux are to remove
residual traces of oxides, to promote wetting and
to protect the surfaces to be soldered from oxida-
tion during heating. The flux should be applied to
clean surfaces and only enough should be used to
lightly coat the areas to be joined.
An oxide film may reform quickly on copper after
it has been cleaned. Therefore, the flux should be
applied as soon as possible after cleaning,
CAUTION
Careless workmanship, especially during flux ap-
plications, can result in corrosion of the tube long
after the system has been installed. If excessive
flux is used, the residue inside the tube can cause
corrosion. In an extreme case, such residual flux
can actually lead to perforation through the tube
wall causing leakage. To guard against this dan-
ger, it is important (1) to choose a flux that is man-
ufactured to ASTM B 813, and (2) to use only the
minimum amount actually needed to make the
joint.
2.3 Solder Joints.
2.3.1 Soldering and brazing both involve basic steps,
based on ASTM Standard Practice B 828, which
must be executed with care and craftsmanship.
The steps are:
(1) Measuring
(2) Cutting
(3) Reaming
(4) Cleaning
(5) Fluxing
(6) Assembly and support
(7) Heating
(8) Applying the filler metal
(9) Cooling and cleaning
Each step contributes to a strong, dependable joint.
2.3.2 Measuring.
Measuring the length of each tube segment must
be accurate. Inaccuracy can compromise joint
quality. If the tube is too short it will not reach all
the way into the socket of the fitting and a proper
joint cannot be made. If the tube segment is too
long there is a danger of cocking the tube in the
fitting and putting strain on the system which
could affect service life,
2.3.3 Cutting.
Once the tube is measured, it can be cut. Cutting
can be accomplished in a number of different
ways to produce a satisfactory square end. The
tube can be cut with a disc-type tube cutter, a
hacksaw, an abrasive wheel, or with a stationary
or portable handsaw. Care must be taken that the
tube is not deformed while being cut. Regardless
of the method, the cut must be square with the run
of the tube so that the tube will seat properly in
the fitting socket.
2.3.4 Reaming.
All pipe and tube shall be reamed to the full I.D.
of the pipe and tube to remove the small burr cre-
ated by the cutting operation. If this rough, inside
edge is not removed erosion-corrosion may occur
due to locaUzed turbulence and high velocity.
Tools used to ream tube ends include the reaming
blade on the tube cutter, half-round or round files,
a pocket knife, or a suitable deburring tool. With
annealed tube, care must be taken not to deform
the tube end by applying too much pressure. Both
the inside and the outside of the tube may require
removal of the burr, especially in large diameters.

COPPER PLUMBING TUBE, PIPE, AND FITTINGS
2.3.5 Cleaning.
The removal of all oxides and surfaces soil is cru-
cial if filler metal is to flow properly into the joint.
Failure to remove them can interfere with capil-
lary action and may lessen the strength of the joint
and cause failure.
Mechanical cleaning is a simple operation. The
end of the tube should be lightly abraded using
sand cloth or nylon abrasive pads for a distance
only slightly more than the depth of the fitting
socket. The socket of the fitting should also be
cleaned using sand cloth, abrasive pads, or a prop-
erly sized fitting brush.
Copper is a relatively soft metal. If too much ma-
terial is removed, a loose fit will resuh and inter-
fere with satisfactory capillary action in making the
joint. The capillary space between tube and fitting
is approxunately 0.004 inch (O.IO mm). Solder or
brazing filler metal can fill this gap by capillary ac-
tion. This spacing is critical for the filler metal to
flow into the gap and form a strong joint.
Surfaces once cleaned should not be touched with
bare hands or oily gloves. Skin oils, lubricating
oils, and grease impair filler metal flow and wet-
ting.
2.3.6 Fluxing.
Stir the flux before use. Flux will dissolve and re-
move traces of oxide fi-om the cleaned surfaces to
be joined, protect the cleaned surfaces fi*om reox-
idation during heating, and promote wetting of the
surfaces by the solder. A thin, even coating of flux
should be applied with a brush to both tube and
fitting as soon as possible after cleaning. Do not
apply with fingers. Chemicals in the flux can be
harmful if carried to the eyes, mouth, or open cuts.
2.3.7 Assembly and Support.
After both tube and fitting surfaces are properly
fluxed, they should be assembled, making sure the
tube seats against the base of the fitting socket. A
slight twisting motion ensures even distribution
by the flux. Remove any excess flux. Care must
be taken to assure that the tube and fittings are
properly supported to ensure a uniform capillary
space around the entire circumference of the joint.
Uniformity of capillary space will ensure good
filler metal penetration if the guidelines of suc-
cessful joint making are followed. Excessive joint
clearance can cause the filler metal to crack under
stress or vibration.
The joint is now ready for soldering. Joints pre-
pared and ready for soldering should be completed
the same day and not left unfinished overnight.
2.3.8 Heating.
WARNING: When dealing with an open flame,
high temperatures, and flammable gases, safety
2.3.9
2.3.10
precautions must be observed as described in the
ANSI /ASC Z49. 1 Standard.
Heat is generally applied using an air/fuel torch.
Such torches use acetylene or an LP gas. Electric
resistance tools can also be used.
Begin heating with the flame perpendicular to the
tube on the bottom. The copper tube conducts the
initial heat into the fitting socket for even distri-
bution of heat in the joint area. The extent of this
preheating depends upon the size of the joint. Ex-
perience will indicate the amount of time needed.
Preheating of the assembly should include the en-
tire circumference of the tube in order to bring the
entire assembly up to a suitable preheat condition.
However, for joints in the horizontal posifion,
avoid directly preheating the top of the joint to
avoid burning the soldering flux. The natural ten-
dency of heat to rise will ensure adequate preheat
of the top of the assembly. Next, move the flame
onto the fitting socket. Sweep the flame aher-
nately fi*om the fitting socket back onto the tube a
distance equal to the depth of the fitting socket.
Touch the solder to the joint. If the solder does not
melt, remove it and continue the heating process.
Be careful not to overheat or to direct the flame
into the fitting cup. This could cause the flux to
bum and destroy its effectiveness. When the sol-
der begins to melt, the heat should be directed to
the base of the cup to aid capillary action in draw-
ing the molten solder into the fitting socket to-
wards the heat source.
Applying the Filler Metal.
For joints in the horizontal position, start apply-
ing the solder slightly off-center at the bottom of
the joint. When the solder metal begins to melt
from the heat of the tube and fitting do not use the
torch to meh the solder; push the solder straight
into the joint while keeping the torch at the base of
the fitting socket and slightly ahead of the point
of application of the solder. Continue this tech-
nique across the bottom of the fitting and up the
side to the top of the fitting. Return to the begin-
ning, overlapping slightly by re-melting the sol-
der at the point and proceed up the other side to
the top, again overlapping slightly.
For joints in the vertical position, a similar se-
quence of overlapping passes should be made,
starting wherever is convenient. Molten solder
will be drawn into the joint by capillary action re-
gardless of whether the solder is being fed up-
ward, downward or horizontally. IMPORTANT:
Always remember to let the heat lead the alloy.
Do not apply the filler metal in front of the heat.
Cooling and Cleaning.
After the joint has been completed, natural cool-
ing is best. Shock cooling with water may cause
374
2010 CALIFORNIA PLUMBING CODE
COPPER PLUMBING TUBE, PIPE, AND FITTINGS
unnecessary stress on the joint and result in even-
tual failure. When cool, clean off any remaining
flux with a wet rag.
2.3.11 Testing.
Test all completed assemblies for joint integrity
following the procedures described in the body of
this code. Completed systems should be flushed
to remove excess flux and debris as soon as pos-
sible after completion.
2.4 Brazed Joints.
2.4.1 Brazing is another commonly used method for
joining copper tube. Making brazed joints is sim-
ilar to making soldered joints with respect to
measuring, cutting, reaming, cleaning, assembly,
and support. And as in soldering, the brazing filler
metal is melted by the heat of the tube and fitting
and drawn into the joint by capillary action.
The major differences between soldering and
brazing are the:
• Type of flux used;
• Composition of filler metal; and
• Amount of heat required to melt the filler metal.
2.4.2 Brazing Flux.
The fluxes used for brazing copper joints are dif-
ferent in composition from soldering fluxes. The
two types cannot be used interchangeably. Unlike
soldering fluxes, brazing fluxes are water based.
Similar to soldering fluxes, brazing fluxes dis-
solve and remove residual oxide from the metal
surfaces, protect the metal from reoxidation dur-
ing heating and promote wetting of the surfaces
to be joined by the brazing filler metal.
Fluxes also provide the craftsman with an indica-
tion of temperature. Application of the flux is the
same as when soldering. If the outside of the fit-
ting and the heat-affected area of the tube are cov-
ered with flux (in addition to the end of the tube
and the cup), oxidation will be prevented and the
appearance of the joint will be greatly improved.
2.4.3 Brazing Filler Metals.
Brazing filler metals suitable for joining copper
tube systems are of two classes. Classified ac-
cording to their components, they are: BCuP
(Brazing-Copper-Phosphorus) and BAg (Brazing-
Silver).
BCuP filler metals are preferred for joining copper
tube and fittings if codes and construction speci-
fications allow it. The phosphorus in them acts as
a fluxing agent and the lower percentage of silver
makes them relatively low cost. When using cop-
per tube, wrought copper fittings, and BCuP braz-
ing filler metal, fluxing is optional. However,
when cast fittings are brazed, flux must be used.
2.4.4 Heating.
WARNING: When dealing with an open flame,
high temperatures, and flammable gases, safety
precautions must be observed as described in the
ANSI/ASC Z49.1 Standard. Oxy/fiiel torches are
generally used for brazing because of their higher
temperatures. However, recent innovations in tip
design make air/fijel torches usefiil for brazing on
a wide range of sizes for brazing.
The heating operation is the same as for solder-
ing. Heat the tube first, beginning about one inch
from the edge of the fitting, sweeping the flame
around the tube in short strokes at right angles to
the axis of the tube. It is very important that the
flame be in motion and not remain on any one
point long enough to damage the tube. Switch the
flame to the fitting at the base of the fitting socket.
Heat uniformly, sweeping the flame fi*om the fit-
ting to the tube. Avoid excessive heating of cast
fittings or they may crack.
2.4.5 Applying Brazing Filler Metal.
Apply the brazing filler metal at the point where
the tube enters the socket of the fitting. When the
proper temperature is reached, the filler metal will
flow readily into the space between the tube and
fitting socket, drawn in by the natural force of cap-
illary action.
Keep the flame away fi-om the filler metal itself
as it is fed into the joint. The temperature of the
tube and fitting at the joint should be high enough
to melt the filler metal. Keep both the tube and fit-
ting heated by moving the flame back and forth
from one to the other as the filler metal is drawn
into the joint.
When the joint is properly made the filler metal
will be drawn into the fitting socket by capillary
action, and a continuous fillet (cap) of filler metal
will be visible completely around the joint. To aid
in the development of this fillet during brazing,
the flame should be kept slightly ahead of the pint
of filler metal apphcation.
When brazing horizontal joints, it is preferable to
first apply the filler metal slightly off-center of the
bottom of the joint, proceeding across the bottom
of the joint and continuing up the side to the top of
the joint. The return to the beginning point, over-
lapping slightly. This procedure is identical to that
used for soldering. Also, similar to the soldering
process, make sure the operations overlap.
On vertical joints, it is immaterial where the joint
is made. If the opening of the fitting socket is
pointing down, care should be taken to avoid over-
heating the tube, as this may cause the brazing
filler metal to run down the outside of the tube.
If the filler metal fails to flow, or has the tendency
to ball-up, it indicates either that there is oxide on
2010 CALIFORNIA PLUMBING CODE
375
COPPER PLUMBING TUBE, PIPE, AND FITTINGS
the surfaces being joined or that the parts to be
joined are not hot enough. If the filler metal re-
fuses to enter the joint, the fitting cup is not hot
enough. Most poorly made braze joints result
from either the tube or the fitting not being hot
enough. If filler metal tends to flow over the out-
side of either part of the joint, it indicates that part
is overheated in comparison to the other. When
the joint is completed, a continuous fillet should
be visible completely around the joint.
Larger diameter tube is more difficult to heat to
the desired temperature. The use of a heating tip or
rosebud may be necessary to maintain the proper
temperature over the area being brazed. Once total
heat control is attained, follow the same proce-
dures used for smaller tube.
2.4.6 Cooling and Cleaning.
When the brazed joint is finished, allow it to cool
naturally. Flux residues and some oxides formed
by heating can be removed by washing with hot
water and brushing with a stainless steel wire
brush.
2.4.7 Testing.
Test all completed assembles for joint integrity
following the procedures described in the body of
this code. Completed systems should be flushed
to remove excess flux and debris as soon as pos-
sible after completion.
2.4.8 Purging.
Some installations, such as medical gas, high-pu-
rity gas, and ACR systems, require the use of an
inert gas during the brazing process. The purge
gas displaces oxygen from the interior of the sys-
tem while it is being subjected to the high tem-
peratures of brazing and therefore eliminates the
possibility of oxide formation on the interior of
the tube surface.
2.5 Flared Joints.

Step 2 Remove all burrs. This is very important
to assure metal-to-metal contact.
Step 3 Soft temper tube, if deformed, should be
brought back to roundness with a sizing
tool. This tool consists of a plug and siz-
ing ring.
Step 4 Slip the coupling nut over the end of the
tube.
Step 5 Insert flaring tool into the tube end.
Step 6 Drive the flaring tool by hammer strokes,
expanding the end of the tube to the de-
sired flare. This requires a few moder-
ately light strokes.
Step 7 Assemble the joint by placing the fitting
squarely against the flare. Engage the
coupling nut with the fitting threads.
Tighten with two wrenches, one on the
nut and one on the fitting.
2.5.2 Flared Joints with Screw-Type Flaring Tools.
Steps 1-4 Same as for impact flaring previously
described.
Step 5 Clamp the tube in the flaring block so
that the end of the tube is slightly
above the face of the block.
Step 6 Place the yoke of the flaring tool on
the block so that the beveled end of the
compressor cone is over the tube end.
Step 7 Turn the compressor screw down
firmly, forming the flare between the
chamber in the flaring block and the
beveled compressor cone.
Step 8 Remove the flaring tool. The joint can
now be assembled as in Step 6 for im-
pact flaring.
2.6 Sizing, Velocity.
To avoid excess system noise and the possibility
of erosion-corrosion, flow through copper tube
systems should not exceed velocities of 8 feet per
second for cold water and 5 feet per second in hot
water up to approximately 140°F (60°C) [UPC
610.0]
In systems where water temperatures routhiely ex-
ceed HO'^F (60'*C), lower velocities such as 2 to 3
feet per second should not be exceeded. In addi-
tion, where Vi-inch and smaller tube sizes are used,
to guard against localized high velocity turbulence
due to possible faulty workmanship (e.g. burrs at
tube ends which were not properly removed) or
unusually numerous, abrupt changes in flow di-
rection, lower velocities should be considered.
Due to constant circulation and elevated water tem-
peratures, particular attention should be paid to ve-
locities in circulation hot water systems. Both the
supply and return piping should be sized such that
the maximum velocity does not exceed the above
recommendations. Care should be taken to ensure
that the circulating pump is not oversized and the
return piping is not undersized, both common oc-
currences in installed copper piping systems.
3.0 GENERAL INFORMATION.
3.1 It is not possible to cover all the variables of a
plumbing system; however, the following infor-
mation may prove helpful:
Expansion Loops - Copper tube, like all piping
materials, expands and contracts with temperature
changes. Therefore, in a copper tube system sub-
jected to excessive temperature changes, the line
tends to buckle or bend when it expands unless
compensation is built into the system. Severe
stresses on the joints may also occur. Such stresses,
buckles, or bends are prevented by the use of ex-
376
2010 CALIFORNIA PLUMBING CODE
COPPER PLUMBING TUBE, PIPE, AND FITTINGS
pansion joints or by installing offsets, "U" bends,
coil loops, or similar arrangements in the tube as-
sembly. These specially shaped tube segments take
up expansion and contraction without excessive
stress. The expansion of a length of copper tube
may be calculated from the formula:
Temperature Rise (°F) x Length (feet) x
12 (inches per foot) x
Expansion Coefficient (in. per in. per °F) =
Expansion (inches), or
Temperature Rise (°C) x Length (meter) x
1 000 (mm per meter) x
Expansion Coefficient (mm per mm per °C) =
Expansion (mm).
Calculations for expansion and contraction should
be based on the average coefficient of expansion of
copper, which is 0.0000094 per ^F (1.692 x 10-5
per °C), between 70^F (21°C) and212T (100°C).
For example, the expansion of each 100 feet (3048
mm) of length of any size tube heated from room
temperature (70°F) (2rC) to IVO^F (77°C) (a
100°F (38°C) rise) is 1.128 inches (28.7 mm).
lOO^xlOOft. xl2in./ft.x
0.0000094 in./in./^F =1.128 in., or
55.6° X 30.48 m x 1000 mm/m x 1 .692 x
10-5 mm/mm/°C = 28.7 mm
3.2 Tube Supports - See Table 3-2 and Section 3 14.0
in the Uniform Plumbing Code.
3.3 Bending.
3.3.1 Copper tube, properly bent, will not collapse on
the outside of the bend and will not buckle on the
inside of the bend. Tests demonstrate that the
bursting strength of a bent copper tube can be
greater than it was before bending. Because cop-
per is readily formed, expansion loops and other
bends necessary in an assembly are quickly and
simply made if the proper method and equipment
are used. Simple hand tools employing mandrels,
dies, forms, and fillers, or power-operated bending
machines are used.
Both annealed tube and bending-temper tube can
be bent with hand benders. The proper size bender
for each size tube must be used. Usually the size
of the tool corresponds to the nominal outside di-
ameter of the tube, not the standard tube size. For
a guide to the typical bend radii, see the following
bending guide for copper tube.

2.2.2 Expansion And Contraction.
Thermal expansion and contraction of plastic drain
waste and vent systems shall be taken into consid-
eration. Thermal expansion and contraction may be
controlled by several methods: offset, expansion
joints, or restraints. Regardless of method utilized,
certain conditions shall be met.
(a) Support, but do not rigidly restrain piping at
changes of direction.
(b) Do not anchor pipe rigidly in walls.
(c) Holes through framing members must be ad-
equately sized to allow for free movement.
DWV installations with frequent changes in di-
rection will compensate for thermal expansion
and contraction. Expansion joints may be utilized
in vertical straight runs in excess of thirty (30) feet
(9,144 mm) provided they are installed per man-
ufacturer's installation instructions.
Except piping buried below ground, horizontal and
vertical piping should be installed with restraint
fittings or a minimum twenty-four (24) inches (610
mm) 45° offset every thirty (30) feet (9144 mm).
Thermal expansion for installations subject to
temperature changes may be determined from
Table 1 . The linear expansion shown is independ-
ent of the diameter of the pipe. [UPC 313.0]
2.2.3 Exposed Piping.
Piping shall not be exposed to direct sunHght. Ex-
ception: Vent piping through roof Plumbing vents
through roof, exposed to sunlight, shall be pro-
tected by water base synthetic latex paints. Ade-
quate support shall be provided where ABS
piping is exposed to wind, snow, and ice loading.
2.2.4 Protection From Damage.
Piping passing through wood studs or plates shall
be protected from puncture by steel nail plates not
less than 18 gauge. Piping shall be protected from
concrete form oil. [UPC 313.9]
2.2.5 Anti-Freeze Protection.

be protected from freezing by the use of one of
the following solutions or mixtures:
(a) 4 quarts (3.8 liters) of water mixed with 5
quarts (4,8 liters) of glycerol
(b) 2^2 lbs. (1.1 kg) of magnesium chloride dis-
solved in one gallon (3.8 liters) of water
(c) 3 lbs. (1.4 kg) of table salt dissolved in one
gallon (3.8 liters) of water.
The salt solutions are effective to approximately
10°F (-12°C). If lower temperatures are antici-
pated, the pipe should be drained or the glycerol
solution should be used. [UPC 313.6]
2.2.6 Piping Installed in Fire Resistive Construction.
All piping penetrations of frre resistance rated
walls, partitions, floors, floor/ceiling assemblies,
roof/ceihng assembUes, or shaft enclosures shall
be protected in accordance with the requirements
of the California Building Code and \A?MO In-
stallation Standards. [UPC 313.7]
2.3 Hangers and Supports.

cut, or abrade the piping and shall allow free
movement of pipe. Pipe exposed to damage by
sharp surfaces shall be protected. [UPC 314.0]
2.3.2 Support.
Support all piping at intervals of not more than
four (4) feet (1,219 mm), at end of branches, and
at change of direction or elevation. Supports shall
allow free movement, but shall restrict upward
movement of lateral runs so as not to create reverse
grade. Vertical piping shall be supported at each
story or floor level. Ahgnment of vertical piping
shall be maintained between floors with the use of
a mid- story guide. Support trap arms in excess of
three (3) feet (914 mm) in length as close as pos-
sible to the trap. Closet rings shall be securely fas-
tened with corrosive resistant fasteners to the floor
with the top surface one-quarter {}A) inch (6.4 mm)
above the finish floor. [UPC 3 14.0]
2.4 Traps.
2.4.1 Connection to Traps.
Traps shall be connected by means of Usted trap
adapters. [UPC 1003.0]
2.5 Joints.
2.5.1 Caulked Joints.
Make connections or transitions to bell-and- spigot
cast iron soil pipe and fittings, and to bell-and-
spigot pipe and fittings of other materials with
listed mechanical compression joints designed for
this use, or caulked joints made in an approved
manner. In caulking, pack the joint with oakum or
hemp and fill with molten lead to a depth of not
less than (1) inch (25.4 mm). Allow a period of

2.5.2.2 Handling (to maintain effectiveness). Solvent ce- 2.5.3.2
ment containers no larger than 1 gallon (3.8 liters)
should be used in the field (to avoid thickening due
to evaporation). Keep container closed and in the
shade when not in use. Keep applicator submerged
in solvent cement between applications. When sol-
vent cement becomes thicker, THROW IT AWAY. 2.5.3.3
Solvent cement shall NOT be thinned.
2.5.2.3 Size of Applicator. Applicator should be about 2.5.3.4
one half the pipe diameter. Do not use small ap-
plicator on large pipes. Ordinary pure bristle paint 2 5 3 5
brush or applicators furnished with product are
satisfactory.
2.5.2.4 Application. Solvent cement shall be applied de- 2.5.3.6
liberately, but without delay (two people may be
needed to make large joints). Use special care when
temperature is over 100°F (38°C) or humidity is
over 60%.
2.5.3 SAFETY REQUIREMENTS AND PRE-
CAUTIONS.
2.5.3.1 General. Solvents contained in ABS plastic pipe
cements are classified as airborne contaminants
and flammable and combustible liquids. Precau- 2.5.3.7
tions listed in this appendix should be followed to
avoid injury to personnel and the hazard of fire.
Safety Precautions. Prolonged breathing of sol-
vent vapors should be avoided. When pipe and fit-
tings are being joined in partially enclosed areas, a
ventilating device should be used in such a manner
to minimize the entry of vapors into the breathing
areas.
Solvent cements should be kept away from all
sources of ignition, heat, sparks and open flame.
Containers for solvent cements should be kept
tightly closed except when the cement is being used.
All rags and other materials used for mopping up
spills should be kept in a safety waste receptacle
which should be emptied daily.
Most of the solvents used in ABS pipe cements can
be considered eye irritants and contact with the eye
should be avoided for it may cause eye injury.
Proper eye protection and the use of chemical gog-
gles or face shields is advisable where the possi-
bility of splashing exists in handling solvent
cements. In case of eye contact, flush with plenty
of water for 15 minutes and call a physician im-
mediately.
Repeated contact with the skin should be avoided.
Proper gloves impervious to and unaffected by the
solvents should be worn when fi*equent contact
2010 CALIFORNIA PLUMBING CODE
385
ABS BUILDING DRAIN, WASTE, AND VENT PIPE AND FITTINGS
with the skin is likely. Application of the solvents
or solvent cements with rags and bare hand is not
recommended. Brushes and other suitable appli-
cators can be used effectively for applying the sol-
vent cement, thus avoiding skin contact. In the
event of excessive contact, remove contaminated
clothing and wash skin with soap and water.
Step 1 Cut pipe square with hand saw and miter
box, mechanical cut-off saw, or tube cut-
ter designed for plastic.
Step 2 Ream inside and chamfer outside of pipe
(to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease from
pipe and socket. Use a clean, dry rag.
Step 4 Check dry fit of pipe in fitting. Pipe
should enter fitting socket from I/3 to %
depth of socket.
Step 5 Apply a light coat of ABS solvent ce-
ment to inside of socket using straight
outward strokes (to keep excess solvent
out of socket). This is also to prevent sol-
vent cement damage to pipe. For loose
fits, apply a second coat of solvent ce-
ment. Time is important at this stage. See
Section 2.5.2.4.
Step 6
Step?
Steps
While both the inside socket surface and
the outside surface of the pipe are SOFT
and WET with solvent cement, forcefully
bottom the pipe in the socket, giving the
pipe a one-quarter turn, if possible. The
pipe must go to the bottom of the socket.
Hold the joint together until tight (partial
set).
Wipe excess cement from the pipe. A
properly made joint will normally show
a bead around its entire perimeter. Any
gaps may indicate insufficient cement or
the use of light bodied cement on larger
diameters where heavy bodied cement
should have been used.
Step 9
The system shall not be tested until the
joints have cured (set) at least as long as
recommended by the manufacturer.
2.5.4 Threaded JoiRts.
Threads on iron pipe size (IPS) pipe and fittings
shall be standards listed in Table 14-1. Threads on
tubing shall be approved types. Threads on plas-
tic pipe shall be factory cut or molded. Threaded
plastic pipe shall be Schedule 80 minimum wall
thickness. Tubing threads shall conform to fine
tubing thread standards. When a pipe joint mate-
rial is used, it shall be applied only on male
threads and such materials shall be approved
types, insoluble in water and nontoxic. Cleanout
plugs and caps shall be lubricated with water-in-
soluble, non-hardening material or tape. Only
listed thread tape or thread lubricants and sealants
specifically intended for use with plastics shall be
used on plastic threads. Conventional pipe thread
compounds, putty, hnseed oil base products, and
unknown lubricants and sealants shall not be used
on plastic threads. [UPC 316.1.1]
2.5.5 Special Joints.
2.5.5.1 Plastic Pipe to Other Materials.
When connecting plastic pipe to other types of
piping, use only listed fittings and adapters, de-
signed for the specific transition intended. [UPC
316.2.3]
2.6 Prohibited Joints and Connections.
(a) Drainage system - Any fitting or connection
which has an enlargement, chamber, or recess
with a ledge, shoulder, or reduction of pipe
area, that offers an obstruction to flow
through the drain is prohibited.
(b) No fitting or connection that offers abnormal
obstruction to flow shall be used. The en-
largement of a three (3) inch (76 mm) closet
bend or stub to four (4) inches (102 mm) shall
not be considered an obstruction. [UPC

Storage. Unprotected pipe should not be stored in
direct sunlight. The pipe shall be stored in a way to
protect it from mechanical damage (slitting, punc- 2.6.1.2
turing, etc.). Exposure to sunlight during normal
construction periods is not harmful. PVC solvent
cements should be stored in a cool place, except
when actually in use at the job site. The solvent ce-
ment manufacturer's specific storage recommen-
dations should be followed. [UPC 313.0]
Alignment. Pipe and fittings shall be aligned
properly without strain.
Thermal Expansion. Pipe (except pipe with elas-
tomeric gasketed joints) shall be "snaked" in the
trench bottom with enough slack, at least 6 inches
(152.4 mm) per 100 feet (30,480 mm), to com-
pensate for thermal expansion and contraction be-
fore stabilizing piping. Stabilize piping by
bringing it approximately to operating tempera-
ture before testing and backfilling by one of the
following methods:
(a) Shade backfill. Leave all joints exposed so
that they can be examined during pressure
test.
(b) Fill with water at operating temperature.
(c) Allow to stand overnight.
Exposed Piping. Vertical piping may extend a
maximum of 24 in. (610 mm) above grade when
located on the exterior of the building or structure
and protected from mechanical damage to the sat-
isfaction of the Administrative Authority. Where
exposed to sunlight, the pipe shall be wrapped
with at least 0.040 in. (1.0 mm) of tape or other-
wise protected from UV degradation.
Trenching, Cover and Backfill.
Trenching and Cover. Trench bottoms shall be
uniformly graded and shall be of either undis-
turbed soil or shall consist of a layer or layers of
compacted backfill so that minimum settlement
will take place. [UPC 315.0]
Backfill. Selected backfill shall be used. Tamp the
backfill that is placed around the pipe so as to pro-
vide firm continuous support and proper com-
paction. Backfill at least 12 inches (305 mm) over
pipes, except that joints shall be left exposed.
After inspection and pressure test, complete back-
fill [UPC 315.4]
Elastomeric Joints. Backfill immediately after
installing pipe.
Note: This is to maintain equal spaces within the
joints for contraction and expansion.

Handling (to maintain effectiveness). Package
solvent cement in containers no larger than 1 quart
(1 liter). Keep solvent cement can closed and in
the shade when not in use. Keep applicator sub-
merged in solvent cement between applications.
When solvent cement becomes thicker, THROW
IT AWAY. Solvent cement shall NOT be thinned.
Size of Applicator. Applicator should be about
one half the pipe diameter. Do not use small ap-
plicator on large pipes.
Primers. All solvent cement PVC joints shall be
made using a listed primer in compliance with
ASTM F 656 and as specified in Section 316.1.6
of the UPC.
Application. Solvent cement shall be applied de-
liberately, but without delay (two men may be
needed to make large joints). Use special care
when temperature is over 100°F (38°C) or hu-
midity is over 60%.
Procedure.
Note: Do not take SHORT CUTS. Most failures
are caused by short cuts. DON'T TAKE A
CHANCE.
SAFETY REQUIREMENTS AND PRECAU-
TIONS >
General. Solvents contained in PVC plastic pipe
cements are classified as airborne contaminants
and flammable and combustible liquids. Precau-
tions listed in this appendix should be followed to
avoid injury to personnel and the hazard of fire.
Safety Precautions. Prolonged breathing of sol-
vent vapors should be avoided. When pipe and fit-
tings are being joined in partially enclosed areas, a
ventilating device should be used in such a manner
to minimize the entry of vapors into the breathing
areas.
Solvent cements should be kept away from all
sources of ignition, heat, sparks, and open flame.
Containers for solvent cements should be kept
tightly closed except when the cement is being used.
All rags and other materials used for mopping up
spills should be kept in a safety waste receptacle
which should be emptied daily.
Most of the solvents used in PVC pipe cements can
be considered eye irritants and contact with the eye
should be avoided for it may cause eye injury.
Proper eye protection and the use of chemical gog-
gles or face shields is advisable where the possibil-
ity of splashing exists in handling solvent cements.
In case of eye contact, flush with plenty of water
for 15 minutes and call a physician immediately.
Repeated contact with the skin should be avoided.
394
2010 CALIFORNIA PLUMBING CODE
PVC COLD WATER BUILDING SUPPLY AND YARD PIPING
Proper gloves impervious to and unaffected by the
solvents should be worn when frequent contact
with the skin is likely. Application of the solvents
or solvent cements with rags and bare hands is not g^^p 1 3
recommended. Brushes and other suitable appli-
cators can be used effectively for applying the sol-
vent cement, thus avoiding skin contact. In the
event of excessive contact, remove contaminated
clothing and wash skin with soap and water. ^ ^ ^
CAUTION: Primers are toxic. Don't allow them to touch
skin. Suitable gloves are advised.
Step 1 . Cut pipe square with hand saw and miter box, me-
chanical cut-off saw or tube cutter designed for
plastic.
Step 2. Ream and chamfer pipe (to eliminate sharp edges,
beads, and all burrs). 2,6.4
Step 3. Clean all dirt, moisture and grease from pipe and step 1 .
fitting socket. Use a clean, dry rag.
Step 4. Check dry fit of pipe in fitting. Pipe should enter
fitting socket from V3 to Va depth of socket. Step 2.
Step 5. Soften inside socket surface by applying an ag-
gressive primer. Step 3.
Step 6. Soften mating outside surface of pipe to depth of
socket by applying a liberal coat of the (aggres- Step 4.
sive) primer. Be sure entire surface is softened.
Step 7. Again coat inside socket surface with the (ag-
gressive) primer. Then, without delay, apply sol-
vent cement liberally to outside of pipe. Use more Step 5.
than enough to fill any gaps.
Step 8. Apply a light coat of PVC solvent cement to in-
side of socket using straight outward strokes (to
keep excess solvent out of socket). This is also to Step 6.
prevent solvent cement damage to pipe. For loose
I fits, apply a second coat of solvent cement. Time
is important at this stage. See Section 2.6.1.5.
Step 9. While both the inside socket surface and the out-
side surface of the pipe are SOFT and WET with
solvent cement, forcefully bottom the pipe in the
socket, giving the pipe a one-quarter turn, if pos-
sible. The pipe must go to the bottom of the socket.
Step 1 0. Hold the joint together until tight. 2.7
Step 11. Wipe excess cement from the pipe. A properly 2.7.1
made joint will normally show a bead around its
entire perimeter. Any gaps may indicate insuffi-
cient cement or the use of light bodied cement on
larger diameters where heavy bodied cement
should have been used.
Step 12. Do not disturb joint for the following periods:
30 minutes minimum at 60°F to lOO^F (16°C to
38°C).
1 hour minimum at 40°F to 60°F (4°C to 16''C).
2 hours minimum at 20°F to 40°F (-TC to 4^C).
4 hours minimum at O^'F to 20°F (-18°C to -TC).
Handle the newly assembled joints carefully dur-
ing these periods. If gaps (step 1 1) or loose fits are
encountered in the system, double these periods.
The system shall not be pressurized until the joints
have cured (set) at least as long as recommended
by the manufacturer. If manufacturer's recom-
mendation is not available, the following cure
times are required.
Threaded Joints. Joints shall be tightened ap-
proximately Vi turn past hand tight, using a strap
wrench.
Caution: Handtight refers to number of threads
to reach handtight with metal pipe. Pipe can be
bottomed in small sizes of PVC by hand pressure
alone. Do not overtighten.
Elastomeric Gasketed Joints, Procedure:
For field cuts, cut end of pipe square with hand-
saw and miter box, mechanical saw or a tube cut-
ter designed for plastic.
Ream and bevel end of pipe (unless already done
by manufacturer).
If dirty, remove gasket, clean gasket and groove
and replace ring.
Mark pipe in a contrasting color to indicate the
proper insertion depth as recommended by the
manufacturer (unless already done by manufac-
turer).
Apply lubricant recommended by pipe manufac-
turer to end of pipe. Do not apply lubricant to gas-
ket or the groove unless otherwise specifically
recommended by the manufacturer.
Insert pipe into fitting until mark on pipe is even
with fitting.
Note: This depth of insertion is required to prop-
erly allow for thermal expansion and contraction.
During joint assembly, the previously installed
length of pipe should be held so that the existing
joints are not pushed together or pulled apart. DO
NOT USE METAL STRAPS, CHAINS (OR THE
LIKE) FOR ASSEMBLY.
Material.
Location. PVC piping shall be installed only out-
side the foundation of any building or structure or
parts thereof. It shall be buried in the ground for
its entire length except vertical piping may be ex-
tended above grade per Section 2.4.4. It shall not
be installed within or under any building or struc-
ture or mobile home or commercial coach or parts
thereof The term "building or structure or parts
thereof shall include structures such as porches
and steps, whether roofed or not, roofed porte-
cocheres, roofed patios, carports, covered walks,
covered driveways and similar structures or ap-
purtenances. [UPC 604.0]

Example for Table 2:
For a pressure of 150 psi (1,033.5 kPa) on a 4 inch
(102 mm) tee, Table 2 indicates 1,620 pounds
(7,209 N) for 100 psi (689 kPa). Therefore, total
thrust for 150 psi (1033.5 kPa) will equal V/i
times 1620 pounds (7,209 N) for a total thrust of
2430 pounds (10,810 N).
To determine the bearing area of thrust blocks,
refer to Table 4 for the safe bearing load of the soil
and divide the total thrust by this safe bearing load.

blocks, either permanent or temporary, shall be in-
stalled at all required points before testing. See
Section 2.8.4. When concrete thrust blocks are in-
stalled, wait at least 24 hours before pressure test-
ing.
2.9.2 Solvent Cement Joints. The entire system shall
be purged before testing to eliminate all solvent
cement vapors and air.
CAUTION: Water test only.
2.9.3 Identification. A label shall be fastened to the
main electrical meter panel stating, "This struc-
ture has a nonmetallic water service".
2.10 Sizing.
2.10.1 Piping shall be sized in accordance with UPC Sec-
tion 610.0. When UPC Appendix A is applicable,
use UPC Chart A-5 (Fairly smooth). Flow veloc-
ity shall not exceed 8 fps (2.4 m/s). [UPC 610.0]

2.5.2
2.3.2 Expansion and Contraction.
Thermal expansion and contraction of plastic drain
waste and vent systems shall be taken into consid- 2.4
eration. Thermal expansion and contraction may
be controlled by several methods: offset, expan-
sion joints, or restraints.
Regardless of method utilized, certain conditions
shall be met:
(a) Support, but do not rigidly restrain piping at
changes of direction.
(b) Do not anchor pipe rigidly in walls.
(c) Holes through framing members must be ad- 2.5.0
equately sized to allow for free movement. 2 51
DWV installation with frequent changes in direc-
tion will compensate for thermal expansion and
contraction.
Expansion joints may be utilized in vertical
straight runs in excess of 30 feet (9,144 mm) pro-
vided they are installed per manufacturer's instal-
lation instructions.
Except piping buried below ground, horizontal
and vertical piping should be installed with re-
straint fittings or a minimum of 24 inches (610
mm) 45° offset every 30 feet (9,144 mm). Ther-
mal expansion for installation subject to tempera-
ture changes may be determined from Table 3-1.
The linear expansion shown is independent of the
diameter of the pipe. [UPC 313.0]
2.3.3 Exposed Piping.
Piping shall not be exposed to direct sunlight.
Exception: Vent piping through roof. Plumbing
vents through roof, exposed to sunlight, shall be
protected by water base synthetic latex paints.
Adequate support shall be provided where PVC
piping is exposed to wind, snow, and ice loading.
2.3.4 Protection from Damage.
Piping passing through wood studs or plates shall
be protected from puncture by minimum Vie inch
(1 .6 mm) thick steel plate.
Piping shall be protected from concrete form oil.
[UPC 313.9]
2.3.5 Anti-Freeze Protection.
PVC pipe and traps can be protected from freez-
ing by the use of one of the following solutions of
mixtures:
(a) 4 quarts (3.8 liters) of water mixed with 5
quarts (4.8 liters) of glycerol.
(b) 2^2 lbs. (1.1 kg) of magnesium chloride dis-
solved in one (1) gallon (3.8 liters) of water.
(c) 3 lbs. (1.4 kg) of table salt dissolved in one
(1) gallon (3.8 liters) of water. 2.7.2
The salt solutions are effective to approximately
lO^F (-12°C). If lower temperatures are antici-

pated, the pipe should be drained or the glycerol
solution should be used. [UPC 313.6]
Piping Installed in Fire Resistive Construction.
Where piping is installed and penetrates required
fire resistive construction, the fire resistive in-
tegrity of the construction shall be as required by
the Administrative Authority, or when not estab-
lished by the Building Code, by qualified testing
methods approved by the Administrative Author-
ity. Approval shall be obtained prior to installing
any such piping. [UPC 313.7]
Hangers and Supports.
Abrasion.
Hangers and straps shall not compress, distort,
cut, or abrade the piping and shall allow free
movement of pipe. Pipe, exposed to damage by
sharp surfaces, shall be protected. [UPC 314.0]
Support.
Support all horizontal piping at intervals of not
more than four (4) feet (1,219 mm), at end of
branches, and at change of direction or elevation.
Supports shall allow free movement, but shall re-
strict upward movement of lateral runs so as not to
create reverse grade. Vertical piping shall be sup-
ported at each story or floor level. Ahgnment of
vertical piping shall be maintained between floors
with the use of a mid-story guide. Support trap
arms in excess of three (3) feet (915 mm) in length
as close as possible to the trap. Closet flanges shall
be securely fastened with corrosive resistant fas-
teners to the floor with top surface one-quarter (Va)
inch (6.4 mm) above finish floor. [UPC 314.0]
Traps.
Connection to Traps.
Traps shall be connected by means of listed trap
adapters. [UPC 1003.0]
Joints.
Caulked Joints.
Make connections or transitions to bell-and-spigot
cast iron soil pipe fittings, and to bell-and-spigot
pipe and fittings of other materials with listed me-
chanical compression joints designed for this use,
or caulked joints made in an approved manner. In
caulking, pack the joint with oakum or hemp and
fill with molten lead to a depth of not less than one
(1) inch (25.4 mm). Allow a period of four (4)

2.7.3 Selection. Follow manufacturer's recommenda-
tions for type of solvent cement for such condi-
tions as temperature over lOO^F (38°C), or
humidity over 60%.
2.7.4 Handling (to maintain effectiveness). Solvent
cement and primer containers no larger than 1
quart (1 liter) should be used in the field (to avoid
thickening due to evaporation). Keep containers
closed and in the shade when not in use. Keep ap-
plicator submerged in solvent cement between ap-
plications. When solvent cement becomes thicker,
THROW IT AWAY. Solvent cement shall NOT be
thinned.
2.7.5 Size of Applicator. Applicator should be about
one-half the pipe diameter. Do not use small ap-
plicator on large pipes. Ordinary pure bristle paint
brushes or applicators furnished with product are
satisfactory. [UPC 316.1.6]
2.7.6 Primers, A listed primer in compliance with
ASTM F 656 shall be used on all PVC DWV
joints.
2.7.7 Application. Solvent cement and primer shall be
applied deliberately, but without delay (two men
may be needed to make large joints). Use special
care when temperature is over lOO^F (38°C) or
humidity is over 60%.
2.7.8 SAFETY REQUIREMENTS AND PRECAU-
TIONS.
2.7.8.1 General. Solvents contained in PVC plastic pipe
cements are classified as airborne contaminants
and flammable and combustible liquids. Precau-
tions listed in this appendix should be followed to
avoid injury to persoimel and the hazard of fire.
2.7.8.2 Safety Precautions. Prolonged breathing of sol-
vent vapors should be avoided. When pipe and fit-
tings are being joined in partially enclosed areas, a
ventilating device should be used in such a manner
to minimize the entry of vapors into the breathing
areas.
2.7.8.3 Solvent cements should be kept away from all
sources of ignition, heat, sparks and open flame.
2.7.8.4 Containers for solvent cements should be kept
tightly closed except when the cement is being used.
2.7.8.5 All rags and other materials used for mopping up
spills should be kept in a safety waste receptacle
which should be emptied daily.
2.7.8.6 Most of the solvents used in PVC pipe cements
can be considered eye irritants and contact with
the eye should be avoided for it may cause eye in-
jury. Proper eye protection and the use of chemi-
cal goggles or face shields is advisable where the
2010 CALIFORNIA PLUMBING CODE
403
PVC BUILDING DRAIN, WASTE, AND VENT PIPE AND FITTINGS
possibility of splashing exists in handling solvent
cements. In case of eye contact, flush with plenty
of water for 1 5 minutes and call a physician im-
mediately.
2.7.8.7 Repeated contact with the skin should be avoided.
Proper gloves impervious to and unaffected by the
solvents should be worn when frequent contact
with the skin is likely. Application of the solvents
or solvent cements with rags and bare hand is not
recommended. Brushes and other suitable appH-
cators can be used effectively for applying the sol-
vent cement, thus avoiding skin contact. In the
event of excessive contact, remove contaminated
clothing and wash skin with soap and water.
Step 1 Cut pipe square with hand saw and miter
box, mechanical cut-off saw or tube cut-
ter designed for plastic.
Step 2 Ream inside and chamfer outside of pipe
(to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease from
pipe and socket. Use a clean, dry rag.
Step 4 Check dry fit of pipe in fitting. Pipe
should enter fitting socket from V2 to Va
depth of socket.
Step 5 Soften inside socket surface by applying
an aggressive primer.
Step 6 Soften mating outside surface of pipe to
depth of socket by applying a liberal coat
of the (aggressive) primer. Be sure the
entire surface is softened.
Step 7 Again coat inside socket surface with the
(aggressive) primer. Then, without delay,
apply solvent cement liberally to outside
of pipe. Use more than enough to fill any
gaps.
Step 8 Apply a light coat of PVC solvent ce-
ment to inside of socket using straight
outward strokes (to keep excess solvent
out of socket). This is also to prevent sol-
vent cement damage to pipe. For loose
fits, apply a second coat of solvent ce-
ment. Time is important at this stage.
See Section 2.7.6.
Step 9 While both the inside socket surface and
the outside surface of the pipe are SOFT
and WET with solvent cement, force-
fully bottom the pipe in the socket, giv-
ing the pipe a one-quarter turn, if
possible. The pipe must go to the bottom
of the socket.
Step 10 Hold the joint together until tight. (Par-
tial set).
Step 11 Wipe excess cement from the pipe. A
properly made joint will normally show
a bead around its entire perimeter. Any
gaps may indicate insufficient cement or
the use of light bodied cement on larger
2.7.9
2.7.10
2.7.10.1
2.7.11
diameters where heavy bodied cement
should have been used.
Step 12 The system shall not be tested until the
joints have cured (set) at least as long as
recommended by the manufacturer.
Threaded Joints.
Listed adapter fittings shall be used for the transi-
tion to threaded connections. No threaded PVC
female fitting(s) or joint(s) shall be located in a
non-accessible location. The joint between the
PVC pipe and adapter fittings shall be of the sol-
vent cement type.
Only listed thread tape or thread lubricant, specif-
ically intended for use with plastics, shall be used.
Conventional pipe thread compounds, putty, lin-
seed oil base products, and unknown mixtures
shall not be used. Pipe and fittings which have
come in contact with the above non-approved
mixtures shall be removed and replaced with new
materials.
Where a threaded joint is made, obtain tightness
by maximum hand tightening plus additional
tightening with a strapwrench not to exceed one
full turn.
Special Joints.
Connection to Non-Plastic Pipe.
When connecting plastic pipe to other types of
piping, use listed fittings and adapters designed
for the specific use intended. [UPC 316.2]
Prohibited Joints and Connections.
(a) Drainage System - Any fitting or connection
which has an enlargement, chamber or recess
with a ledge, shoulder, or reduction of pipe
area, that offers an obstruction to flow
through the drain is prohibited.
(b) No fitting or connection that offers abnormal
obstruction to flow shall be used. The en-
largement of a three (3) inch (76 mm) closet
bend or stub to four (4) inches (102 mm)
shall not be considered an obstruction. [UPC

merged in solvent cement between applications.
When solvent cement becomes thicker, THROW
IT AWAY. Solvent cement shall NOT be thinned.
2.7.3.3 Size of Applicator. Applicator should be about
one half the pipe diameter. Do not use small ap-
plicator on large pipes. Ordinary pure bristle paint
brush or applicators furnished with product are
satisfactory.
2.7.3.4 Application. Solvent cement shall be applied de-
liberately, but without delay (two men may be
needed to make large joints). Use special care
when temperature is over 100°F (38°C) or hu-
midity is over 60%.
2.7.4 SAFETY REQUIREMENTS AND PRECAU-
TIONS.
2.7.4.1 General. Solvents contained in ABS plastic pipe
cements are classified as airborne contaminants
and flammable and combustible liquids. Precau-
tions listed in this appendix should be followed to
avoid injury to personnel and the hazard of fire.
2.7.4.2 Safety Precautions. Prolonged breathing of sol-
vent vapors should be avoided. When pipe and fit-
tings are being joined in partially enclosed areas,
a ventilating device should be used in such a man-
ner to minimize the entry of vapors into the
breathing areas.
2.7.4.3 Solvent cements should be kept away from all
sources of ignition, heat, sparks, and open flame.
2.7.4.4 Containers for solvent cements should be kept
tightly closed except when the cement is being used.
2.7.4.5 All rags and other materials used for mopping up
spills should be kept in a safety waste receptacle
which should be emptied daily.
2.7.4.6 Most of the solvents used in ABS pipe cements can
be considered eye irritants and contact with the eye
should be avoided for it may cause eye injury.
Proper eye protection and the use of chemical gog-
gles or face shields is advisable where the possibil-
ity of splashing exists in handling solvent cements.
In case of eye contact, flush with plenty of water
for 1 5 minutes and call a physician immediately.
2.7.4.7 Repeated contact with the skin should be avoided.
Proper gloves impervious to and unaffected by the
solvents should be worn when frequent contact
with the skin is likely. Application of the solvents or
solvent cements with rags and bare hand is not rec-
ommended. Brushes and other suitable applicators
can be used effectively for applying the solvent ce-
ment, thus avoiding skin contact, hi the event of ex-
cessive contact, remove contaminated clothing and
wash skin with soap and water.
Step 1 Cut pipe square with hand saw and
miter box, mechanical cut-off" saw, or
tube cutter designed for plastic.
Step 2 Ream inside and chamfer outside of
pipe (to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease
from pipe and socket. Use a clean, dry
rag.
Step 4 Check dry fit of pipe in fitting. Pipe
should enter fitting socket from Vi> to

outward strokes (to keep excess sol-
vent out of socket). This is also to pre-
vent solvent cement damage to pipe.
For loose fits, apply a second coat of
solvent cement. Time is important at
this stage. See Section 2.7.3.4.
Step 6 While both the inside socket surface
and the outside surface of the pipe are
SOFT and WET with solvent cement,
forcefully bottom the pipe in the
socket, giving the pipe a one-quarter
turn, if possible. The pipe must go to
the bottom of the socket.
Step 7 Hold the j oint together until tight (par-
tial set).
Step 8 Wipe excess cement from the pipe. A
properly made joint will normally
show a bead around its entire perime-
ter. Any gaps may indicate insufficient
cement or the use of light bodied ce-
ment on larger diameters where heavy
bodied cement should have been used.
Step 9 The system shall not be tested until
the joints have cured (set) at least as
long as recommended by the manu-
facturer.
2.7.5 Special Joints.

at:
(a) Changes in direction, as at tees and bends;
(b) Changes in size, as at reducers;
(c) Stops, as at dead ends; and
(d) Valves, where thrusts may be expected.
The size and type of thrust block shall be based on
the pressure rating of the pipe (or line test pressure,
if greater than piping rating), pipe size and kind of
soil 2.5.4(b). Refer to Table 1 for thrust at fittings for
a pressure of one hundred (100) pounds per square
inch (689 kPa).
To determine the bearing area of thrust blocks,
refer to Table 2 for the safe bearing load of the
soil and divide the total thrust by this safe bearing
load.
Thrust blocks shall be located as shown on Chart 1 .
Testing.
The portion of the line being tested should be
complete with thrust blocks or properly sized tem-
porary thrust blocking. The line may be pressure
tested immediately after installation, provided
however, that if poured concrete thrust blocks
have been utilized, they have had a 24-hour pe-
riod to attain an initial cure. [UPC 609.4]
The entire system shall be filled with water,
purged of air, and tested at a pressure at least equal
to the eventual operating pressure for at least one
(1) hour before inspection and backfilling of
trench. It is recommended that the test pressure not
exceed the working pressure of the pipe.
CAUTION: AIR TESTING IS PROHIBITED.
Identification. A label shall be fastened to the
main electrical meter panel stating, "This struc-
ture has a non-metallic water service."

Example: For a pressure of 150 psi (1,033.5 kPa) on a 4 inch
(102 mm) tee, Table 1 indicates 1850 pounds (8,232.5 N) for
100 psi (689 kPa). Therefore, total thrust for 150 psi (1,033.5
kPa) will equal VA times 1,850 pounds (82,32.5 N).
Example: Assume a 4,000 pound (17,800 N) total thrust was
computed. The soil condition is sand. The required bearing area
of the thrust block is 4,000 lbs. (17,800 N) divided by 2,000
lbs. (13,780 kPa) or 2 sq. ft. (0.19 m^)

fornia Plumbing Code and this Appendix for the
installation of CPVC Solvent Cemented Hot and
Cold Water Distributions Systems, all installations
of CPVC pipe within residential structures shall
meet the following:
1.2 A Flushing Procedures. All installations of CPVC
pipe within residential structures shall be flushed
twice over a period of at least one (I) week. The
pipe system shall be first flushed for at least 10
minutes and then filled and allowed to stand for
no less than I week, after which all the branches of
the pipe system must be flushed long enough to
fully empty the contained volume. At the time of
fill, each fixture shall have a removable tag applied
stating:
"This new plumbing system was first filled on
(date) by (name). The California Department of
Housing and Community Development requires
that the system be flushed after standing at least
one week after the fill date specified above. If the
system is used earlier than one week after the fill
date, the water must be allowed to run for at least
two minutes prior to use for human consumption.
This tag may not be removed prior to flushing, ex-
cept by the homeowner "
1, 2, 2 Worker Safety Measures. Mechanical ventilation
sufficient to maintain exposures below the rele-
vant exposure limits established by state regula-
tion shall be provided in enclosed spaces. This
ventilation shall be directed at the breathing zone
of the worker installing the pipe. Where mechan-
ical ventilation is not practical, respirators, suit-
able for organic vapors, shall be used. For the
purpose of this subdivision, an enclosed space is
defined as:

Section 313.9 of the Uniform Plumbing Code.
Storage and Handling. Pipe shall be stored in a
way to protect it from mechanical damage (slit-
ting, puncturing, etc.). It shall be stored under
cover to keep it clean and avoid long term expo-
sure to sunlight. Exposure to sunlight during nor-
mal construction periods is not harmful. CPVC
solvent cements should be stored in a cool place
except when actually in use on the job site. The
solvent cement manufacturer's specific storage
instruction should be followed.
Freezing. In areas where the system must be
drained to protect it from freezing, horizontal
lines shall be graded to drain.
Overheating:
(a) Tubing shall not be positioned or closer to
devices that generate heat such that the
temperature around the CPVC tubing is
greater than 180°F.
(b) Do not apply direct flame onto CPVC.
Thermal Expansion.
General. Allowance for thermal expansion and
contraction shall be provided by approved means.
Allowance shall be based on an expansion rate of
3.5 inches (89 mm) per 100 feet (30,480 mm) of
length of run per 100°F (38°C) temperature
change.
Note: Expansion rate is independent of the size
of the pipe.
Offsets and Loops. Thermal expansion may be
provided for by use of expansion loops, offsets,
or changes of direction. From Table 1 determine
the length "L" that is required. Note that "L" is
based on length of run, diameter of pipe, and
maximum temperature of water.
Clearance. Adequate clearance shall be pro-
vided between piping and structure (such as
bored holes and sleeves) to allow for free lon-
gitudinal movement.
2.6 Hangers and Supports.
2.6.1 Vertical Piping. Vertical piping shall be sup-
ported at each floor or as specified by the design
engineer to allow for expansion/contraction.
Piping shall have a mid-story guide. [UPC
314.0]
2.6.2 Horizontal Piping, Unless an engineered de-
sign is provided and approved by the Adminis-
trative Authority, the following provisions shall
apply. Horizontal piping 1 inch (25.4 mm) or
smaller shall be supported at maximum 3 foot
(914 mm) intervals. Piping I V^ inch (32 mm) or
larger shall be supported at maximum 4 foot
(1219 mm) intervals.
2.6.3 Hangers and Anchors. Piping shall not be an-
chored rigidly to a support, but rather secured
with smooth hangers or straps that provide for
a degree of movement and that prevent damage
to the pipe. Hangers or straps with sharp or
abrasive edges shall not be used. Hangers that
pinch the piping shall not be used.
2.7 Solvent Cement Joints.
2.7.1 SAFETY REQUIREMENTS AND PRE-
CAUTIONSi
(a) General. Solvents contained in CPVC plastic
pipe cements are classified as airborne contam-
inants and flammable and combustible liquids.
Precautions listed in this appendix should be
followed to avoid injury to personnel and the
hazard of fire.
(b) Prolonged breathing of s olvent vapors should be
avoided. When pipe and fittings are being joined
in partially enclosed areas, a ventilating device
should be used in such a manner to minimize the
entry of vapors into the breathing areas.
(c) Solvent cements should be kept away from all
sources of ignition, heat, sparks and open flame.
(d) Containers for solvent cements should be kept
tightly closed except when the cement is being
used.
(e) All rags and other materials used for mopping
up spills should be kept in a safety waste re-
ceptacle which should be emptied daily.

Most of the solvents used in CPVC pipe ce-
ments can be considered eye irritants and con-
tact with the eye should be avoided for it may
cause eye injury. Proper eye protection and the
use of chemical goggles or face shields are ad-
visable where the possibility of splashing exists
in handling solvent cements. In case of eye con-
tact, flush with plenty of water for 15 minutes
and call a physician immediately.
Repeated contact with the skin should be avoided.
Proper gloves impervious to and unaffected by
the solvents should be worn when frequent con-
tact with the skin is likely. Application of the sol-
vents or solvent cements with rags and bare hands
is not recommended. Brushes and other suitable
applicators can be used effectively for applying
the solvent cement, thus avoiding skin contact. In
the event of excessive contact, remove contami-
nated clothing and wash skin with soap and water.
Selection. Follow the manufacturer's recom-
mendations for type of solvent cements for such
conditions as temperatures over 100°F (38°C),
or humidity over 60%.
Handling (to maintain effectiveness). Pack-
age solvent cement in containers no larger than
1 quart (1 liter). Keep solvent cement can closed
and in the shade when not in use. Keep appli-
cator submerged in solvent cement between ap-
plications. Discard solvent cement when it
thickens appreciably or gels. Solvent cement
shall not be thinned.
Primer. A listed primer in compliance with
ASTM F 656 shall be used with CPVC solvent
cements that require the use of a primer. CPVC
solvent cements that do not require the use of a
primer are permitted for joints up to 2 inches in
size.
Size of Applicator. Applicator should be about
one half the pipe diameter. Do not use small ap-
plicator on large pipes.
2.7.6 Procedures
Step 1. Cut pipe square with hand saw and
mitre box, mechanical cutoff saw or
tube cutter designed for plastic.
Step 2. Ream and chamfer pipe (to eliminate
sharp edges, beads and all burrs).
Step 3. Clean all dirt, moisture and grease from
pipe and fitting socket. Use a clean, dry
rag.
Step 4. Check dry fit of pipe in fittings. Pipe
should enter fitting socket 14 to y4 of
socket depth. On larger sizes of Sch. 80
fittings, a looser fit may be expected.
This is a normal condition, and requires
care to apply an adequate amount of
cement.
Step 5. Apply CPVC primer, if required (See
Section 2.7.4) to inside of fitting
socket. Take care to avoid puddling.
Step 6. Apply CPVC primer, if required to
outside surface of pipe to depth of fit-
ting socket.
Step 7. When using solvent cements requiring
a primer wait until primer surface is
tacky. DO NOT attempt to soften (dis-
solve) the surface as is required for
PVC.
Step 8. Apply a liberal coat of CPVC solvent
cement to the outside surface of the
pipe to the depth of the fitting socket.
Step 9. Apply a light coat of CPVC solvent ce-
ment to inside of fitting socket. Apply
a second liberal coat of cement to the
pipe end. Take particular care in ce-
menting larger sizes of Sch. 80 fittings.
Be sure all surfaces are coated.
Step 10. While both the inside socket surface
and the outside surface of the pipe are
WET with solvent cement, forcefiilly

bottom the pipe in the socket, giving
the pipe a quarter turn while inserting,
if possible.
Step 11. Hold the joint together for 10 to 15
seconds to assure that the pipe remains
bottomed against the pipe stop.
Step 12. Do not disturb the joint for at least 30
minutes.
Note: The joint is weak until the ce-
ment is dry. If the joint is adjusted after
it is set, the joint will be ruined. See
Table 2 for recommended set time.

Step 13. Wipe excess cement from the pipe. A
properly made joint will show a bead
of cement around its entire perimeter.
Any gaps may indicate insufficient ce-
ment.
Step 14. The system shall not be pressurized
until the joints have cured (set) at
least as long as recommended by the
manufacturer. If the manufacturer's
recommendation is not available, the
following cure times are required.
2.7.7 Prohibited Joints. Piping shall not be threaded.
Female screwed fittings, with CPVC threads,
shall be prohibited. Joints made with adhesives
shall be prohibited.
2.7.8 Threaded Joints. When threads are required,
molded male adapters shall be used.
2.7.9 Location. CPVC threaded joints shall be ac-
cessible.
2.7.10 Lubricants. Only thread tape or thread lubri-
cant approved specifically for use with CPVC
shall be used. Conventional pipe thread com-
pounds, putty, linseed oil based products, and
unknown mixtures are prohibited.
2.7.11 Tightening. Joints shall be tightened approxi-
mately 1 Vi turns past hand tight.
CAUTION: Hand tight refers to the number of
threads to reach hand tight with metal pipe.
Small sizes of CPVC can be bottomed by hand
pressure alone. DO NOT overtighten.

2.7.12 SpecialJoints.
2.7.12.1 Transition Joints. Transitions from CPVC tub-
ing to metal piping and valves shall be made
only with listed transition fittings suitable for
that purpose. When required, the transition fit-
tings shall be designed in such a manner that it
can be anchored to a building member to pre-
vent rotation. [UPC 316.2]
Soldering. Soldered metal joints shall not be
made closer than 18 inches (457 mm) to any al-
ready installed plastic to metal adapter in the
same water line.
Hose Bibbs. Hose bibbs shall be connected
only to metal system components which are ad-
equately anchored to the building structure. The
CPVC plastic system shall terminate in wall.
Pressure Relief Valves.
CPVC Piping. CPVC piping used for temper-
ature and/or pressure relief valve drain lines
shall be graded to the outlet end and shall be
supported at 3 foot (914 mm) intervals both ver-
tically and horizontally.
2.9 Installation, Inspection and Testing.
2.9.1 Finish Nipples. Finish nipples shall be con-
nected to drop ear elbows or other fittings listed
for preventing rotation. Finish nipples shall not
be CPVC but CPVC stub outs for fixture con-
nections shall be permitted. [UPC 609.0]
2.9.2 Location. CPVC tubing shall not be installed so
as to be subjected to direct sunlight after instal-
lation, and shall not be installed on the surface of
the building unless it is protected by paint or a
protective covering.
2.9.3 Water Heaters. There shall be a minimum of
six (6) inches (152 mm) of metalHc piping be-
tween a gas water heater connection and CPVC
tubing. CPVC tubing may be installed down-
stream of instantaneous (coil or immersion)
water heaters provided that the water heater
temperature controls are maintained for maxi-
mum temperature of 1 80"" F.
2.9.4 Under Slab. Pipe shall be installed in trench
with uniform support. Trenches shall be back-
filled to a depth of six (6) inches (152 mm) with
clean earth, sand or other approved material
which shall not contain sharp rocks, boulders,
cinder fill or other materials which would dam-
age or break the piping. Pipe shall be stubbed
up and all ends shall be capped. The system
shall be filled with water and all air shall be bled
off. The system shall be pressure tested under a
water pressure which is not less than the work-
ing pressure which is not less than the working
pressure under which it is to be used for a min-
imum of two (2) hours. All leaks shall be cor-
rected. Foam pipe insulation shall be installed
on all stub ups to prevent damage during con-
crete pour and finishing.

Identification. A permanent sign with the legi-
ble words "This building has non-metallic inte-
rior water piping" shall be fastened on or inside
the main electric service panel.
Position of Marking. When installed, piping
and fittings shall be positioned so that when
practical, identifying markings shall be readily
visible for inspection.
Testing. Air testing is prohibited.
Sizing.
Method. Piping shall be sized in accordance
with UPC Section 610.0. When Appendix A is
applicable, use Chart 1 or 2 as appropriate.
Flow velocities shall be limited to a maximum
of 8 feet per second (2.4 m/s). See Table 3.

2.3 Joints.
2.3.1 General Information. Copper tube and fittings
maybe joined in a number of ways, depending on
the purpose of the system. Soldering and brazing
with capillary fittings are the methods used most.
2010 CALIFORNIA PLUMBING CODE
433
WELDED COPPER AND COPPER ALLOY WATER TUBE
The American Welding Society defines soldering
as a joining process which takes place below
840°F (449''C) and brazing as a similar process
which occurs above 840°F (449''C) but below the
melting point of the base metals. In actual practice
for copper systems, most soldering is done at tem-
peratures ranging from about SSO'^F to 550°F
(177° to 288°C), while most brazing is done at
temperatures ranging from 1100° F to 1500°F
(593°C to 816°C). The choice between soldering
or brazing will generally depend on operating con-
ditions. Solder joints are generally used where the
service temperature does not exceed 205°F (96°C),
while brazed joints can be used where greater
strength is required, or where system temperatures
are as high as 400°F (204°C). [UPC 316.1]
2.3.2 Fittings for Soldered, Brazed, and Flared
Joints. Fittings are available in all standard tube
sizes and in a wide variety of types to cover needs
for plumbing. They can be either soldered or
brazed, although brazing cast fittings requires care.
Wrought copper pressure fittings are also available
over a wide range of sizes and types. These, too,
can be joined by either soldering or brazing, and
wrought fittings are preferred where brazing is the
joining method. Otherwise, the choice between
cast and wrought fittings is largely a matter of the
user's preference. Flared-tube fittings provide
metal-to-metal contact similar to ground joint
unions; both can be easily taken apart and re-
assembled. They are especially useful where resid-
ual water cannot be removed from the tube and
soldering is difficult. Flared joints may be required
where a fire hazard exists and the use of a torch to
make soldered or brazed joints is not allowed.
2.3.3 Solders.
Note: Users of the Uniform Plumbing Codes are
reminded that provisions of the Federal Clean
Drinking Act of 1986, which all must obey, forbid
the use of solder which contains in excess of 0.2%
of lead, by weight in potable water systems. The
provisions of the act are incorporated in all ordi-
nances, statutes, state and municipal regulations
by reference and by operation of law.
The selection of a solder depends on the operating
pressure and temperature of the line. Considera-
tion should also be given to the stresses on the joint
caused by thermal expansion and contraction.
However, stresses due to temperature changes
should not be significant in two commonly en-
countered cases: when tube lengths are short, or
when expansion loops are used in long tube runs.
Solder is generally used in wire form, but paste-
type solders are also available. These are finely
granulated solders in suspension in a paste flux.
When using paste-type solders, observe these four
rules:
1 . Wire solder must be applied in addition to the
paste to fill the voids and assist in displacing
the flux, otherwise the surfaces may be well
"tinned" and yet there may not be a good
joint with a continuous bond.
2. The paste mixture must be thoroughly stirred
if it has been standing in the can for more
than a very short time, as the solder has a ten-
dency to settle rapidly to the bottom.
3. The flux cannot be depended on to clean the
tube. Cleaning should be done manually as is
recommended for any other flux and solder.
4. Remove any excess flux.
Solders are available containing small amounts of
silver or other additives to impart special proper-
ties. Such solders may require special fluxes. The
manufacturer's recommendations should be con-
sulted regarding proper procedures and fluxes for
such solders and about the expected properties.
2.3.4 Soldering Flux.
The functions of the soldering flux are to remove
residual traces of oxides, to promote wetting, and
to protect the surfaces to be soldered from oxida-
tion during heating. The flux should be applied to
clean surfaces and only enough should be used to
lightly coat the areas to be joined.
An oxide film may reform quickly on copper after
it has been cleaned. Therefore, the flux should be
applied as soon as possible after cleaning.
CAUTION
Careless workmanship, especially during flux ap-
plications, can result in corrosion of the tube long
after the system has been installed. If excessive
flux is used, the residue inside the tube can cause
corrosion. In an extreme case, such residual flux
can actually lead to perforation through the tube
wall causing leakage. To guard against this dan-
ger, it is important (1) to choose a flux that is not
too corrosive, and (2) to use only the minimum
amount actually needed to make the joint.
2.3.5 Solder Joints.
Soldering and brazing both involve basic steps,
which must be executed with care and craftsman-
ship. The steps are:
(1) Measuring
(2) Cutting
(3) Reaming
(4) Cleaning
(5) Fluxing
(6) Assembly and support
(7) Heating
(8) Applying the filler metal
(9) Cooling and cleaning
434
2010 CALIFORNIA PLUMBING CODE
WELDED COPPER AND COPPER ALLOY WATER TUBE
Each step contributes to a strong, dependable
joint.
2.3.5.1 Measuring.
Measuring the length of each tube segment must
be accurate. Inaccuracy can compromise joint
quality. If the tube is too short it will not reach all
the way into the socket of the fitting and a proper
joint cannot be made. If the tube segment is too
long, there is danger of cocking the tube in the fit-
ting and putting strain on the system which could
affect service life.
2.3.5.2 Cutting.
Once the tube is measured it can be cut. Cutting
can be accomplished in a number of different
ways to produce a satisfactory square end. The
tube can be cut with a disc-type tube cutter, a
hacksaw, an abrasive wheel, or with a stationary
or portable handsaw. Care must be taken that the
tube is not deformed while being cut. Regardless
of method, the cut must be square with the run of
the tube so that the tube will seat properly in the
fitting socket.
2.3.5.3 Reaming.
All pipe and tube shall be reamed to the full I.D.
of the pipe and tube.
Tools used to ream tube ends include the reaming
blade on the tube cutter, half-round or round files,
a pocket knife, and a suitable deburring tool. With
annealed tube, care must be taken not to deform
the tube end by applying too much pressure. Both
the inside and the outside of the tube may require
removal of the burr.
2.3.5.4 Cleaning.
The removal of oxides and surface soil is crucial
if filler metal is to flow properly into the joint. Un-
removed oxide, surface soil, and oil can interfere
with the strength of the joint and cause failure.
Mechanical cleaning is a simple operation. The
end of the tube should be abraded lightly using
sand cloth or nylon abrasive pads for a distance
only slightly more than the depth of the fitting
socket. The socket of the fitting should also be
cleaned using sand cloth, abrasive pads, or a prop-
erly sized fitting brush.
Copper is a relatively soft metal. If too much ma-
terial is removed, a loose fit will result and inter-
fere with satisfactory capillary action in making the
joint. The capillary space between the tube and fit-
ting is approximately 0.004 inch (0.1 mm). Solder
or brazing filler metal can fill this gap by capillary
action. This spacing is critical for the filler metal to
flow into the gap and form a strong joint.
Surfaces, once cleaned, should not be touched with
bare hands or oily gloves. Skin oils, lubricating
oils, and grease impair solder flow and wetting.
2.3.5.5 Fluxing.
Stir the flux before use. A good flux will dissolve
and remove traces of oxide from the cleaned sur-
faces to be joined, protect the cleaned surfaces
from reoxidation during heating and promote wet-
ting of the surfaces by the solder. A thin, even
coating of flux should be applied with a brush to
both tube and fitting. Do not apply with fingers.
Chemicals in the flux can be harmfiil if carried to
the eyes or open cuts.
2.3.5.6 Assembly and Support.
After both tube and fitting surfaces are properly
fluxed, they should be assembled, making sure the
tube seats against the base of the fitting socket. A
slight twisting mofion ensures even distribution
by the flux. Remove excess flux. Care must be
taken to assure that the tube and fittings are prop-
erly supported with a uniform capillary space
around the entire circumference of the joint. Uni-
formity of capillary space will ensure good filler
metal penetration if the guidelines of successfiil
joint making are followed. Excessive joint clear-
ance can cause the filler metal to crack under
stress or vibration.
The joint is now ready for soldering. Joints pre-
pared and ready for soldering should be completed
the same day and not left unfinished overnight.
2.3.5.7 Heating.
Because an open flame may be used for solder-
ing, and because flammable gases are used, safety
precautions must be observed. The heat is gener-
ally applied using an air/fuel torch. Such torches
use acetylene or an LP gas. Electric resistance
tools can also be used.
Heating should begin with the flame perpendicular
to the tube. The copper tube conducts the initial
heat into the fitting socket for even distribution of
heat inside and out. The extent of this preheating
depends upon the size of the joint. Experience will
indicate the amount of time needed. The flame
should now be moved onto the fitting. Then move
the flame from the fitting socket back onto the tube
a distance equal to the depth of the fitting socket.
Touch the solder to the joint. If the solder does not
melt, remove it and continue the heating process.
Be careful not to overheat or to direct the flame
into the fitting cup. This could cause the flux to
bum and destroy its effectiveness. When the melt-
ing temperature of the solder has been reached,
heat may be applied to the base of the cup to aid
capillary action in drawing the solder into the cup.
2.3.5.8 Applying the Filler Metal.
For tube in a horizontal position, start applying
the solder slightly off-center at the bottom of the
joint. Proceed across the bottom of the fitting and
up to the top center position. Return to the point of
2010 CALIFORNIA PLUMBING CODE
435
WELDED COPPER AND COPPER ALLOY WATER TUBE
beginning, overlap the starting point, and then
proceed up the incompleted side to the top, again,
overlapping the solder.
For joints in the vertical position, a similar se-
quence of overlapping passes should be made,
starting wherever is convenient. Molten solder
will be drawn into the joint by capillary action re-
gardless of whether the solder is being fed up-
ward, downward, or horizontally.
2.3.5.9 Cooling and Cleaning.
After the joint has been completed, natural cool-
ing is best. Shock cooling with water may cause
unnecessary stress on the joint and resuh in even-
tual failure. When cool, clean off any remaining
flux with a wet rag.
2.3.6 Brazed Joints.
Brazing is the second most commonly used
method for joining copper tube. Making brazed
joints is similar to making soldered joints with re-
spect to measuring, cutting, reaming, cleaning, as-
sembly and support. And as in soldering, the
brazing filler metal is melted by the heat of the
tube and fitting and drawn into the joint by capil-
lary action. [UPC 3 16. 1 .7]
The major differences between soldering and
brazing are the:
• Type of flux used,
• Composition of filler metal, and
• Amount of heat required to melt the filler metal.
2.3.6.1 Brazing Flux.
The fluxes used for brazing copper joints are dif-
ferent in composition from soldering fluxes. The
two types cannot be used interchangeably. Braz-
ing fluxes are water based, whereas most solder-
ing fluxes are petroleum based. Similar to
soldering fluxes, brazing fluxes dissolve and re-
move residual oxide from the metal surface, pro-
tect the metal from reoxidation during heating and
promote wetting of the surfaces to be joined by
the brazing filler metal.
Fluxes also provide the draftsman with an indica-
tion of temperature. Application of the flux is the
same as when soldering. If the outside of the fit-
ting and the heat-affected area of the tube are cov-
ered with flux (in addition to the end of the tube
and the cup), oxidation will be prevented and the
appearance of the joint will be greatly improved.
2.3.6.2 Brazing Filler Metals.
There are two general types of brazing filler metal
used for joining copper tube. Classified according
to their components, they are: BCuP (Brazing-
Copper-Phosphorous) and BAg (Brazing- Silver).
BCuP filler metals are preferred for joining copper
tube and fittings. The phosphorous in them acts as
a fluxing agent and the lower percentage of silver
makes them relatively low cost. When using cop-
per tube, wrought copper fittings, and BCuP braz-
ing filler metal, fluxing is optional. However,
when cast fittings are brazed, flux must be used.
2.3.6.3 Heating.
Oxy/fuel torches are generally used for brazing
because of the higher temperatures required.
Recent innovations in tip design make air/fuel
torches useful on a wider range of sizes for braz-
ing.
When working at brazing temperatures, safety
precautions must be followed and care taken to
protect both the operator and the materials being
used.
The heating operation is the same as for solder-
ing. First preheat the tube and then the tube and
fitting. When the filler metal starts to melt, apply
heat at the base of the fitting socket to help draw
the brazing filler metal in by capillary action.
2.3.6.4 Applying Brazing Filler Metal.
Remember to allow the heat of the joint, not the
flame, to melt the filler metal. The melted filler
metal will be drawn into the joint by capillary ac-
tion. It is very important that the flame be in con-
tinuous motion. It must not be allowed to remain
on any one point long enough to bum through the
tube or fitting.
If the filler metal fails to flow, or has the tendency
to ball-up, it indicates either that there is oxide on
the surfaces being joined or that the parts to be
joined are not hot enough. If the filler metal re-
fuses to enter the joint, the fitting cup is not hot
enough. If it tends to flow over the outside of ei-
ther part of the joint it indicates that part is over-
heated. When the joint is completed, a continuous
fillet should be visible completely around the
joint.
Large diameter tube is more difficult to heat to the
desired temperature. The use of a heating tip or
rosebud may be necessary to maintain the proper
temperature over the area being brazed. Once total
heat control is attained, follow the same proce-
dures used for smaller tube.
2.3.6.5 Cooling and Cleaning.
When the brazed joint is finished, allow it to cool
naturally. Flux residues and some oxides formed
by heating can be removed by washing with hot
water and brushing with a stainless steel wire
brush.
2.3.7 Flared Joints.
2.3.7.1 Flared Joints with Impact Flaring Tools:
Step 1 Cut the tube to the required length.
Step 2 Remove all burrs. This is very important
to assure metal-to-metal contact.
436
2010 CALIFORNIA PLUMBING CODE
WELDED COPPER AND COPPER ALLOY WATER TUBE
Step 3 Slip the coupling nut over the end of the
tube.
Step 4
Step 5
Step 6
Insert flaring tool into the tube end.
Drive the flaring tool by hammer strokes,
expanding the end of the tube to the de-
sired flare. This requires a few moder-
ately light strokes.
Assemble the joint by placing the fitting
squarely against the flare. Engage the cou-
pling nut with the fitting threads. Tighten
with two wrenches, one on the nut and one
on the fitting. [UPC 606. 1.1]
2.3.7.2 Flared Joints with Screw-Type Flaring Tools:
Steps 1-3 Same as for impact flaring previously
described.
Step 4 Clamp the tube in the flaring block so
that the end of the tube is slightly above
the face of the block.
Step 5 Place the yoke of the flaring tool on the
block so that the beveled end of the
compressor cone is over the tube end.
Step 6 Turn the compressor screw down firmly,
forming the flare between the chamber
in the flaring block and the beveled
compressor cone.
Step 7 Remove the flaring tool. The joint can
now be assembled as in Step 6 for im-
pact flaring. [UPC 606.2.1]
2.4 Sizing,
2.4.1 Velocity.
Note: There are various hydraulic formulas for
the flow of water in pipe. With high velocity and
attendant turbulent flow, there can be excessive
noise and piping wear.
The designer should aim for maximum flow ve-
locities in the range of 5 to 8 feet per second (1.5-
2.4 meters per second) to minimize noise and ero-
sion problems. For the smallest tube sizes, the de-
signer is wise to work at the bottom of this range,
as a maximum, to guard against local high veloci-
ties building up due to faulty workmanship (e.g.
burrs at tube ends which are not properly reamed)
or unusually numerous changes in flow direction.
3.0 GENERAL INFORMATION.
3.1 It is not possible to cover all the variables of a
plumbing system; however, the following infor-
mation may prove helpful:
3.2 Expansion Loops - Copper tube, like all piping
materials, expands and contracts with temperature
changes. Therefore, in a copper tube system sub-
jected to excessive temperature changes, the line
tends to buckle or bend when it expands unless
compensation is built into the system. Severe
stresses on the joints may also occur. Such stresses,
buckles, or bends are prevented by the use of ex-
pansion joints or by installing offsets, "U" bends,
coil loops, or similar arrangements in the tube as-
sembly. These specially shaped tube segments take
up expansion and contraction without excessive
stress. The expansion of a length of copper tube
may be calculated from the formula:
Temperature Rise (^F) x length (feet) x
12 (inches per foot) x
Expansion Coefficient (inch per inch per "^F) = Expansion
(inches), or
Temperature Rise (^C) x Length (meter) x J 000 (mm per
meter) x Expansion Coefficient
(mm per mm per °C) = Expansion (mm).
Calculations for expansion and contraction should
be based on the average coefficient of expansion
of copper which is 0.0000094 per degree F (1.692
X 10-5 per degree C), between 70°F and 212°F
(21°C and 100°C). For example, the expansion of
each 100 feet (30.5 meters) of length of any size
tube heated from room temperature (70°F) to
170^F (a lOO^F (55.6°C) rise) is 1.128 inches
(28.7 mm).
IOO''Fx 100 feet X 12 inch/foot x 0.0000094 inch/inch/^F =
1.128 inch, or
55.6°Cx 30.48 mm x 1000 mm/m x 1.692 x 10-5 mm/mm/^C
= 28. 7 mm
3.3 Tube Supports - See Section 314.0 and Table
3-2 of the Uniform Plumbing Code.
3.4 Bending - Copper tube, properly bent, will not col-
lapse on the outside of the bend and will not buckle
on the inside of the bend. Tests demonstrate that the
bursting strength of a bent copper tube can be
greater than it was before bending. Because copper
is readily formed, expansion loops and other bends
necessary in an assembly are quickly and simply
made if the proper method and equipment are used.
Simple hand tools employing mandrels, dies,
forms, and fillers, or power-operated bending ma-
chines, are used.
3.4.1 Both annealed tube and bending-temper tube can
be bent with hand benders. The proper size bender
for each size tube must be used. Usually the size
of the tool corresponds to the nominal outside di-
ameter of the tube, not the standard tube size. For
a guide to the typical bend radii, see the following
bending guide for copper tube.

lows:
I. Preliminary Steps
Inspect the inside of the sewer Une using a tel-
evision camera and video tape recorder to as-
certain the line condition. Mark the details
revealed by the video inspection including:
1 . The ground surface to show the location of
the lateral tie of the city wye.
2. The line location with an arrow in the street
pointing back at the lateral.
3 . The property denoting the lateral location.
4. The locations of the proposed excavations.
Obtain utility line identification service contact
information and all applicable permits.
II. Excavation
In addition to the above markings, the local util-
ity companies will mark utilities. Considerations
are soil density; clearance from obstacles, utili-
ties, and structures; location of bends; and water
service locations. Excavations and shoring shall
be in accordance with jurisdictional safety re-
quirements.
III. Set Up
Fuse the proper length of polyethylene pipe in
accordance with ASTM D 2657 and fuse the end
to a small length that is attached to the pulling
head. A rod pusher cable is pushed through the
damaged host pipe and attached to the pulling
cable, which is then drawn through the pipe. The
clevis end of the cable is attached to the pulling
head. The pulling equipment is then set up ac-
cording to the manufacturers instructions.
IV. Pulling
Pull the pulling head through. Once the pull is
done, complete the connection to the existing
piping.
2.5 Cleanouts.
Cleanouts shall be installed in accordance with
UPC Section 707.0.
2.6 Inspections.
The completed piping shall be internally in-
spected by television camera unless waived by
the Administrative Authority. [UPC 103.5]

chored rigidly to a support, but shall be secured
with hangers or straps that provide for a degree of
movement and that prevent damage to the tubing.
Do not use hangers or straps with sharp or abra-
sive edges. Do not use hangers that pinch the pip-
ing. [UPC 314.0]
2.7 Inspection and Testing.
A. Inspection. All tubing shall be properly seated
on to the fitting per the manufacturer's instructions.
For crimp fittings, each crimped joint shall be
checked. Buckled, gouged, or obviously damaged
pipe shall not be used. Consult manufacturer's rec-
ommendations for repair procedures.
B. Testing. Upon completion of a section or of the
entire hot and cold water supply system it shall be
tested and proved tight under a water pressure or
air test not less than the working pressure under
which it is to be used. The water used for tests
shall be obtained from a potable source. The sys-
tem shall withstand the test without leaking for a
period of not less than fifteen (15) minutes.
2.8 Joints and Connections.
2.8.1 Procedure. Piping should be cut with a pipe cut-
ter designed specifically for composite pipe. Pip-
ing shall be cut square, i.e. perpendicular to the
length. No other cutting methods shall be used
and care must be taken to remove any excess ma-
terial, flashing, or burrs.
2.8.2 Tools. Fitting manufacturer's recommended tool
shall be used with the composite insert fitting sys-
tems. For specific procedures, follow the manu-
facturer's recommendations.
2.8.3 Transition Joints.
2.8.3.1 Fittings. Transitions for composite tubing to
metal piping or valves shall be made only with
transition fittings intended for that purpose.
2.8.4 Joints. Joints shall not be allowed in piping in-
stalled in or under a concrete slab resting on grade
unless for repair within a building structure. All
repair joints must be properly protected with a
heat shrink sleeve. All slab penetrations shall be
sleeved.

used for temperature and/or pressure relief valve
drain lines shall be graded to the outlet end and
shall be supported at a maximum of 8 ft. 2 in.
(2,489 mm) interval horizontally. Vertical piping
shall be supported at every floor. Vertical piping
shall have a mid-story guide.
2.10 Installation.
2.10.1 Bends. Piping shall be installed by bending the
composite pipe by hand to a minimum radius of 5
times the nominal pipe diameter. External bend
supports or sleeves are not required as the com-
posite piping is rigid after bending.

2010 CALIFORNIA PLUMBING CODE
COMPOSITE PEX-AL-PEX HOT AND
PE-AL-PE COLD WATER-DISTRIBUTION SYSTEMS
2.10.2 Damage. Kinked, buckled, gouged, or other ob-
vious damaged pipe shall not be used.
2.10.3 Finish Nipples. Finish nipples shall be connected
to drop ear fittings to prevent rotation. Finish nip-
ples shall not be PEX.
2.10.4 Hose Bibs. The piping directly connected to any
hose bib shall be so anchored that the load on the
hose bib will not strain the composite piping.
2.10.5 Heated Joints. An open flame shall not be ap-
plied to PEX-AL-PEX or PE-AL-PE piping when
brazing, soldering, or welding joints.
2.10.6 Working Pressure and Temperature. Long term
working pressures for the PEX-AL-PEX shall not
exceed a maximum of 125 psi (860 kPa) and the
long term working temperature shall not exceed
180°F (82'^C). Long term working pressures for
the PE-AL-PE shall not exceed a maximum of
100 psi (690 kPa) and the long term working tem-
perature shall not exceed 180°F (82°C).
2.10.7 Exposure to Sunlight. Only UV stabihzed com-
posite piping can be subjected to direct sunlight
after installation and can be installed on the sur-
face of the building. Composite pipe contains an
ultraviolet (UV) inhibitor to withstand limited ex-
posure to UV light. Manufacturer's recommends
placing the unused portion of a coil back in the
product's box rather than storing in the sunlight
while not in use.
2.10.8 Water Heater Connections. PEX-AL-PEX or
PE-AL-PE piping shall not be installed within the
first eighteen inches (18) (457 mm) of piping con-
nected to a water heater. [UPC 604. 13.2]
2.10.9 Water Hammer Arrestors. A composite hot
water system will withstand repeated pressure
surges, well in excess of its rated pressure. The
Uniform Plumbing Code requires a means of at-
tenuating water hammer. Consequently, water
hammer arrestors shall be required when solenoid
valves or other quick closing devices are used in
the system. In designing for such situations, it is
advisable to consult the pipe or fittings manufac-
turer for recommended surge pressure limits.
Water hammer and surge pressure calculations are
reviewed in Chapter 7, AWWA Manual M-11.
[UPC 609.10]
2.11 Sizing.
2.11.1 Method. Piping shall be sized in accordance with
UPC Section 610.0.
When UPC Appendix A is applicable, use Table
2. Add equivalent lengths from Table 3 when de-
termining developed length.
Maximum velocities through PEX-AL-PEX and
PE-AL-PE copper alloy fittings shall be limited to
eight (8) feet per second (fps) (2.4 mps) in cold
water and five (5) feet per second (fps) (1 .52 mps)
in hot water. [UPC 610.0]

shall be marked with the designated lAPMO
certification mark to show compliance with this
standard.
3.0 PROTECTION OF HOSES.
3.1 Storage. Unprotected hose shall not be stored in
direct sunlight. The hose shall be stored in a way
to protect it from mechanical damage (slitting,
puncturing, etc.). Exposure to sunlight during nor-
mal construction periods is not harmful. PVC sol-
vent cement shall be stored in a cool place, except
when actually in use at the job site. The solvent
cement manufacturer's specific storage recom-
mendations shall be followed.
3.2 Thermal Expansion. Hose shall be "snaked" in
the trench bottom with enough slack, at least 6 in.
(152.4 mm) per 100 ft. (30.5 m), to compensate for
thermal expansion and contraction before stabiliz-
ing hose. Stabilize hose by bringing it approxi-
mately to operating temperature before testing and
backfilling by one of the following methods:
(a) Backfill with a layer of soil for shading.
(b) Fill with water at operating temperature.
(c) Allow to stand overnight.
3.3 Exposed Hose. Hose above grade when located
on the exterior of the building or structure shall be
protected from mechanical damage to the satis-
faction of the Administrative Authority. Where ex-
posed to sunlight, the hose shall be wrapped with
at least 0.040 in. (1.0 mm) of tape or other ap-
proved method acceptable to the Administrative
Authority.
4.0 TRENCHING, COVER, AND BACKFILL.
4.1 Trenching and Cover. Trench bottoms shall be
uniformly graded and shall be of either undis-
turbed soil or shall consist of a layer or layers of
compacted backfill so that minimum settlement
will take place.
4.2 Backfill. Selected backfill shall be used to pro-
vide firm continuous support and proper com-
paction. Backfill over hose, except that joints shall
be left exposed. After inspection and pressure test,
complete backfill to a minimum of 12 in. (0.3 m)
cover.

Solvent Cement Joints.
Selection. Solvent cement shall be recommended
for flexible PVC hose by the manufacturer. Follow
manufacturer's recommendations for types of sol-
vent cement for flexible PVC hose.
Handling (to maintain effectiveness). Use sol-
vent cement in containers no larger than 1 quart
(1 liter). Keep solvent cement can closed and in
the shade when not in use. Keep applicator sub-
merged in solvent cement between application.
When solvent cement becomes thicker, THROW
IT AWAY. Solvent cement shall NOT be thinned.
Size of Applicator. Follow manufacturer's rec-
ommendations.
Application. Follow manufacturer's recommen-
dations.
General Principles.
To consistently make good joints, the following
should be clearly understood and adhered to:
(a) The joining surfaces must be softened (dis-
solved) and made semi-fluid.
(b) Sufficient cement must be applied to fill the
gap between hose and fitting.
(c) Assembly of hose and fittings must be made
while the surfaces are still wet and fluid.
(d) Joint strength develops as the cement dries.
In the tight part of the joints the surfaces will
tend to fiise together; in the loose part the ce-
ment will bond to both surfaces.
(e) When solvent welding flexible PVC hose to
other than PVC fittings, follow manufac-
turer's installation instructions.
Penetration and dissolving can be achieved by the
cement itself, by a suitable primer, or by the use of
both primer and cement. A suitable primer will
penetrate and dissolve the plastic more quickly
than cement alone. In cold weather more time and
additional applications are required (see Figure 1).
FIGURE 1
AREAS OF HOSE AND FITTINGS TO BE SOFTENED
(DISSOLVED) AND PENETRATED
5.1,5.3 More than sufficient cement to fill the loose part
of the joint must be applied (see Figure 2). Be-
sides filling the gap, adequate cement layers will
penetrate the surfaces and also remain wet until
the joint is assembled.
FIGURE 2
CEMENT COATINGS OF SUFFICIENTTHICKNESS
5.1.5.4
If the cement coatings on the hose and fittings are
wet and fluid when assembly takes place, they
will tend to flow together and become one cement
layer. Also, if the cement is wet the surfaces be-
neath them will still be soft, and these dissolved
surfaces in the tight part of the joint will tend to
fuse together (see Figure 3).
FIGURE 3
ASSEMBLY OF SURFACES WHILE THEY ARE WET AND SOFT
5.1.5.5
As the solvent dissipates, the cement layer and the
dissolved surfaces will harden with a correspon-
ding increase in joint strength. A good joint will
take the required working pressure long before the
joint is fully dry and final strength is obtained. In
the tight (fused) part of the joint, strength will de-
velop more quickly than in the looser (bonded)
part of the joint. Completed joints should not be
disturbed until they have cured sufficiently to
withstand handling. Joint strength develops as the
cement dries. Information about development of
bond strength of solvent cemented joints is avail-
able (see Figure 4).

5.1.6 Procedure.
Note: Do not take SHORTCUTS. Most failures are
caused by short cuts. DON'T TAKE A CHANCE.
Step 1 Cut hose square with hand saw and miter
box, mechanical cut-off saw, or tube cut-
ter designed for plastic.
Step 2 Ream and chamfer hose (to eliminate
sharp edges, beads and all burrs).
Step 3 Clean all dirt, moisture, and grease from
hose and fitting socket. Use a clean, dry
rag.
Step 4 Check dry fit of hose in fitting. Hose
should enter fitting socket from !/3 to %
depth of socket.
Step 5 Soften inside socket surface by applying
an aggressive primer which is a true sol-
vent for PVC and is recommended by
the manufacturer.
Step 6 Soften mating outside surface of hose to
depth of socket by applying a liberal coat
of the (aggressive) primer. Be sure entire
surface is softened.
Step 7 Again coat inside socket surface with the
(aggressive) primer. Then, without delay,
apply solvent cement liberally to outside
of hose. Use more than enough to fill any
gaps.
Step 8 Apply a light coat of PVC solvent cement
to inside of socket using straight outward
strokes (to keep excess solvent out of
socket). This is also to prevent solvent ce-
ment damage to hose. For loose fits, apply
a second coat of solvent cement. Time is
important at this stage. (See 5.1.4)
Step 9 While both the inside socket surface and
the outside surface of the hose are SOFT
and WET with solvent cement, forcefully
bottom the hose in the socket, giving the
hose a one-quarter turn, if possible. The
hose must go to the bottom of the socket.
Step 10 Hold the joint together until tight.
Step 11 Wipe excess cement from the hose. A
properly made joint will normally show
a bead around its entire perimeter. Any
gaps may indicate insufficient cement or
the use of light bodied cement on larger
diameters where heavy bodied cement
should have been used.
Step 12 Do not disturb joint for the following pe-
riods:
30 minutes minimum at 60°F to lOO^F
(16°Cto38^C)
5.1.7
5.1.7.1

4 hours minimum at 0°F to 20°F (-18°C
to -TC)
Handle the newly assembled joints care-
fully during these periods. If gaps (step
11) or loose fits are encountered in the
system, double these periods.
Step 13 The system shall not be pressurized until
the joints have cured (set) at least as long
as recommended by the manufacturer. If
manufacturer's recommendation is not
available, the cure times as shown in
Table 1 are required.
Installation and Testing.
Installation. The hose shall be properly supported
to prevent excessive sagging.
Testing.
(a) All pool, spa, and hot tub piping shall be in-
spected and approved before being covered or
concealed, except as permitted by Sections 3.2
and 4.2. It shall be tested and proved tight to
the satisfaction of the Administrative Author-
ity, under a static water or air pressure test of
not less than 35 psi (241 kPa) for 15 minutes.
Exception: All exposed equipment need not
be tested as required in this section.
(b) All swimming pool, spa, or hot tub installa-
tions must be completed, filled with water,
and in operation before final inspection.
SAFETY REQUIREMENTS AND PRECAU-
TIONS*
General. Solvents contained in PVC plasfic hose
cements are classified as airborne contaminants
and flammable and combustible liquids. Precau-
tions listed in this section should be followed to
avoid injury to personnel and the hazard of fire.
SAFETY PRECAUTIONS
1 . Prolonged breathing of solvent vapors should
be avoided. When hose and fittings are being
joined in partially enclosed areas, a ventilating
device should be used in such a manner to
minimize the entry of vapors into the breathing
areas.
2. Solvent cements should be kept away from all
sources of ignition, heat, sparks and open flame.
3. Containers for solvent cements should be
kept tightly closed except when the cement
is being used.
4. All rags and other materials used for mopping
up spills should be kept in a safety waste re-
ceptacle which should be emptied daily.
'CAUTION: Primers are toxic. Don't allow them to touch skin. Suitable gloves are advised.

A It is important to note that at temperatures colder thatn 20°F (-6.7°C) on sizes that exceed 3 in. (76.2 mm), test resuhs indicate that many variables exist
in the actual cure rate of the joint. The data expressed in these categories represent only estimated averages. In some cases, cure will be achieved in less
time, but isolated test results indicate that even longer periods of cure may be required.
B These cure schedules are based on laboratory test data obtained on Net Fit Joints (NET FIT = in a dry fit the pipe bottoms snugly in the fitting socket with-
out meeting interference). The relative humidity in these tests was 50% or less. Higher relative humidity may require longer cure periods.
5 . Most of the solvents used in PVC hose cements
can be considered eye irritants and contact with
the eye should be avoided for it may cause eye
injury. Proper eye protection and the use of
chemical goggles or face shields is advisable
where the possibihty of splashing exists in han-
dling solvent cements. In case of eye contact,
flush with plenty of water for 15 min. and call
a physician immediately.
6. Repeated contact with the skin should be
avoided. Proper gloves impervious to and un-
affected by the solvents should be worn when
frequent contact with the skin is likely. Appli-
cation of the solvents or solvent cements with
rags and bare hands is not recommended.
Brushes and other suitable applicators can be
used effectively for applying the solvent ce-
ment, thus avoiding skin contact. Li the event
of excessive contact, remove contaminated
clothing and wash skin with soap and water.

APPENDIX K
PRIVATE SEWAGE DISPOSAL SYSTEMS
K 1.0 Private Sewage Disposal - General.
(A) Where permitted by Section 713.0, the building sewer
shall be permitted to be connected to a private sewage dis-
posal system complying with the provisions of this ap-
pendix. The type of system shall be determined on the
basis of location, soil porosity, and groundwater level, and
shall be designed to receive all sewage from the property.
The system, except as otherwise approved, shall consist of
a septic tank with effluent discharging into a subsurface
disposal field, into one (1) or more seepage pits, or into a
combination of subsurface disposal field and seepage pits.
The Authority Having Jurisdiction shall be permitted to
grant exceptions to the provisions of this appendix for
permitted structures that have been destroyed due to fire
or natural disaster and that cannot be reconstructed in
compliance with these provisions provided that such ex-
ceptions are the minimum necessary.
(B) Where the quantity or quality of the sewage is such that
the above system cannot be expected to function satis-
factorily for commercial, agricultural, and industrial
plumbing systems; for installations where appreciable
amounts of industrial or indigestible wastes are produced;
for occupancies producing abnormal quantities of sewage
or liquid waste; or when grease interceptors are required
by other parts of this code, the method of sewage treat-
ment and disposal shall be first approved by the Author-
ity Having Jurisdiction. Special sewage disposal systems
for minor, limited, or temporary uses shall be first ap-
proved by the Authority Having Jurisdiction.
(C) Disposal systems shall be designed to utilize the most
porous or absorptive portions of the soil formation.
Where the groundwater level extends to within twelve
(12) feet (3,658 mm) or less of the ground surface or
where the upper soil is porous and the underlying stratum
is rock or impervious soil, a septic tank and disposal field
system shall be installed.
(D) Disposal systems shall be located outside of flood hazard
areas.
Exception: Where suitable sites outside of flood hazard
I areas are not available, disposal systems shall be permit-
I ted to be located in flood hazard areas on sites where the
effects of inundation under conditions of the design flood
are minimized.
(E) All private sewage disposal systems shall be so designed
that additional seepage pits or subsurface drain fields,
equivalent to not less than one-hundred (100) percent of
the required original system, shall be permitted to be in-
stalled where the original system cannot absorb all the
sewage. No division of the lot or erection of structures on
the lot shall be made if such division or structure impairs
the usefulness of the one-hundred (100) percent expan-
sion area.
(F) No property shall be improved in excess of its capacity
to properly absorb sewage effluent by the means pro-
vided in this code.
Exception: The Authority Having Jurisdiction shall be
permitted to, at its discretion, approve an alternate sys-
tem.
(G) No private sewage disposal system, or part thereof, shall
be located in any lot other than the lot that is the site of
the building or structure served by such private sewage
disposal system, nor shall any private sewage disposal
system or part thereof be located at any point having less
than the minimum distances indicated in Table K-1.
Nothing contained in this code shall be construed to
prohibit the use of all or part of an abutting lot to pro-
vide additional space for a private sewage disposal sys-
tem or part thereof when proper cause, transfer of
ownership, or change of boundary not in violation of
other requirements has been first established to the sat-
isfaction of the Authority Having Jurisdiction. The in-
strument recording such action shall constitute an
agreement with the Authority Having Jurisdiction, which
shall clearly state and show that the areas so joined or
used shall be maintained as a unit during the time they
are so used. Such agreement shall be recorded in the of-
fice of the County Recorder as part of the conditions of
ownership of said properties and shall be binding on all
heirs, successors, and assigns to such properties. A copy
of the instrument recording such proceedings shall be
filed with the Authority Having Jurisdiction.
(H) When there is insufficient lot area or improper soil con-
ditions for adequate sewage disposal for the building or
land use proposed, and the Authority Having Jurisdiction
so finds, no building permit shall be issued and no private
sewage disposal shall be permitted. Where space or soil
conditions are critical, no building permit shall be issued
until engineering data and test reports satisfactory to the
Authority Having Jurisdiction have been submitted and
approved.
(I) Nothing contained in this appendix shall be construed to
prevent the Authority Having Jurisdiction from requir-
ing compliance with additional requirements than those
contained herein, where such additional requirements are
essential to maintain a safe and sanitary condition.
(J) Alternate systems shall be permitted to be used only by
special permission of the Authority Having Jurisdiction
after being satisfied of their adequacy. This authorization
is based on extensive field and test data from conditions
similar to those at the proposed site, or require such ad-
ditional data as necessary to provide assurance that the
alternate system will produce continuous and long-range
results at the proposed site, not less than equivalent to
systems which are specifically authorized.
2010 CALIFORNIA PLUMBING CODE
457
PRIVATE SEWAGE DISPOSAL SYSTEMS
If demonstration systems are to be considered for instal-
lation, conditions for installation, maintenance, and monitor-
ing at each such site shall first be established by the Authority
Having Jurisdiction.
Approved aerobic systems shall be permitted to be sub-
stituted for conventional septic tanks provided the Authority
Having Jurisdiction is satisfied that such systems will pro-
duce results not less than equivalent to septic tanks, whether
their aeration systems are operating or not.
K 2.0 Capacity of Septic Tanks.
The liquid capacity of all septic tanks shall conform to Tables
K-2 and K-3 as determined by the number of bedrooms or
apartment units in dwelling occupancies and the estimated
waste/sewage design flow rate or the number of plumbing
fixture units as determined from Table 7-3 of this Code,
whichever is greater in other building occupancies. The ca-
pacity of any one (1) septic tank and its drainage system shall
be limited by the soil structure classification, as specified in
Table K-4.
(4) The minimum effective absorption area in any seepage
pit shall be calculated as the excavated sidewall area
below the inlet exclusive of any hardpan, rock, clay, or
other impervious formations. The minimum required
area of porous formation shall be provided in one (1) or
more seepage pits. No excavation shall extend within ten
(10) feet (3,048 mm) of the water table nor to a depth
where sewage contaminate underground water stratum
that is usable for domestic purposes.
Exception: In areas where the records or data indicate
that the groundwaters are grossly degraded, the ten (10)
foot (3,048 mm) separation requirement shall be permit-
ted to be reduced by the Authority Having Jurisdiction.
The applicant shall supply evidence of groundwater
depth to the satisfaction of the Authority Having Juris-
diction.
(5) Leaching chambers shall be sized on the bottom absorp-
tion area (nominal unit width) in square feet. The re-
quired area shall be calculated using Table K-4 with a
0.70 multiplier.
K 3.0 Area of Disposal Fields and Seepage Pits.
The minimum effective absorption area in disposal fields in
square feet (m^), and in seepage pits in square feet (m^) of
sidewall, shall be predicated on the required septic tank ca-
pacity in gallons (liters) and/or estimated waste/sewage flow
rate, whichever is greater, and shall conform to Table K-4 as
determined for the type of soil found in the excavation, and
shall be as follows:
( 1 ) When disposal fields are installed, a minimum of one-hun-
dred and fifty (150) square feet (14 m^) of trench bottom
shall be provided for each system exclusive of any hard
pan, rock, clay, or other impervious formations. Sidewall
area in excess of the required twelve (12) inches (305 mm)
and a maximum of thirty-six (36) inches (914 mm) below
the leach line shall be permitted to be added to the trench
bottom area when computing absorption areas.
(2) Where leaching beds are permitted in lieu of trenches, the
area of each such bed shall be not less than fifty (50) per-
cent greater than the tabular requirements for trenches.
Perimeter sidewall area in excess of the required twelve
(12) inches (305 mm) and a maximum of thirty-six (36)
inches (914 mm) below the leach line shall be permitted
to be added to the trench bottom area when computing
absorption areas.
(3) No excavation for a leach line or leach bed shall be lo-
cated within five (5) feet (1,524 mm) of the water table
nor to a depth where sewage may contaminate the under-
ground water stratum that is usable for domestic purposes.
Exception: In areas where the records or data indicate
that the groundwaters are grossly degraded, the five (5)
foot (1,524 mm) separation requirement shall be permit-
ted to be reduced by the Authority Having Jurisdiction.
The applicant shall supply evidence of groundwater
depth to the satisfaction of the Authority Having Juris-
diction,
K 4.0 Percolation Test.
(A) Wherever practicable, disposal field and seepage pit sizes
shall be computed from Table K-4. Seepage pit sizes shall
be computed by percolation tests, unless use of Table K-
4 is approved by the Authority Having Jurisdiction.
(B) In order to determine the absorption qualities of seepage
pits and of questionable soils other than those listed in
Table K-4, the proposed site shall be subjected to perco-
lation tests acceptable to the Authority Having Jurisdic-
tion.
(C) When a percolation test is required, no private disposal
system shall be permitted to serve a building if that test
shows the absorption capacity of the soil is less than 0.83
gallons per square foot (33.8 L/m^) or more than 5.12 gal-
lons per square foot (208 L/m^) of leaching area per 24
hours. If the percolation test shows an absorption rate
greater than 5.12 gallons per square foot (208 L/m^) per
24 hours, a private disposal system shall be permitted if
the site does not overlie groundwaters protected for drink-
ing water supplies, a minimum thickness of two (2) feet
(610 mm) of the native soil below the entire proposed sys-
tem is replaced by loamy sand, and the system design is
based on percolation tests made in the loamy sand.
K 5.0 Septic Tank Construction.
(A) Plans for all septic tanks shall be submitted to the Au-
thority Having Jurisdiction for approval. Such plans shall
show all dimensions, reinforcing, structural calculations,
and such other pertinent data as required.
(B) Septic tank design shall be such as to produce a clarified
effluent consistent with accepted standards and shall pro-
vide adequate space for sludge and scum accumulations.
(C) Septic tanks shall be constructed of solid durable mate-
rials not subject to excessive corrosion or decay and shall
be watertight.

shall not be paved over or covered by concrete or any
material that can reduce or inhibit any possible evapora-
tion of sewer effluent.
(J) When necessary on sloping ground to prevent excessive
line slope, leach lines or leach beds shall be stepped. The
lines between each horizontal section shall be made with
watertight joints and shall be designed so each horizon-
tal leaching trench or bed shall be utilized to the maxi-
mum capacity before the effluent shall pass to the next
lower leach line or bed. The lines between each horizon-
tal leaching section shall be made with approved water-
tight joints and installed on natural or unfilled ground.
K 7.0 Seepage Pits.
(A) The capacity of seepage pits shall be based on the quan-
tity of liquid waste discharging thereinto and on the char-
acter and porosity of the surrounding soil, and shall
conform to Section K 3.0 of this appendix.
(B) Multiple seepage pit installations shall be served through
an approved distribution box or be connected in series
by means of a watertight connection laid on undistrib-
uted or compacted soil; the outlet from the pit shall have

L 1.0 Scope.
L 1.1 The intent of this appendix is to provide clarification of
procedures for the design and approval of engineered plumb-
ing systems, alternate materials, and equipment not specifi-
cally covered in other parts of the code.
L 1.2 The provisions of this appendix apply to the design, in-
stallation, and inspection of an engineered plumbing system,
alternate material, and equipment.
L 1.3 The Authority Having Jurisdiction has the right to re-
quire descriptive details of an engineered plumbing system,
alternate material, or equipment including pertinent technical
data to be filed.
L 1.4 Components, materials, and equipment must conform
to standards and specifications listed in Table 14-1 of this
code and other national consensus standards applicable to
plumbing systems and materials.
L 1.5 Where such standards and specifications are not avail-
able, alternate materials and equipment must be approved per
the provisions of Section 301.2 of this code.
L 2.0 Engineered Plumbing Systems.
L 2.1 Definition. Engineered Plumbing System: A system de-
signed for a specific building project with drawings and spec-
ifications indicating plumbing materials to be installed, all as
prepared by a person registered or licensed to perform plumb-
ing design work.
L 2.2 Inspection and Installation. In other than one- and
two-family dwellings, the designer of the system is to pro-
vide periodic inspection of the installation on a schedule
found suitable to the Authority Having Jurisdiction. Prior to
the final approval, the designer must verify to the Authority
Having Jurisdiction that the installation is in compliance with
the approved plans, specifications, and data and such amend-
ments thereto. The designer must also certify to the Authority
Having Jurisdiction that the installation is in compliance with
the applicable engineered design criteria.
L 2.3 Owner Information. The designer of the system must
provide the building ovmer with information concerning the
system, considerations applicable for any subsequent modifi-
cations to the system, and maintenance requirements as appli-
cable.

tion.
L 4.0 Fixture Unit Values for Private or Private Use Bath- 1
room Groups.
L 4.1 Tables L-1 and L-2 reflect the fixture unit loads for the
fixtures in bathrooms as groups, rather than as individual fix-
tures. Such fixtures include water closets, lavatories, and
bathtubs or showers. The tables reflect diversity in the use of
fixtures within a bathroom and between multiple bathrooms.
L 4.2 The listed water supply fixture unit values in Table L-
1 reflect the load of entire bathroom groups on the cold-water
service. Individual hot and cold water branch piping to the
fixtures should be sized according to Chapter 6 and Appendix
A.
L 4.3 The listed drainage fixture unit values in Table L-2 reflect
the load of entire bathroom groups on the sanitary drainage sys-
tem. Where fixtures within bathrooms connect to different
branches of the drainage system, the fixture unit values for the
individual fixtures shall be used, as listed in Table 7-3 of this
code.

USEFUL TABLES
METRIC SYSTEM
(INTERNATIONAL SYSTEM OF UNITS - SI)
For the users of this code, we are including a short explanation and some conversion tables to aid in the conversion of our famil-
iar English units to the forthcoming SI units.
This is written with the code users in mind, and will detail only those measurements used in everyday work and calculations.
For the scientific units, we recommend the use of ANSI Z210.1, "Metric Practice Guide."
GENERAL COMMENTS
Our present system of measuring involves the three dimensions of force, length and time. The SI units involve mass, length, and
time. The change of force to mass has meaning in scientific and engineering work, but for practical use in ordinary construc-
tion, we will show kilogram to pounds conversion values, although an exact conversion would be pounds force divided by the
acceleration due to gravity to mass units.
In the same manner, the SI units for temperature expressed in Kelvins and based on absolute zero will be given as degrees
Celsius, which is the more familiar and practical Centigrade degrees.
The SI system measures angles in radians where there are 2 pi radians in a circle, but using a 1.5708 bend to change from a
vertical stack to a horizontal house drain is not as easy as calling out a 1/4 bend or an ell for water piping.
The foregoing notes are intended to show that in making conversions from one unit system to another, a little common sense
must be used and the degree of accuracy needed to do the job at hand.
The following tables are set up using this approach and using the preferred SI units.

When the plumbing industry, including plumbers, suppliers, and manufacturers, actually begins the metric conversion program,
it will undoubtedly follow the guidelines of committees selected from all phases of the construction industry as set up under the
American National Metric Council.
The final preferred units used will be those that apply to our industry and will be of the magnitude to simplify and ease job
calculations and avoid confrision and ambiguity.
The conversion looks complex and confusing, but when the metric system was first proposed in France, an attempt was made
to include a ten-hour day, a ten-day week, and ten months to the year, but cooler heads prevailed and our time still follows the
sun and seasons. Likewise, assigning new units or numbers to the quantities we must work with cannot change the basic hydraulic
principles that plumbers have worked with throughout history.
Information on conversion factors is provided by ANSI, the American National Metric Council, and the Division of Desig-
natronics. Inc.
