PREFACE
History
The State of Florida first mandated statewide building codes during the 1970s at the beginning of the modem construction boom.
The first law required all municipalities and counties to adopt and enforce one of the four state-recognized model codes known as
the "state minimum building codes." During the early 1990s a series of natural disasters, together with the increasing complexity of
building construction regulation in vastly changed markets, led to a comprehensive review of the state building code system. The
study revealed that building code adoption and enforcement was inconsistent throughout the state and those local codes thought to
be the strongest proved inadequate when tested by major hurricane events. The consequences of the building codes system failure
were devastation to lives and economies and a statewide property insurance crisis. The response was a reform of the state building
construction regulatory system that placed emphasis on uniformity and accountability.
The 1998 Florida Legislature amended Chapter 553, Florida Statutes (FS), Building Construction Standards, to create a single
state building code that is enforced by local governments. As of March 1 , 2002, the Florida Building Code, which is developed and
maintained by the Florida Building Commission, supersedes all local building codes. The Florida Building Code is updated every
three years and may be amended annually to incorporate interpretations and clarifications.
Scope
The Florida Building Code is based on national model building codes and national consensus standards which are amended
where necessary for Florida's specific needs. The code incorporates all building construction-related regulations for public and pri-
vate buildings in the State of Florida other than those specifically exempted by Section 553.73, Florida Statutes. It has been harmo-
nized with the Florida Fire Prevention Code, which is developed and maintained by the Department of Financial Services, Office
of the State Fire Marshal, to establish unified and consistent standards.
The base codes for the 2007 edition of the Florida Building Code include: the International Building Code®, 2006 edition; the
International Plumbing Code®, 2006 edition; the International Mechanical Code®, 2006 edition; the International Fuel Gas
Code®, 2006 edition; the International Residential Code®, 2006 edition; the International Existing Building Code®, 2006 edition;
the National Electrical Code, 2005 edition; the U. S. Department of Housing and Urban Development, Fair Housing Guidelines,
and; substantive criteria from the American Society of Heating, Refrigerating and Air-conditioning Engineers' (ASHRAE) Stan-
dard 90. 1-2004. State and local codes adopted and incorporated into the code include the Florida Energy Efficiency Code for Build-
ing Construction, the Florida Accessibility Code for Building Construction and special hurricane protection standards for the
high-velocity hurricane zone.
The code is composed of seven main volumes: the Florida Building Code, Building, which also includes Chapter 1 3 (energy effi-
ciency) and Chapter 1 1 (accessibility) as well as state regulations for licensed facilities; the Florida Building Code, Plumbing; the
Florida Building Code, Mechanical; the Florida Building Code, Fuel Gas; the Florida Existing Building Code; the Florida Build-
ing Code, Residential ; and the Florida Building Code, Test Protocols for High-Velocity Hurricane Zones. Chapter 27 of the
Florida Building Code, Building, adopts the National Electrical Code, NFPA 70, by reference. Chapter 33 of the Florida Building
Code, Residential adopts the National Electrical Code Requirements for One- and Two-Family Dwellings, NFPA 70A, by refer-
ence.
Under certain strictly defined conditions, local governments may amend requirements to be more stringent than the code. All lo-
cal amendments to the Florida Building Code must be adopted by local ordinance and reported to the Florida Building Commission
then posted on www.floridabuilding.org in Legislative format for a month before being enforced. Local amendments to the Florida
Building Code and the Florida Fire Prevention Code may be obtained from the Florida Building Commission web site, or from the
Florida Department of Community Affairs or the Florida Department of Financial Services, Office of the State Fire Marshal, re-
spectively.
Adoption and Maintenance
The Florida Building Code is adopted and updated with new editions triennially by the Florida Building Commission. It is
amended annually to incorporate interpretations, clarifications and to update standards. Minimum requirements for permitting,
plans review and inspections are established by the code, and local jurisdictions may adopt additional administrative requirements
that are more stringent. Local technical amendments are subject to strict criteria established by Section 553.73, F.S. They are subject
to commission review and adoption into the code or repeal when the code is updated triennially and are subject to appeal to the Com-
mission according to the procedures established by Section 553.73, F.S.
Ten Technical Advisory Committees (TACs), which are constituted consistent with American National Standards Institute
(ANSI) Guidelines, review proposed code changes and clarifications of the code and make recommendations to the Commission.
These TACs whose membership is constituted consistent with American National Standards Institute (ANSI) Guidelines include:
Accessibility; Joint Building Fire (a joint committee of the Commission and the State Fire Marshal); Building Structural; Code Ad-
2007 FLORIDA BUILDING CODE— PLUMBING Mi
ministration/ Enforcement; Electrical; Energy; Mechanical; Plumbing and Fuel Gas; Roofing; and Special Occupancy (state
agency construction and facility licensing regulations).
The Commission may only issue official code clarifications using procedures of Chapter 120, Florida Statutes. To obtain such a
clarification, a request for a Declaratory Statement (DEC) must be made to the Florida Building Commission in a manner that estab-
lishes a clear set of facts and circumstances and identifies the section of the code in question. Requests are analyzed by staff, re-
viewed by the appropriate Technical Advisory Committee, and sent to the Florida Building Commission for a first action. Draft
Declaratory Statements are subject to public comment and are finalized by the Commission at its next meeting. These interpreta-
tions establish precedents for situations having similar facts and circumstances and are typically incorporated into the code in the
next code amendment cycle. Non-binding opinions are available from the Building Officials Association of Florida's web site
(www.BOAF.net) and a Binding Opinion process is available online at www.floridabuilding.org.
Marginal Markings
Vertical lines in the margins within the body of the code indicate a change from the requirements of the base codes to the 2007
Florida Building Code effective October 1, 2008.
Sections deleted from the base code are designated "Reserved."

Note:
To adjust this table for other than a 5-inch design rain fall rate multiply the square footage on the table by 5 then divide by the local design rain fall rate.
Example:
For 4 inches of design rainfall rate, a 4-inch long scupper with a 1 inch head would accommodate 287 square feet. (230 x 5) -^4 = 287.
1107.3 Sizing of secondary drains. Secondary (emergency)
roof drain systems shall be sized in accordance with Section
11 06 based on the rainfall rate for which the primary system is
sized in Tables 1106.2, 1106.3 and 1106.6. Scuppers shall be
sized to prevent the depth of ponding water from exceeding
that for which the roof was designed as determined by Section
1101.7. Scuppers shall not have an opening dimension of less
than 4 inches (102 mm). The flow through the primary system
shall not be considered when sizing the secondary roof drain
system.
SECTION 1108
COMBINED SANITARY AND STORM SYSTEM
1108.1 Size of combined drains and sewers. The size of a
combination sanitary and storm drain or sewer shall be com-
puted in accordance with the method in Section 1106.3. The
fixture units shall be converted into an equivalent projected
roof or paved area. Where the total fixture load on the com-
bined drain is less than or equal to 256 fixture units, the equiva-
lent drainage area in horizontal projection shall be taken as
4,000 square feet (372 m^). Where the total fixture load
exceeds 256 fixture units, each additional fixture unit shall be
considered the equivalent of 15.6 square feet (1.5 m^) of drain-
age area. These values are based on a rainfall rate of 1 inch (25
mm) per hour.
SECTION 1109
VALUES FOR CONTINUOUS FLOW
1109.1 Equivalent roof area. Where there is a continuous or
semicontinuous discharge into the building storm drain or
building storm sewer, such as from a pump, ejector, air condi-
tioning plant or similar device, each gallon per minute (L/m) of
such discharge shall be computed as being equivalent to 96
square feet (9 m^) of roof area, based on a rainfall rate of 1 inch
(25.4 mm) per hour.
SECTION 1110
CONTROLLED FLOW ROOF DRAIN SYSTEMS
1110.1 General. The roof of a structure shall be designed for
the storage of water where the storm drainage system is engi-
neered for controlled flow. The controlled flow roof drain sys-
tem shall be an engineered system in accordance with this sec-
tion and the design, submittal, approval, inspection and testing
requirements of Secfion 105.4. The controlled flow system
shall be designed based on the required rainfall rate in accor-
dance with Secfion 1106.1.
1110.2 Control devices. The control devices shall be installed
so that the rate of discharge of water per minute shall not
exceed the values for continuous flow as indicated in Section
1109.1.
1110.3 Installation. Runoff control shall be by control
devices. Control devices shall be protected by strainers.
1110.4 Minimum number of roof drains. Not less than two
roof drains shall be installed in roof areas 10,000 square feet
(929 m^) or less and not less than four roof drains shall be
installed in roofs over 1 0,000 square feet (929 m^) in area.
SECTION 1111
SUBSOIL DRAINS
1111.1 Subsoil drains. Subsoil drains shall be open-jointed,
horizontally split or perforated pipe conforming to one of the
standards listed in Table 1 102.5. Such drains shall not be less
than 4 inches (1 02 mm) in diameter. Where the building is sub-
ject to backwater, the subsoil drain shall be protected by an
accessibly located backwater valve. Subsoil drains shall dis-
charge to a trapped area drain, sump, dry well or approved loca-
tion above ground. The subsoil sump shall not be required to
have either a gas-tight cover or a vent. The sump and pumping
system shall comply with Section 1 113.1.
SECTION 1112
BUILDING SUBDRAINS
1112.1 Building subdrains. Building subdrains located below
the public sewer level shall discharge into a sump or receiving
tank, the contents of which shall be automatically lifted and
discharged into the drainage system as required for building
sumps. The sump and pumping equipment shall comply with
Section 1113.1.

GRAY WATER RECYCLING SYSTEMS
Note: Section 301.3 of this code requires all plumbing fixtures that receive water or waste to discharge to the sanitary drainage sys-
tem of the structure. In order to allow for the utilization of a gray water system, Section 30 1 .3 should be revised to read as follows:
301.3 Connections to drainage system. All plumbing fix-
tures, drains, appurtenances and appliances used to receive or
discharge liquid wastes or sewage shall be directly connected
to the sanitary drainage system of the building or premises, in
accordance with the requirements of this code. This section
shall not be construed to prevent indirect waste systems
required by Chapter 8.
Exception: Bathtubs, showers, lavatories, clothes washers
and laundry trays shall not be required to discharge to the
sanitary drainage system where such fixtures discharge to
an approved gray water system for flushing of water closets
and urinals or for subsurface landscape irrigation.
SECTION C101

accordance with Section CI 02.3 shall be made between a gray
water recycling system and a potable water system.
C101.9 Waste water connections. Gray water recycling sys-
tems shall receive only the waste discharge of bathtubs, show-
ers, lavatories, clothes washers or laundry trays.
ClOl.lO Collection reservoir. Gray water shall be collected in
an approved reservoir constructed of durable, nonabsorbent
and corrosion-resistant materials. The reservoir shall be a
closed and gas-tight vessel. Access openings shall be provided
to allow inspection and cleaning of the reservoir interior.
ClOl.ll Filtration. Gray water entering the reservoir shall
pass through an approved filter such as a media, sand or
diatomaceous earth filter.

shall be identified as containing nonpotable water. Piping iden-
tification shall be in accordance with Section 608.8.
SECTION C1 03
SUBSURFACE LANDSCAPE IRRIGATION SYSTEMS
C103.1 Collection reservoir. Reservoirs shall be sized to limit
the retention time of gray water to a maximum of 24 hours.
C103.1.1 Identification. The reservoir shall be identified
as containing nonpotable water.
C103.2 Valves required. A check valve and a full-open valve
located on the discharge side of the check valve shall be
installed on the effluent pipe of the collection reservoir.
C103.3 Makeup water. Makeup water shall not be required
for subsurface landscape irrigation systems. Where makeup
water is provided, the installation shall be in accordance with
Section CI 02.3.
C103.4 Disinfection. Disinfection shall not be required for
gray water used for subsurface landscape irrigation systems.
C103.5 Coloring. Gray water used for subsurface landscape
irrigation systems shall not be required to be dyed.
C103.6 Estimating gray water discharge. The system shall
be sized in accordance with the gallons-per-day-per-occupant
number based on the type of fixtures connected to the gray
water system. The discharge shall be calculated by the follow-
ing equation:
A = Number of occupants:
Residential-Number of occupants shall be determined
by the actual number of occupants, but not less than two
occupants for one bedroom and one occupant for each
additional bedroom.
Commercial-Number of occupants shall be deter-
mined by the Florida Building Code, Building.
B = Estimated flow demands for each occupant:
Residential-25 gallons per day (94.6 Ipd) per occupant
for showers, bathtubs and lavatories and 1 5 gallons per
day (56.7 Ipd) per occupant for clothes washers or laun-
dry trays.
Commercial-Based on type of fixture or water use
records minus the discharge of fixtures other than those
discharging gray water.
C = Estimated gray water discharge based on the total num-
ber of occupants.
C103.7 Percolation tests. The permeability of the soil in the
proposed absorption system shall be determined by percolation
tests or permeability evaluation.
C103.7.1 Percolation tests and procedures. At least three
percolation tests in each system area shall be conducted.
The holes shall be spaced uniformly in relation to the bottom
depth of the proposed absorption system. More percolation
tests shall be made where necessary, depending on system
design.
C103.7.1.1 Percolation test hole. The test hole shall be
dug or bored. The test hole shall have vertical sides and a
horizontal dimension of 4 inches to 8 inches (102 mm to
203 mm). The bottom and sides of the hole shall be
scratched with a sharp-pointed instrument to expose the
natural soil. All loose material shall be removed from the
hole and the bottom shall be covered with 2 inches (5 1
mm) of gravel or coarse sand.
CI03.7.1.2 Test procedure, sandy soils. The hole shall
be filled with clear water to a minimum of 12 inches (305
mm) above the bottom of the hole for tests in sandy soils.
The time for this amount of water to seep away shall be
determined, and this procedure shall be repeated if the
water from the second filling of the hole seeps away in 1
minutes or less. The test shall proceed as follows: Water
shall be added to a point not more than 6 inches (152 mm)
above the gravel or coarse sand. Thereupon, from a fixed
reference point, water levels shall be measured at
10-minute intervals for a period of 1 hour. Where 6
inches (152 mm) of water seeps away in less than 1 min-
utes, a shorter interval between measurements shall be
used, but in no case shall the water depth exceed 6 inches
(152 mm). Where 6 inches (152 mm) of water seeps
away in less than 2 minutes, the test shall be stopped and
a rate of less than 3 minutes per inch (7.2 s/mm) shall be
reported. The final water level drop shall be used to cal-
culate the percolation rate. Soils not meeting the above
requirements shall be tested in accordance with Section
C103.7.1.3.
C103.7.1.3 Test procedure, other soils. The hole shall
be filled with clear water, and a minimum water depth of
12 inches (305 mm) shall be maintained above the bot-
tom of the hole for a 4-hour period by refilling whenever
necessary or by use of an automatic siphon. Water
remaining in the hole after 4 hours shall not be removed.
Thereafter, the soil shall be allowed to swell not less than
16 hours or more than 30 hours. Immediately after the
soil swelling period, the measurements for determining
the percolation rate shall be made as follows: Any soil
sloughed into the hole shall be removed and the water
level shall be adjusted to 6 inches (152 mm) above the
gravel or coarse sand. Thereupon, from a fixed reference
point, the water level shall be measured at 30-minute
intervals for a period of 4 hours, unless two successive
water level drops do not vary by more than 1 Vie inch
(1.59 mm). At least three water level drops shall be
observed and recorded. The hole shall be filled with clear
water to a point not more than 6 inches (1 52 mm) above
the gravel or coarse sand whenever it becomes nearly
empty. Adjustments of the water level shall not be made
during the three measurement periods except to the limits
of the last measured water level drop. When the first 6
inches (152 mm) of water seeps away in less than 30 min-
utes, the time interval between measurements shall be 10
minutes and the test run for 1 hour. The water depth shall
not exceed 5 inches (127 mm) at any time during the
measurement period. The drop that occurs during the
final measurement period shall be used in calculating the
percolation rate.

C103.7.1.4 Mechanical test equipment. Mechanical
percolation test equipment shall be of an approved type.
C103.7.2 Permeability evaluation. Soil shall be evaluated
for estimated percolation based on structure and texture in
accordance with accepted soil evaluation practices. Borings
shall be made in accordance with Section CI 03.7. 1 for eval-
uating the soil.
CI 03.8 Subsurface landscape irrigation site location. The
surface grade of all soil absorption systems shall be located at a
point lower than the surface grade of any water well or reser-
voir on the same or adjoining property. Where this is not possi-
ble, the site shall be located so surface water drainage from the
site is not directed toward a well or reservoir. The soil absorp-
tion system shall be located with a minimum horizontal dis-
tance between various elements as indicated in Table C 103.8.
Private sewage disposal systems in compacted areas, such as
parking lots and driveways, are prohibited. Surface water shall
be diverted away from any soil absorption site on the same or
neighboring lots.

excavations shall be a minimum of 1 foot (304 mm) to a
maximum of 5 feet (1524 mm) wide. Trench excavations
shall be spaced a minimum of 2 feet (610 mm) apart. The
soil absorption area of a seepage trench shall be computed
by using the bottom of the trench area (width) multiplied by
the length of pipe. Individual seepage trenches shall be a
maximum of 100 feet (30 480 mm) in developed length.
C103.9.3 Seepage bed excavations. Seepage bed excava-
tions shall be a minimum of 5 feet ( 1 524 mm) wide and have
more than one distribution pipe. The absorption area of a
seepage bed shall be computed by using the bottom of the

uniformly spaced a maximum of 5 feet (1524 nmi) and a
minimum of 3 feet (9 1 4 mm) apart, and a maximum of 3 feet
(914 mm) and a minimum of 1 foot (3 05 mm) from the side-
wall or headwall.
CI 03.9.4 Excavation and construction. The bottom of a
trench or bed excavation shall be level. Seepage trenches or
beds shall not be excavated where the soil is so wet that such
material rolled between the hands forms a soil wire. All
smeared or compacted soil surfaces in the sidewalls or bot-
tom of seepage trench or bed excavations shall be scarified
to the depth of smearing or compaction and the loose mate-
rial removed. Where rain falls on an open excavation, the
soil shall be left until sufficiently dry so a soil wire will not
form when soil from the excavation bottom is rolled
between the hands. The bottom area shall then be scarified
and loose material removed.
CI 03.9.5 Aggregate and backfill. A minimum of 6 inches
of aggregate ranging in size from Vi to 2 'A inches (12.7 mm
to 64 mm) shall be laid into the trench below the distribution
piping elevation. The aggregate shall be evenly distributed a
minimum of 2 inches (51 mm) over the top of the distribu-
tion pipe. The aggregate shall be covered with approved

SIZING OF WATER PIPING SYSTEM
SECTION E1 01
GENERAL
ElOl.l Scope.
ElOl.l.l This appendix outlines two procedures for sizing
a water piping system (see Sections El 03.3 and E201.1).
The design procedures are based on the minimum static
pressure available from the supply source, the head charges
in the system caused by friction and elevation, and the rates
of flow necessary for operation of various fixtures.
ElOl.1.2 Because of the variable conditions encountered in
hydraulic design, it is impractical to specify definite and
detailed rules for sizing of the water piping system. Accord-
ingly, other sizing or design methods conforming to good
engineering practice standards are acceptable alternatives
to those presented herein.
SECTION E102
INFORMATION REQUIRED
ElOl.l Preliminary. Obtain the necessary information
regarding the minimum daily static service pressure in the area
where the building is to be located. If the building supply is to
be metered, obtain information regarding friction loss relative
to the rate of flow for meters in the range of sizes likely to be
used. Friction loss data can be obtained from most manufactur-
ers of water meters.
E102.2 Demand load.
E102.2.1 Estimate the supply demand of the building main
and the principal branches and risers of the system by total-
ing the corresponding demand from the applicable part of
Table E103.3(3).
E102.2.2 Estimate continuous supply demands in gallons
per minute (L/m) for lawn sprinklers, air conditioners, etc.,
and add the sum to the total demand for fixtures. The result
is the estimated supply demand for the building supply.
SECTION El 03
SELECTION OF PIPE SIZE
E103.1 General. Decide from Table 604.3 what is the desir-
able minimum residual pressure that should be maintained at
the highest fixture in the supply system. If the highest group of
fixtures contains flush valves, the pressure for the group should
not be less than 15 pounds per square inch (psi) (103.4 kPa)
flowing. For flush tank supplies, the available pressure should
not be less than 8 psi (55.2 kPa) flowing, except blowout action
fixtures must not be less than 25 psi (172.4 kPa) flowing.
E103.2 Pipe sizing.
E103.2.1 Pipe sizes can be selected according to the follow-
ing procedure or by other design methods conforming to
acceptable engineering practice and approved by the admin-
istrative authority. The sizes selected must not be less than
the minimum required by this code.
E103.2.2 Water pipe sizing procedures are based on a sys-
tem of pressure requirements and losses, the sum of which
must not exceed the minimum pressure available at the sup-
ply source. These pressures are as follows:
1 . Pressure required at fixture to produce required flow.
See Sections 604.3 and 604.5.
2. Static pressure loss or gain (due to head) is computed
at 0.433 psi per foot (9.8 kPa/m) of elevation change.
Example: Assume that the highest fixture supply
outlet is 20 feet (6096 mm) above or below the
supply source. This produces a static pressure dif-
ferential of 20 feet by 0.433 psi/foot (2096 mm by
9.8 kPa/m) and an 8.66 psi (59.8 kPa) loss.
3. Loss through water meter. The friction or pressure
loss can be obtained from meter manufacturers.
4. Loss through taps in water main.
5. Losses through special devices such as filters, soften-
ers, backflow prevention devices and pressure regula-
tors. These values must be obtained from the
manufacturers.
6. Loss through valves and fittings. Losses for these
items are calculated by converting to equivalent
length of piping and adding to the total pipe length.
7. Loss due to pipe friction can be calculated when the
pipe size, the pipe length and the flow through the
pipe are known. With these three items, the friction
loss can be determined. For piping flow charts not
included, use manufacturers' tables and velocity rec-
ommendations.
Note: For the purposes of all examples, the following
metric conversions are applicable:
1 cubic foot per minute = 0.4719 L/s
1 square foot = 0.0929 m^
1 degree = 0.0175 rad
1 pound per square inch = 6.895 kPa
1 inch = 25.4 mm
1 foot = 304.8 mm
1 gallon per minute = 3.785 L/m
E103.3 Segmented loss method. The size of water service
mains, branch mains and risers by the segmented loss method,
must be determined according to water supply demand [gpm
(L/m)], available water pressure [psi (kPa)] and friction loss
caused by the water meter and developed length of pipe [feet
(m)], including equivalent length of fittings. This design proce-
dure is based on the following parameters:
• Calculates the friction loss through each length of the pipe.
2007 FLORIDA BUILDING CODE— PLUMBING
E.1
APPENDIX E
• Based on a system of pressure losses, the sum of which
must not exceed the minimum pressure available at the
street main or other source of supply.
• Pipe sizing based on estimated peak demand, total pressure
losses caused by difference in elevation, equipment, devel-
oped length and pressure required at most remote fixture,
loss through taps in water main, losses through fittings, fil-
ters, backflow prevention devices, valves and pipe friction.
Because of the variable conditions encountered in hydraulic
design, it is impractical to specify definite and detailed rules for
sizing of the water piping system. Current sizing methods do
not address the differences in the probability of use and flow
characteristics of fixtures between types of occupancies. Creat-
ing an exact model of predicting the demand for a building is
impossible and final studies assessing the impact of water con-
servation on demand are not yet complete. The following steps
are necessary for the segmented loss method.
1 . Preliminary. Obtain the necessary information regard-
ing the minimum daily static service pressure in the area
where the building is to be located. If the building supply
is to be metered, obtain information regarding friction
loss relative to the rate of flow for meters in the range of
sizes to be used. Friction loss data can be obtained from
manufacturers of water meters. It is essential that enough
pressure be available to overcome all system losses
caused by friction and elevation so that plumbing fix-
tures operate properly. Section 604.6 requires the water
distribution system to be designed for the minimum pres-
sure available taking into consideration pressure fluctua-
tions. The lowest pressure must be selected to guarantee
a continuous, adequate supply of water. The lowest pres-
sure in the public main usually occurs in the summer
because of lawn sprinkling and supplying water for
air-conditioning cooling towers. Future demands placed
on the public main as a result of large growth or expan-
sion should also be considered. The available pressure
will decrease as additional loads are placed on the public
system.
2. Demand load. Estimate the supply demand of the build-
ing main and the principal branches and risers of the sys-
tem by totaling the corresponding demand from the
applicable part of Table El 03.3(3). When estimating
peak demand sizing methods typically use water supply
fixture units (w.s.f.u.)[see Table E103.3(2)]. This
numerical factor measures the load-producing effect of a
single plumbing fixture of a given kind. The use of such
fixture units can be applied to a single basic probability
curve (or table), found in the various sizing methods
[Table E103.3(3)]. The fixture units are then converted
into gallons per minute (L/m) flow rate for estimating
demand.
2.1. Estimate continuous supply demand in gallons
per minute (L/m) for lawn sprinklers, air condi-
tioners, etc., and add the sum to the total demand
for fixtures. The result is the estimated supply
demand for the building supply. Fixture units
cannot be applied to constant use fixtures such as
hose bibbs, lawn sprinklers and air conditioners.
These types of fixtures must be assigned the gal-
lon per minute (L/m) value.
3. Selection of pipe size. This water pipe sizing procedure
is based on a system of pressure requirements and losses,
the sum of which must not exceed the minimum pressure
available at the supply source. These pressures are as fol-
lows:
3.1. Pressure required at the fixture to produce
required flow. See Section 604.3 and Section
604.5.
3.2. Static pressure loss or gain (because of head) is
computed at 0.433 psi per foot (9.8 kPa/m) of ele-
vation change.
3.3. Loss through a water meter. The fi-iction or pres-
sure loss can be obtained from the manufacturer.
3.4. Loss through taps in water main [see Table
E103.3(4)].
3.5. Losses through special devices such as filters,
softeners, backflow prevention devices and pres-
sure regulators. These values must be obtained
fi-om the manufacturers.
3.6. Loss through valves and fittings [see Tables
El 03. 3 (5) and El 03. 3 (6)]. Losses for these items
are calculated by converting to equivalent length
of piping and adding to the total pipe length.
3.7. Loss caused by pipe friction can be calculated
when the pipe size, the pipe length and the flow
through the pipe are known. With these three
items, the friction loss can be determined using
Figures El 03. 3(2) through El 03. 3(7). When
using charts, use pipe inside diameters. For pip-
ing flow charts not included, use manufacturers'
tables and velocity recommendations. Before
attempting to size any water supply system, it is
necessary to gather preliminary information
which includes available pressure, piping mate-
rial, select design velocity, elevation differences
and developed length to most remote fixture. The
water supply system is divided into sections at
major changes in elevation or where branches
lead to fixture groups. The peak demand must be
determined in each part of the hot and cold water
supply system which includes the corresponding
water supply fixture unit and conversion to gal-
lons per minute (L/m) flow rate to be expected
through each section. Sizing methods require the
determination of the "most hydraulically
remote" fixture to compute the pressure loss
caused by pipe and fittings. The hydraulically
remote fixture represents the most downstream
fixture along the circuit of piping requiring the
most available pressure to operate properly. Con-
sideration must be given to all pressure demands
and losses, such as friction caused by pipe, fit-
tings and equipment, elevation and the residual
pressure required by Table 604.3. The two most
common and frequent complaints about the
E.2
2007 FLORIDA BUILDING CODE— PLUMBING
APPENDIX E
water supply system operation are lack of ade-
quate pressure and noise.
Problem: What size Type L copper water pipe, service and dis-
tribution will be required to serve a two-story factory building
having on each floor, back-to-back, two toilet rooms each
equipped with hot and cold water? The highest fixture is 2 1 feet
(640 1 mm) above the street main, which is tapped with a 2-inch
(5 1 mm) corporation cock at which point the minimum pres-
sure is 55 psi (379.2 kPa). In the building basement, a 2-inch
(51 mm) meter with a maximum pressure drop of 1 1 psi (75.8
kPa) and 3-inch (76 mm) reduced pressure principle backflow
preventer with a maximum pressure drop of 9 psi (62 1 kPa) are
to be installed. The system is shown by Figure E103.3(l). Tobe
determined are the pipe sizes for the service main and the cold
and hot water distribution pipes.
Solution: A tabular arrangement such as shown in Table
El 03.3(1) should first be constructed. The steps to be fol-
lowed are indicated by the tabular arrangement itself as they
are in sequence, columns 1 through 10 and lines A through
L.
Stepl
Columns 1 and 2: Divide the system into sections breaking
at major changes in elevation or where branches lead to fix-
ture groups. After point B [see Figure E103.3(l)], separate
consideration will be given to the hot and cold water piping.
Enter the sections to be considered in the service and cold
water piping in Column 1 of the tabular arrangement. Col-
umn 1 of Table E103.3(l) provides a line-by-line recom-
mended tabular arrangement for use in solving pipe sizing.
The objective in designing the water supply system is to
ensure an adequate water supply and pressure to all fixtures
and equipment. Column 2 provides the pounds per square
inch (psi) to be considered separately from the minimum
pressure available at the main. Losses to take into consider-
ation are the following: the differences in elevations
between the water supply source and the highest water sup-
ply outlet, meter pressure losses, the tap in main loss, special
fixture devices such as water softeners and backflow pre-
vention devices and the pressure required at the most remote
fixture outlet. The difference in elevation can result in an
increase or decrease in available pressure at the main.
Where the water supply outlet is located above the source,
this results in a loss in the available pressure and is sub-
tracted from the pressure at the water source. Where the
highest water supply outlet is located below the water sup-
ply source, there will be an increase in pressure that is added
to the available pressure of the water source.
Column 3: According to Table El 03.3(3), determine the
gpm (L/m) of flow to be expected in each section of the sys-
tem. These flows range from 28.6 to 108 gpm. Load values
for fixtures must be determined as water supply fixture units
and then converted to a gallon-per-minute (gpm) rating to
determine peak demand. When calculating peak demands,
the water supply fixture units are added and then converted
to the gallon-per-minute rating. For continuous flow fix-
tures such as hose bibbs and lawn sprinkler systems, add the
gallon-per-minute demand to the intermittent demand of
fixtures. For example, a total of 120 water supply fixture
units is converted to a demand of 48 gallons per minute.
Two hose bibbs x 5 gpm demand =10 gpm. Total gpm rating
== 48.0 gpm + 10 gpm = 58.0 gpm demand.
Step 2
Line A: Enter the minimum pressure available at the main
source of supply in Column 2. This is 55 psi (379.2 kPa).
The local water authorities generally keep records of pres-
sures at different times of day and year. The available pres-
sure can also be checked from nearby buildings or from fire
department hydrant checks.
Line B: Determine from Table 604.3 the highest pressure
required for the fixtures on the system, which is 15 psi
(103.4 kPa), to operate a flushometer valve. The most
remote fixture outlet is necessary to compute the pressure
loss caused by pipe and fittings, and represents the most
downstream fixture along the circuit of piping requiring the
available pressure to operate properly as indicated by Table
604.3.
Line C: Determine the pressure loss for the meter size given
or assumed. The total water flow from the main through the
service as determined in Step 1 will serve to aid in the meter
selected. There are three common types of water meters; the
pressure losses are determined by the American Water
Works Association Standards for displacement type, com-
pound type and turbine type. The maximum pressure loss of
such devices takes into consideration the meter size, safe
operating capacity (gpm) and maximum rates for continu-
ous operations (gpm). Typically, equipment imparts greater
pressure losses than piping.
Line D: Select fi"om Table El 03. 3(4) and enter the pressure
loss for the tap size given or assumed. The loss of pressure
through taps and tees in pounds per square inch (psi) are
based on the total gallon-per-minute flow rate and size of the
tap.
Line E: Determine the difference in elevation between the
main and source of supply and the highest fixture on the sys-
tem. Multiply this figure, expressed in feet, by 0.43 psi (2.9
kPa). Enter the resulting psi loss on Line E. The difference
in elevation between the water supply source and the high-
est water supply outlet has a significant impact on the sizing
of the water supply system. The difference in elevation usu-
ally results in a loss in the available pressure because the
water supply outlet is generally located above the water sup-
ply source. The loss is caused by the pressure required to lift
the water to the outlet. The pressure loss is subtracted from
the pressure at the water source. Where the highest water
supply outlet is located below the water source, there will be
an increase in pressure which is added to the available pres-
sure of the water source.
Lines F, G and H: The pressure losses through filters,
backflow prevention devices or other special fixtures must
be obtained fi-om the manufacturer or estimated and entered
on these lines. Equipment such as backflow prevention
devices, check valves, water softeners, instantaneous or
tankless water heaters, filters and strainers can impart a
much greater pressure loss than the piping. The pressure
losses can range from 8 psi to 30 psi.

APPENDIX E
Step 3
Line I: The sum of the pressure requirements and losses that
affect the overall system (Lines B through H) is entered on
this line. Summarizing the steps, all of the system losses are
subtracted from the minimum water pressure. The remain-
der is the pressure available for friction, defined as the
energy available to push the water through the pipes to each
fixture. This force can be used as an average pressure loss,
as long as the pressure available for friction is not exceeded.
Saving a certain amount for available water supply pres-
sures as an area incurs growth, or because of aging of the
pipe or equipment added to the system is recommended.
Step 4
Line J: Subtract Line I from Line A. This gives the pressure
that remains available from overcoming friction losses in
the system. This figure is a guide to the pipe size that is cho-
sen for each section, incorporating the total friction losses to
the most remote outlet (measured length is called developed
length).
Exception: When the main is above the highest fixture,
the resulting psi must be considered a pressure gain
(static head gain) and omitted from the sums of Lines B
through H and added to Line J.
The maximum friction head loss that can be tolerated in
the system during peak demand is the difference between
the static pressure at the highest and most remote outlet at
no-flow conditions and the minimum flow pressure
required at that outlet. If the losses are within the required
limits, then every run of pipe will also be within the required
friction head loss. Static pressure loss is the most remote
outlet in feet x 0.433 = loss in psi caused by elevation differ-
ences.
Steps
Column 4: Enter the length of each section fi"om the main to
the most remote outlet (at Point E). Divide the water supply
system into sections breaking at major changes in elevation
or where branches lead to fixture groups.
Step 6
Column 5: When selecting a trial pipe size, the length from
the water service or meter to the most remote fixture outlet
must be measured to determine the developed length. How-
ever, in systems having a flush valve or temperature con-
trolled shower at the top most floors the developed length
would be from the water meter to the most remote flush
valve on the system. A rule of thumb is that size will become
progressively smaller as the system extends farther from the
main source of supply. Trial pipe size may be arrived at by
the following formula:
Line J: (Pressure available to overcome pipe friction) x
100/equivalent length of run total developed length to most
remote fixture x percentage factor of 1 .5 (note: a percentage
factor is used only as an estimate for friction losses imposed
for fittings for initial trial pipe size) = psi (average pressure
drops per 100 feet of pipe).
For trial pipe size see Figure E 103.3(3) (Type L copper)
based on 2.77 psi and a 108 gpm = 2 V2 inches. To determine
the equivalent length of run to the most remote outlet, the
developed length is determined and added to the friction
losses for fittings and valves. The developed lengths of the
designated pipe sections are as follows:
A - B 54 ft
B-C 8ft
C-D 13 ft
D-E 150 ft
Total developed length = 225 ft
The equivalent length of the friction loss in fittings and
valves must be added to the developed length (most remote
outlet). Where the size of fittings and valves is not known,
the added friction loss should be approximated. A general
rule that has been used is to add 50 percent of the developed
length to allow for fittings and valves. For example, the
equivalent length of run equals the developed length of run
(225 ft X 1 .5 = 338 ft). The total equivalent length of run for
determining a trial pipe size is 338 feet.
Example: 9.36 (pressure available to overcome pipe
friction) x 1 00/ 338 (equivalent length of run = 225 x 1 .5)
= 2.77 psi (average pressure drop per 100 feet of pipe).
Step?
Column 6: Select from Table E103.3(6) the equivalent
lengths for the trial pipe size of fittings and valves on each
pipe section. Enter the sum for each section in Column 6.
(The number of fittings to be used in this example must be
an estimate.) The equivalent length of piping is the devel-
oped length plus the equivalent lengths of pipe correspond-
ing to friction head losses for fittings and valves. Where the
size of fittings and valves is not known, the added friction
head losses must be approximated. An estimate for this
example is found in Table E.l.
Steps
Column 7: Add the figures from Column 4 and Column 6, and
enter in Column 7. Express the sum in hundreds of feet.

Column 8: Select from Figure El 03.3(3) the friction loss
per 100 feet (30 480 mm) of pipe for the gallon-per-minute
flow in a section (Column 3) and trial pipe size (Column 5).
Maximum friction head loss per 100 feet is determined on
the basis of total pressure available for friction head loss and
the longest equivalent length of run. The selection is based
on the gallon-per-minute demand, the uniform friction head
loss, and the maximum design velocity. Where the size indi-
cated by hydraulic table indicates a velocity in excess of the
selected velocity, a size must be selected which produces the
required velocity.
Step 10
Column 9: Multiply the figures in Columns 7 and 8 for each
section and enter in Column 9.
Total friction loss is determined by multiplying the fric-
tion loss per 100 feet (30 480 mm) for each pipe section in
the total developed length by the pressure loss in fittings
expressed as equivalent length in feet. Note: Section C-F
should be considered in the total pipe friction losses only if
greater loss occurs in Section C-F than in pipe section D-E.
Section C-F is not considered in the total developed length.
Total friction loss in equivalent length is determined in
Table E.2.
Step 11
Line K: Enter the sum of the values in Column 9. The value
is the total friction loss in equivalent length for each desig-
nated pipe section.
Step 12
Line L: Subtract Line J from Line K and enter in Column
10.
The result should always be a positive or plus figure. If it
is not, repeat the operation using Columns 5, 6, 8 and 9 until
a balance or near balance is obtained. If the difference
between Lines J and K is a high positive number, it is an
indication that the pipe sizes are too large and should be
reduced, thus saving materials. In such a case, the opera-
tions using Columns 5, 6, 8 and 9 should again be repeated.
The total friction losses are determined and subtracted
from the pressure available to overcome pipe friction for
trial pipe size. This number is critical as it provides a guide
to whether the pipe size selected is too large and the process
should be repeated to obtain an economically designed sys-
tem.
Answer: The final figures entered in Column 5 become the
design pipe size for the respective sections. Repeating this
operation a second time using the same sketch but consider-
ing the demand for hot water, it is possible to size the hot
water distribution piping. This has been worked up as a part
of the overall problem in the tabular arrangement used for
sizing the service and water distribution piping. Note that
consideration must be given to the pressure losses from the
street main to the water heater (Section A-B) in determining
the hot water pipe sizes.

APPENDIX E
SECTION E201
SELECTION OF PIPE SIZE
E 201.1 Size of water-service mains, brancli mains and ris-
ers. The minimum size water service pipe shall be ^U inch (19.1
mm). The size of water service mains, branch mains and risers
shall be determined according to water supply demand [gpm
(L/m)], available water pressure [psi (kPa)] and friction loss
due to the water meter and developed length of pipe [feet (m)],
including equivalent length of fittings. The size of each water
distribution system shall be determined according to the proce-
dure outlined in this section or by other design methods con-
forming to acceptable engineering practice and approved by
the code official:
1. Supply load in the building water-distribution system
shall be determined by total load on the pipe being sized,
in terms of water-supply fixture units (w.s.f u.), as
shown in Table E 1 03 .3(2). For fixtures not listed, choose
a w.s.f u. value of a fixture with similar flow characteris-
tics.
2. Obtain the minimum daily static service pressure [psi
(kPa)] available (as determined by the local water
authority) at the water meter or other source of supply at
the installation location. Adjust this minimum daily
static pressure [psi (kPa)] for the following conditions:
2.1. Determine the difference in elevation between
the source of supply and the highest water supply
outlet. Where the highest water supply outlet is
located above the source of supply, deduct 0.5 psi
(3.4 kPa) for each foot (0.3 m) of difference in
elevation. Where the highest water supply outlet
is located below the source of supply, add 0.5 psi
(3.4 kPa) for each foot (0.3 m) of difference in
elevation.
2.2. Where a water pressure reducing valve is
installed in the water distribution system, the
minimum daily static water pressure available is
80 percent of the minimum daily static water
pressure at the source of supply or the set pres-
sure downstream of the pressure reducing valve,
whichever is smaller.
2.3. Deduct all pressure losses due to special equip-
ment such as a backflow preventer, water filter
and water softener. Pressure loss data for each
piece of equipment shall be obtained through the
manufacturer of such devices.
2.4. Deduct the pressure in excess of 8 psi (55 kPa)
due to installation of the special plumbing fix-
ture, such as temperature controlled shower and
flushometer tank water closet.
Using the resulting minimum available pres-
sure, find the corresponding pressure range in
Table E20 1.1.
3. The maximum developed length for water piping is the
actual length of pipe between the source of supply and
the most remote fixture, including either hot (through the
water heater) or cold water branches multiplied by a
factor of 1 .2 to compensate for pressure loss through fit-
tings.
Select the appropriate column in Table E20 1 . 1 equal
to or greater than the calculated maximum developed
length.
4. To determine the size of water service pipe, meter and
main distribution pipe to the building using the appropri-
ate table, follow down the selected "maximum devel-
oped length" column to a fixture unit equal to, or greater
than the total installation demand calculated by using the
"combined" water supply fixture unit column of Table
E 1 03 .3(2). Read the water service pipe and meter sizes in
the first left-hand column and the main distribution pipe
to the building in the second left-hand column on the
same row.
5. To determine the size of each water distribution pipe,
start at the most remote outlet on each branch (either hot
or cold branch) and, working back toward the main dis-
tribution pipe to the building, add up the water supply
fixture unit demand passing through each segment of the
distribution system using the related hot or cold column
of Table El 03.3(2). Knowing demand, the size of each
segment shall be read from the second left-hand column
of the same table and maximum developed length col-
umn selected in Steps 1 and 2, under the same or next
smaller size meter row. In no case does the size of any
branch or main need to be larger that the size of the main
distribution pipe to the building established in Step 4.

PART II - DESIGN CRITERIA
A. Design DeOned. Within the scope of this code, irrigation
system design is defined as the science and art of properly
selecting and applying all components within the system.
B. Water Supply.
1 . The water source shall be adequate from the standpoint
of volume, flow rate, pressure, and quality to meet the ir-
rigation requirements of the area to be irrigated, as well
as other demands, if any, both at the time the system is
designed and for the expected life of the system.
2. If the water source is effluent, it shall meet the advanced
waste treatment standard as set forth in Florida Statute
§403.086(4) as well as any other standard as set forth by
the controlling governmental agency.
E. Sprinkler/Emitter Spacing and Selection. Sprin-
kler/Emitter spacing will be determined considering the irriga-
tion requirements, hydraulic characteristics of the soil and
device, and water quality with its effect on plant growth, side-
walks, buildings, and public access areas. When using square
spacing sprinklers should not be spaced farther apart than 55
percent of their manufacturer-specified diameters of coverage
for prevailing wind speeds of 5 miles per hour (mph) or less.
Spacing should not exceed 50 percent of sprinkler diameters of
coverage for wind speeds of 5 to 10 mph, and 45 percent for
prevailing wind speeds greater than 10 mph. When using trian-
gular spacing the above overlap percentages can be reduced by
five percent. Water conservation, will be emphasized by mini-
mizing irrigation of non- vegetated areas. Micro- irrigation sys-
tems should be designed using the Emission Uniformity
concept. Space micro-irrigation emitters to wet 100 percent of
the root zone in turf areas and 50 percent of the root zone for
shrubs and trees.
F. Pipelines. Pipelines will be sized to limit pressure variations
so that the working pressure at all points in the irrigation sys-
tem will be in the range required for uniform water application.
Velocities will be kept to 5 feet (1524 mm) per second.
G. Wells.
C. Application Uniformity. Irrigation application uniformity
describes how evenly water is distributed within an irrigation
zone. Irrigation system uniformity is the uniformity coeffi-
cient. Use application rates which avoid runoff and permit uni-
form water infiltration into the soil. Land slope, soil hydraulic
properties, vegetative ground cover, and prevailing winds will
be considered when application rates are specified. Sprinkler
irrigation systems should be designed with the appropriate uni-
formity for the type of plant being grown and the type of soil
found in that area. The general watering of different types of
plants as one group without regard to their individual water re-
quirements is to be avoided if at all possible. Different types of
sprinklers with different application rates, i.e., spray heads vs.
rotor heads, shall not be combined on the same zone or circuit.
1 . Well diameters and depths are to be sized to correspond ,
to the irrigation system demand. Refer to SCS Code
FL-642 and local water management district regulations
2. Well location and depth shall be in comphance with ap-
plicable state, water management district and local
codes.
H. Pumps.
1 . Pump and motor combinations shall be capable of satis-
fying the total system demand without invading the ser-
vice factor of the motor except during start-up and
between zones.
D. System Zoning. The irrigation system should be divided
into zones based on consideration of the following:
1 . Available flow rate.
2. Cultural use of the area.
3. Type of vegetation irrigated, i.e., turf, shrubs, native
plants, etc.
2. Pumps shall be positioned with respect to the water sur-
face in order to ensure that the net positive suction head
required (NPSHr) for proper pump operation is
achieved.
3. The pumping system shall be protected against the ef-
fects of the interruption of water flow.
I. Control Valves.
4. Type of sprinkler, i.e., sprinklers with matching precipi-
tation rates.
5. Soil characteristics.
1 . Control valve size shall be based on the flow rate through
the valve. Friction loss through the valve an approved air
gap separation or a reduced pressure should not exceed
10 percent of the static mainline head.
F.6
2007 FLORIDA BUILDING CODE— PLUMBING
APPENDIX F
2. Control systems using hydraulic communication be-
tween controller and valve(s) shall comply with the man-
ufacturers recommendations for maximum distance
between controller and valve both horizontally and verti-
cally (elevation change).
3. The size of the electrical control wire shall be in accor-
dance with the valve manufacturer's specifications
based on the solenoid in-rush amperage and the circuit
length, considering the number of solenoids operating on
the circuit. Minimum of # 14 AWG single strand control
wire shall be used on all systems, except individual, sin-
gle lot residential systems.
4. Locate manually operated control valves so that they can
be operated without wetting the operator.
J. Automatic Irrigation Controller. Automatic irrigation
controllers must be UL approved and have an adequate number
of stations and power output per station to accommodate the ir-
rigation system design. The controller shall be capable of in-
corporating a rain shut off device to override the irrigation
cycle when adequate rainfall has occurred, as required by
Florida Statutes, Section 373.62.
K. Chemical Injection.
1 . Chemical injection systems for the injection of fertilizer,
pesticides, rust inhibitors, or any other injected
sub-stance will be located and sized according to the
manufacturers' recommendations.
2. Injection systems will be located downstream of the ap-
plicable backflow prevention devices as required by
Florida Statutes, Section 487.021 and 487.055; the En-
vironmental Protection Agency (EPA); Pesticide Regu-
lation Notice 87-1; or other applicable codes.
3. If an irrigation water supply is also used for human con-
sumption, an air gap separation or an approved reduced
pressure principal backflow prevention device is re-
quired.
L. Backflow Prevention Methods. Provide backflow preven-
tion assemblies at all cross connections with all water supplies
in accordance with county, municipal,or other applicable
codes to determine acceptable backflow prevention assembly
types and installation procedures for a given application. In the
event of conflicting regulation provide the assembly type
which gives the highest degree of protection.
1. Irrigation systems into which chemicals are injected
shall conform to Florida state law (Florida Statutes
487.021 and 487.055) and Environmental Protection
Agency Pesticide Regulation Notice 87-1, which re-
quires backflow prevention regulations to be printed on
the chemical label.
2. For municipal water supplies, chemical injection equip-
ment must be separated from the water supply by an ap-
proved air gap separation or a reduced pressure principle
assembly that is approved by the Foundation for CCC
and the Hydraulic Research Institute. The equipment
must also comply with ASSE #1013 to protect the water
supply from back-siphonage and back-pressure.
3. For other water supplies, Florida State law, EPA regula-
tions, or other applicable local codes must be followed.
In the absence of legal guidelines at least a PVB should
be used.

gether, controlled, or connected through a master system then
the depths in Chart B shall apply.
2. Make all pipe joints and connections according to man-
ufacturer's recommendations. Perform all sol vent- weld
connections in accordance with ASTM D 2855.
3 . Minimum clearances shall be maintained between irriga-
tion lines and other utilities. In no case shall one irriga-
tion pipe rest upon another. Comingling or mixing of
different types of pipe assemblies shall be prohibited.
4. Thrust blocks must be used on all gasketed PVC systems.
They must be formed against a solid, hand-excavated
trench wall undamaged by mechanical equipment. They
shall be constructed of concrete, and the space between
the pipe and trench shall be filled to the height of the out-
side diameter of the pipe. Size thrustblocks in accor-
dance with ASAE S-376.1.
5. The trench bottom must be uniform, free of debris, and of
sufficient width to properly place pipe and support it
over its entire length. Native excavated material may be
used to backfill the pipe trench. However, the initial
backfill material shall be free from rocks or stones larger
than 1-inch in diameter. At the time of placement, the
moisture content of the material shall be such that the re-
quired degree of compaction can be obtained with the
backfill method to be used. Blocking or mounding shall
not be used to bring the pipe to final grade.
6. Pipe sleeves must be used to protect pipes or wires in-
stalled under pavement or roadways. Use pipe sleeves
two pipe sizes larger than the carrier pipe or twice the di-
ameter of the wire bundle to be placed under the paving
F.10
2007 FLORIDA BUILDING CODE— PLUMBING
APPENDIX F
or roadway, and extending a minimum of 3 feet beyond
the paved area or as required by the Florida Department
of Transportation (FDOT). Use sleeve pipe with wall
thickness at least equal to the thickness of schedule 40 or
PR 160 pipe, whichever is thicker. Proper backfill and
compaction procedures should be followed.
B. Control Valve Installation.
1. Valve installation shall allow enough clearance for
proper operation and maintenance. Where valves are in-
stalled underground, they shall be provided with a valve
box with cover extending from grade to the body of the
valve. The top of the valve body should have a minimum
of 6 inches (152 mm) of cover in nontraffic and nonculti-
vated areas and 18 inches (457 mm) of cover in traffic ar-
eas. If an automatic valve is installed under each
sprinkler, then the valve box may be omitted.
2. Install valve boxes so that they do not rest on the pipe, the
box cover does not conflict with the valve stem or inter-
fere with valve operation, they are flush with the ground
surface and do not present a tripping hazard or interfere
with routine maintenance of the landscape.
3. Install quick coupling valves on swing joints or flexible
pipe with the top of the valve at ground level.
Any above-ground manually-operated valves on nonpotable
water systems will be adequately identified with distinctive
purple colored paint. Do not provide hose connections on irri-
gation systems that utilize nonpotable water supplies.
C. Sprinkler Installation.
1 . On flat landscaped areas, install sprinklers plumb. In ar-
eas where they are installed on slopes, sprinklers may be
tilted as required to prevent erosion. Sprinklers should be
adjusted to avoid unnecessary discharge on pavements
and structures. Adjust sprinklers so they do not water on
roads.
2. Provide a minimum separation of 4 inches (102 mm) be-
tween sprinklers and pavement. Provide a minimum sep-
aration of 12 inches (305 mm) between sprinklers and
buildings and other vertical structures. Piping must be
thoroughly flushed before installation of sprinkler noz-
zles. Surface mounted and pop-up heads shall be in-
stalled on swing joints, flexible pipe, or polyethylene
(PE) nipples. Above-ground (riser mounted) sprinklers
shall be mounted on Schedule 40 PVC or steel pipe and
be effectively stabilized.
D. Pump Installation.
1. Install pumps as per the manufacturers recommenda-
tions. Set pumps plumb and secure to a firm concrete
base. There should be no strain or distortion on the pipe
and fittings. Pipe and fittings should be supported to
avoid placing undue strain on the pump. Steel pipe
should be used on pumps 5 horsepower (hp) or larger
whenever practical.
2. Pumps must be installed in a manner to avoid loss of
prime. Install suction line to prevent the accumulation of
air pockets. All connections and reductions in suction
pipe sizes should be designed to avoid causing air pock-
ets and cavitation.
3. Pumps must be located to facilitate service and ease of
removal. Appropriate fittings should be provided to al-
low the pump to readily be primed, serviced, and
dis-connected. Provide an enclosure of adequate size and
strength, with proper ventilation, to protect the pump
from the elements (except residential systems).
E. Low Voltage Wire Installation.
1. Install low voltage wire (30 volts or less) with a mini-
mum depth of cover of 12 inches (305 mm). Provide a
sufficient length of wire at each connection to allow for
thermal expansion/shrinkage. As a minimum, provide a
12-inch (305 mm) diameter loop at all splices and con-
nections. Terminations at valves will have 24 inches
(610 mm) minimum free wire.
2. Install all above-ground wire runs and wire entries into
buildings in electrical conduit. Provide common wires
with a different color than the power wires (white shall
be used for common wires). Connections are to be made
using UL approved devices specifically designed for di-
rect burial. All splices shall be enclosed within a valve
box.
F. Hydraulic Control Tubing.
1 . For hydraulic control systems, use a water supply that is
filtered and free of deleterious materials, as defined by
the hydraulic control system manufacturer. Install a
backflow prevention device where the hydraulic control
system is connected to potable water supplies.
2. Install tubing in trenches freely and spaced so that it will
not rub against pipe, fittings, or other objects that could
score the tubing, and with a minimum 12- inch (305 mm)
diameter loop at all turns and connections. Provide a
minimum depth of cover of 12 inches (305 mm).
3. Connect tubing with couplings and collars recom-
mended by the tubing manufacturer. All splices shall be
2007 FLORIDA BUILDING CODE— PLUMBING
F.11
APPENDIX F
made in valve boxes. Prefill tubing with water, expelling
entrapped air and testing for leaks prior to installation.
Install exposed tubing in a protective conduit manufac-
tured from Schedule 40 UV protected PVC or electrical
conduit.
PART VI: TESTING & INSPECTIONS
A. Purpose. All materials and installations covered by the Irri-
gation Code shall be inspected by the governing agency to ver-
ify compliance with the Irrigation Code.
B. Rough Inspections. Rough inspections will be performed
throughout the duration of the installation. These inspections
will be made by the governing agency to ensure that the instal-
lation is in compliance with the design intent, specifications,
and the Irrigation Codes. Inspections will be made on the fol-
lowing items at the discretion of the governing agency:
1. Sprinkler Layout and Spacing: This inspection will
verify that the irrigation system design is accurately in-
stalled in the field. It will also provide for alteration or
modification of the system to meet field conditions. To
pass this inspection, sprinkler/emitter spacing should be
within ± 5 percent of the design spacing.
2. Pipe Installation Depth: AH pipes in the system shall be
installed to depths as previously described in this code.
Test all mainlines upstream of the zone valves as fol-
lows:
a. Fill the completely installed pipeline slowly with water
to expel air. Allow the pipe to sit full of water for 24
hours to dissolve remaining trapped air.
b. Using a metering pump, elevate the water pressure to the
maximum static supply pressure expected and hold there
for a period of 2 hours, solvent-weld pipe connections
shall have no leakage.
c. For gasketed pipe main lines add water as needed to
maintain the pressure. Record the amount of water added
to the system over the 2-hour period.
d. Use the following formulas to determine the maximum
allowable leakage limit of gasketed pipe.
DUCTILE IRON:
L = S DP/ 133,200

allowable leakage (gph),
number of joints,
nominal diameter of pipe (inches),
average test pressure (psi), and
length of pipe (fi).
e. When testing a system, which contains metal-seated
valves, an additional leakage per closed valve of 0.078
gph/inch of nominal valve size is allowed.
C. Final Inspection. When the work is complete the contractor
shall request a final inspection.
1. Cross Connection Control and Backflow Prevention.
a. Public or domestic water systems: Check that an ap-
proved backflow prevention assembly is properly
installed and functioning correctly. Review the lo-
cation of the assembly to check that it is not creating
a hazard to pedestrians or vehicular traffic.
b. Water systems other than public or domestic water
systems: Check that the proper backflow prevention
assemblies are provided.
c. All assemblies that can be, will be tested by a certi-
fied technician prior to being placed into service.
2. Sprinkler Coverage Testing.
a. All sprinklers must be adjusted to minimize
overspray onto buildings and paved areas.
b. All sprinkler controls must be adjusted to minimize
runoff of irrigated water.
c. All sprinklers must operate at their design radius of
throw. Nozzle sizes and types called for in the sys-
tem design must have been used.
d. Spray patterns must overlap as designed.
e. Sprinklers must be connected, as designed, to the
appropriate zone.
D. Site Restoration.
1 . All existing landscaping, pavement, and grade of areas
affected by work must be restored to original condition
or to the satisfaction of the governing authority.
Verify that the pipeline trenches have been properly
compacted to the densities required by the plans and
specifications.
