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."

SECTION 202 
GENERAL DEFINITIONS 

ACCEPTED ENGINEERING PRACTICE. That which 
conforms to accepted principles, tests or standards of nation- 
ally recognized technical or scientific authorities. 

ACCESS (TO). That which enables a fixture, appliance or 
equipment to be reached by ready access or by a means that first 
requires the removal or movement of a panel, door or similar 
obstruction (see "Ready access"). 

ACCESS COVER. A removable plate, usually secured by 
bolts or screws, to permit access to a pipe or pipe fitting for the 
purposes of inspection, repair or cleaning.

allow air to enter the plumbing drainage system when negative 
pressures develop in the piping system. The device shall close 
by gravity and seal the vent terminal at zero differential pres- 
sure (no flow conditions) and under positive internal pressures. 
The purpose of an air admittance valve is to provide a method 
of allowing air to enter the plumbing drainage system without 
the use of a vent extended to open air and to prevent sewer 
gases from escaping into a building. 

AIR BREAK (Drainage System). A piping arrangement in 
which a drain from a fixture, appliance or device discharges 
indirectly into another fixture, receptacle or interceptor at a 
point below the flood level rim and above the trap seal. 



AIR GAP (Drainage System). The unobstructed vertical dis- 
tance through the free atmosphere between the outlet of the 
waste pipe and the flood level rim of the receptacle into which 
the waste pipe is discharging. 

AIR GAP (Water Distribution System). The unobstructed 
vertical distance through the free atmosphere between the low- 
est opening from any pipe or faucet supplying water to a tank, 
plumbing fixture or other device and the flood level rim of the 
receptacle. 

ALTERNATIVE ENGINEERED DESIGN. A plumbing 
system that performs in accordance with the intent of Chapters 
3 through 12 and provides an equivalent level of performance 
for the protection of public health, safety and welfare. The sys- 
tem design is not specifically regulated by Chapters 3 through 
12.

fluid under positive pressure that passes through an integral 
orifice or constriction, causing a vacuum. Aspirators are also 
referred to as suction apparatus, and are similar in operation to 
an ejector. 

BACKFLOW. Pressure created by any means in the water dis- 
tribution system, which by being in excess of the pressure in the 
water supply mains causes a potential backflow condition. 

Backpressure, low head. A pressure less than or equal to 
4.33 psi (29.88 kPa) or the pressure exerted by a 10-foot 
(3048 mm) column of water.

water into the potable water system as a result of the pres- 
sure in the potable water system falling below atmospheric 
pressure of the plumbing fixtures, pools, tanks or vats con- 
nected to the potable water distribution piping. 

Backwater valve. A device or valve installed in the build- 
ing drain or sewer pipe where a sewer is subject to backflow,

DEFINITIONS 



CRITICAL LEVEL (C-L). An elevation (height) reference 
point that determines the minimum height at which a backflow 
preventer or vacuum breaker is installed above the flood level 
rim of the fixture or receptor served by the device. The critical

arrangement between two otherwise separate piping systems, 
one of which contains potable water and the other either water 
of unknown or questionable safety or steam, gas or chemical, 
whereby there exists the possibility for flow from one system to 
the other, with the direction of flow depending on the pressure 
differential between the two systems (see "Backflow"). 

DEAD END. A branch leading from a soil, waste or vent pipe; 
a building drain; or a building sewer, and terminating at a 
developed length of 2 feet (610 mm) or more by means of a 
plug, cap or other closed fitting. 

DEPTH OF WATER SEAL. The depth of water that would 
have to be removed from a full trap before air could pass 
through the trap. 

1 1 DESIGN FLOOD ELEVATION. See Section 309.1. 

DEVELOPED LENGTH. The length of a pipeline measured 
along the centerline of the pipe and fittings. 

DISCHARGE PIPE. A pipe that conveys the discharges from 
plumbing fixtures or appliances. 

DRAIN. Any pipe that carries wastewater or water-borne 
wastes in a building drainage system. 

DRAINAGE FITTINGS. Type of fitting or fittings utilized in 
the drainage system. Drainage fittings are similar to cast-iron 
fittings, except that instead of having a bell and spigot, drain- 
age fittings are recessed and tapped to eliminate ridges on the 
inside of the installed pipe. 

DRAINAGE FIXTURE UNIT 

Drainage (dfu). A measure of the probable discharge into 
the drainage system by various types of plumbing fixtures. 
The drainage fixture-unit value for a particular fixture 
depends on its volume rate of drainage discharge, on the 
time duration of a single drainage operation and on the aver- 
age time between successive operations. 

DRAINAGE SYSTEM. Piping within a public or private 
premise that conveys sewage, rainwater or other liquid wastes 
to a point of disposal. A drainage system does not include the 
mains of a public sewer system or a private or public sewage 
treatment or disposal plant. 

Building gravity. A drainage system that drains by gravity 
into the building sewer.

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.

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.

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.

C103.9.2 Seepage trench excavations. Seepage trench 
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 
trench area. Distribution piping in a seepage bed shall be 
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 
synthetic materials or 9 inches (229 mm) of uncompacted 
marsh hay or straw. Building paper shall not be used to 
cover the aggregate. A minimum of 9 inches (229 mm) of 
soil backfill shall be provided above the covering.

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

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. 



2007 FLORIDA BUILDING CODE— PLUMBING 



E.3 



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.

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.

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.

* Except in areas where more than one lot is connected to- 
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.

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.
