PREFACE

Introduction Internationally, codc officials recognize the need for a modern, up-to-date plumbing code addressing tlie design and installation of plumbing systctns thnjugh requirements emphasizing performance. The Ir'ten7ationc~l Plr~mbirig Coclele", in this 2006 edition. is designed to meet thcse nccds through ~nodcl codc regulations that safeguard the public health and safcty in all conlmunitics. large and small..

'l'his comprchensivc plumbing code establishes minimum regulations for plumbing systems using prcscriptive and perfor- mancc-relatcd provisions, It is founded on broad-based principles that makc possible the use of new tnatcrials and ncw plumbing dcsigns. This 2006 edition is fully compatible with all the 11itenzci.tioilal code.^'" (I-Codes") published by the 1nternation;ll Codc Council (ICC)", including thc Ir~fen~u?iorlnl Buildirzg CodeG), ICC Electriccrl Codecn, Irzter-riutionnl Erzer<yy (70~7.sc~r~,crtim Co~lc~~'), Ir~ter7zc~tiorrrrl E.vistir~g Building Codcw",rzten~ational Fire C,'odeCD, hzterriationtrl Fuel Gus Coele@, Inter.r7.utior~ul Mec.hnrziccl1 C,'o(jc~'!~, 1CC Pe:r:fiirrr~(~rice h~tenzc~tional Privcrte Sc~wc~gr Di.spo,sal Code'!;, Irztmzc~tiorinl Property Mc~irrrer~crr~ce Code"', 61terrln- tior~trl Resitkiriic~l Codc~", lrzterrlatiol1al M'ildland-(JrDarl lrltet-fhre Coclc~'" and hzter-r~atiorzal Zoning Corie"'.

Thc Intrrriertio~iul Plrrnzbirzg Code provisions provide Inany benefits, among which is thc niodcl codc devclopmci~t process that offers an intcniational forum for plu~nbing professionals to discuss performance and prescriptive codc requirerncnts. This fomm providcs a n exczllcrrt arena to debate proposeti revisiorrs. This model code also encourages international consistency in thc application of provisions.

Development The first cdition of the lr~ter-rlationul Plct~rzhi~~g Colf~ (1995) was the culmination of an effort initiated in I994 by a dcvcloplncnt coiil~nittcc appointcd by the ICC and consisting of representatives of the three statutory members of the International Cotic Council at that time, including: Building Officials and Codc Administrators International, Inc. (BOCA), International Co~lfercnce of Build- ing Officials (1CB0) and Southcm Building Codc Congress International (SBCCI). Thc intcnt was to draft a comprchensivc set of regulations for plurnbing systenls consistent with and inclusive of thc scope of the existing n~odel codes. Technical content of thc latest ]nodel codes pronlulgated by BOCA, ICBO and SBCCl was utilized as tlie basis for thc devclopnicnt. This 2006 edition prcs- cnts the code as origi~lally issued, with changes as reflected i n the subsequent editions through 2003 ane with changes approved through the ICC Codc Development Proccss through 2005. A new edition such as this is promulgated every three years.

'l'his codc is foundcd on principles intcnded to establish provisions consistent with the scope of a plumbing code that adcc]uately protccts public hcalth. safety and welfare; provisions that do not unnecessarily increasc constluction costs; provisions that do not rcstrict thc usc of new materials, products or methods of construction; and provisions that do not give preferential trcatnlcnt to particular typcs or classes of materials, products or methods of construction.

Adoption Thc Irzrer~rz~~tio~~al Pl~inlhirig Cmle is available for adoptio~r and use by jurisdictions internationally. Its use within a go\!ernmcntal jurisdiction is intcndctl to be acco~nplishcd through adoption by reference in accordance with proceedings cstablisliing the jurisdiction's laws. At thc time of adoption, jurisdictions sho~rld insert the appropriate inforniation in provisions requiring specific local information, s ~ ~ c h as thc name of thc adopting jurisdictioi~. These locations arc shown in braclcctcd words in small capital lcttcrs in the cotlc and in the sample ordinancc. The sample adoption ordinance on page v addresses several licy elements of a code adoption ordinance. including the information rcttuired for insertion into thc codc text.

Maintenance The I~zt~rr~c~tiorral Pl1~1rzbir1g Code is kept up to date through thc review of proposed changcs submitted by codc enSo~-cing officials, industry rcprescntatives, design professionals and other interested parties. Proposed changes are carefully cvnsidcrcrt through an open codc dcvelopnient proccss in which all interested and affected parties may participate.

The time for this amount of watcr to seep away shall be determined, and this procedure shall be repcated if the water from the sccond filling of the hole secps away in 1 0 minutes or less. Thc test shall procecd as follows: Watcr shall be addcd to a point not more than 6 inches (1 5 1 mm) above the gravel or coarse sand. Thereupon, from a tixcd refercncc point, water levels shall bc measul-cd at 10-minute intervals for a period of 1 hour. Wherc 6 inches ( 1 52 mm) of water seeps away in less than I 0 minutes, a shorter interval betwecn measurements shall bc used, but in no case shall the water dcpth exceed 6 inches (152 mm). Where 6 inches (152 mm) of watcr seeps away in less than 2 minutcs. the test shall be stopped and a rate of less than 3 minutes pcr inch (7.2 slmm) shall be reported. Thc final watcr level drop shall be uscd to cal- culate the percolation rate. Soils not mceting the abovc requirements shall be tested in accordance with Scctiou C103.7.1.3.

C103.7.1.3 Test procedure, other soils. Thc hole shall be tillcd with clear water, and a minimum water dcpth of 12 inches (305 mrn) shall be maintained abovc the bottom of the holc for a 4-hour period by refilling whcnever necessary or by use of an automatic siphon. Watcr remaining in the hole after 4 hours shall not bc rc~novcd. Thereafter. the soil shall be allowed to swell not less than 16 hours or more than 30 hours. Immcdiatcly aftcr the soil swelling pcriod. the mcasurcmcnts for dcterrnining the pcrcolation rate shall be made as follows: Any soil sloughed into the hole shall bc removeil and thc water Icvel shall be adjusted to 6 inchcs (152 mm) above the gravel or coarsc sand. Thcl-eupon, from a fixed refercncc point, the water lcvel shall be measured at 30-minute intervals for a period of 4 hours, unless two successive watcr level drops do not valy by more than 0.62 inch (1.59 mm). At least threc water lcvel drop5 shall be observed and recorded. The hole shall be f~l led with clcar watcr to a point not more than 6 inches (151 m ~ n ) abovc the gravel-or coarse sand whenever it becomcs ncarly empty. Adjustments of the water lcvel shall not be niadc during the three measurement periods cxccpt to the linl- its of the last measured water level drop. Whcn thc first 6 inchcs (1 52 nxn) of watcr seeps away in less than 30 min- ~rtes, 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 thc tinal ~ncasurement pcriod shall be ~ [ s c d in calculating thc percolation rate.

SlZllVG OF WATER PIPING SYSTEM

SECTION €101 GENERAL

ElOl.1 Scope.

I1:lOl.l.l This appendix outlines two procedures for sizing 3 watcr piping system (scc Sections E103.3 and E201.1). The dcsign procedures are based on the mi~iimum static pressure iivailablc from the snpply source, thc hcad charges in the system c a ~ ~ s c d by friction and elevation, and the rates of flow nccessary for operation of various fixtures.

E101.1.2 Because of the variable coliditions encountered in hydraulic dcsign, it is impractical to specify dcfinitc and detailed rules for sizing of the water piping system. Accord- ingly, other sizing or dcsign methods conforming to good cngincering practice standards arc acceptable alternatives to those presented herein.

SECTION El 02 INFORMATION REQUIRED

E102.1 Preliminary. Obtain the necessary information regarding the niiniilium daily static senrice pressure in the area where the building is to be located. If the building supply is to be mctcrcd, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes likely to be uscd. Friction loss data can be obtained from most n1anufact~1r- crs of water meters.

E102.2 Demand load.

E102.2.1 Estimate the supply demand of the building main and thc principal branches and risers of thc systcm by total- Ing the corresponding dcmand from the applicable part of Table E103.3(3).

3102.2.2 Estimate continuous supply demands in gallons pcr minute (Llm) for lawn spri~lklers, air conditioners, etc., and add the sum to the total demand for fixtures. The result is thc estimated supply demand for the building supply.

SECTION El83 SELECTION OF PIPE SIZE

E103.1 General. Dccitie from Table 604.3 what is the desir- able minimum residual pressure that should be maintained at the highest fixture in the supply systcm. If the highest group of fistures contains flush valves, the pressure for the group should not be less than 15 pounds per square inch (psi) (103.4 kR1) tlowing. For flush tank \upplics. the available pressure should not be less than 8 psi (55.2liPa) flowing, exccptblowout action fixtures must not be leu5 than 25 psi (173.4 kPa) flowing.

E103.2 Pipe sizing.

12103.2.1 I'ipc sizes can be sclccted according to the followin? procedure or by other dcsign methods conforming to acceptable engineering practice and approved by the adinin-

istrative authority. The sizes selected must not be le\s than the minimum rcquired by this code.

E103.2.2 Water pipc sizing proccdurcs are based on a system of pressure requirements and losses, thc sun1 of which must not exceed the minimum pressurc available at the supply source. These pressures are as follows:

1. Pressure rcquired at fixture to product rccluircti Ilow. See Sections 604.3 and 604.5.

2. Static pressurc loss or gain (due to hcad) is colnyutcd at 0.433 psi per foot (9.8 kPa1in) of clevaiio11 chalige.

Example: Assume that thc highest fixture supply outlet is 20 feet (6096 mm) above or below the supply source. This produces a static pressure differential of20 feet by 0.433 psilfoot (2090 mm by 9.8 W d m ) and an 8.66 psi (59.8 Wa) loss.

3. Loss through watcr meter. The friction or pressure loss can be obtaincd from lnetcr manufacturers.

4. Loss through taps in water main

5. Losses through special devices such as liltcrs. softeners: backflow prevention devices and pressure regulators. Thesc vducs must be obtained from the manufacturers.

6. Loss through valves and fittings. Lose s for these items arc calculated by converting to equivalent length of piping and add~ng to the total pipc length.

7. Loss due to pipe friction can be calculated when the pipe size, the pipe length ant1 the flow through the pipe are known. With these three items, the friction loss can be determined. For piping flow charts not included, use n~anufacturers' tables and velocity recommendations.

Note: For the purposes of all examples, the following metric conversions arc applicable:

1 cubic foot per minutc = 0.4719 Ws

1 square foot = 0.0929 m'

1 dcgree = 0.0 175 rad

1 p o ~ n d per square inch = 6.895 kPa

Solution: 4 tabular arrangement such as shown in Table E103.3(1) should first be constructed. The steps to be followed are indicatcd by the tabular arrangement itself as they arc in sequence, C O ~ L I I ~ ~ I I S I through 10 and lines A through L.

Step I

Columns 1 and 2: Divide thc system into sections breaking at major changes in elevation or where branches lead to tixture grc~ups. After point B [see Figure E103.3(1)], separate consideration will be given to the hot and cold watcr piping. Enter the sections to be considered in the service and cold water piping in Colun~n I of the tabular arrangcment. Col- umn 1 of Table E103.3(1) provides a line-by-line recoln- mended tabular arrangement forusc in solving pipc sizing.

The objective in designing the water supply system is to ensure an adecli~atc water supply and pressure to all fixtures and ccluipmcnt. Colunln 2 provides the pounds per square inch (psi) to be considered separately from the minimum pressure available at the main. Losses to take into consideration are the following: the differences in elevations between the water supply source and the highest water supply outlet, meter pressure losses, the tap in main loss, special fixture devices such as water softeners and bacldlow prevention dcvices and the prcssure required at the most remote fixture outlet. The difference in elevation can result in an incrcasc or decrease in available pressure at the main. Where the watcr supply outlet is located above the source. this rcsults in a loss in the available pressure and is subtracted from the pressure at the water sourcc. Where the highest water supply outlet is located below the water supply sourcc, thcrc will be an increase in pressure that is added to the available pressure of the water source.

Colunln 3: .According to Table E103.3(3). determine the gpm (L/m) of flow to be expected in each section of the system. These tlows range from 28.6 to 108 gprn. Load values for fixtures must be determined as water supply fixture units and then converted to a gallon-per-minute (gpm) rating to determine pcak dcmand. When calculating pcak demands, the water supply fixture units are added and then converted to the gallo11-per-minute rating. For contin~ious flow fixturcs such as hosc bibbs and lawn sprinlder systems, add the gallon-per-minute demand to the intermittent derlland of fixtures. For example, a total of 120 water supply fixture

Line B: Dcte~minc from Table 604.3 the highest pressure required for the fixtures on the system, which is 15 psi (103.4 Wa), to operate a flushometer valve. The most remote fixture outlct is neccssaly to compute the pressure lobs caused by pipe and fittings, anti represents the most downstream fixture along the circuit of piping requiring the available pressurc to operate properly as indicated by Table 604.3.

Line C: Determine the pressure loss for the lnctcr size given or assumed. The total water flow from the main through the service as determined in Step I will scrve to aid in the meter selected. There arc three common types of water meters: the pressure losses are detcrminetl by the American Water Works Association Standards for displacement type. coni- pound type and turbine type. The maximum pressure loss of such dcvices takes into consideration the meter size, safe operating capacity (gpm) and maximunl rates Tor continuous operations (gpm). Typically, equipment imparts grcater pressurc losses than piping.

Line D: Select from Table E103.3(4) and cntcr the pressure loss for the tap size given or assumed. The loss of prcssure through taps and tees in pounds per squarc inch (psi) arc based on the total gallon-per-minute flow rate and size of the tap.

Line E: Determine the difference in elevation bctwcen thc main andsource of supply and the highest fixture on the systern. Multiply this figure, expressed infect. by 0.43 psi (2.9 kPa). Enter the resulting psi loss on Line E. l'hc difference in clevation between the watcr supply source and the highcst water supply outlet has a significant impact on thc sizing of the water supply system. The difference in elevation usually results in a loss in the available pressurc because thc watcr supply outlet is generally located above thc watcr supply soiuce. The loss is caused by thc prcssure required to lift thc water to the o ~ ~ t l c t . The pressure loss is subtracted from the pressure at the water sourcc. Where thc highest watcr supply outlet is located below the watcr source, there will be an increase in prcssure which is addcd to the available pressurc of the water source.

Lines F, G and H: The pressure losses through filters. backflow prevention devices or other special fixtures must be obtained from the maniifacturcr or estimated and entcred on these lines. Equiplnent such as backflow prevcntion devices, check valves, water softeners, instantaneous or tankless water heaters, filters and strainers can impart a rnuch greater pressurc loss than the piping. The prcssure losses can range from 8 psi to 30 psi.

Coli~nln 8: Select from Figure E103.3(3) the friction loss per 100 fcet (30 480 mm) of pipc for the gallon-per-minute flow in a scction (Column 3) and trial pipe size (Column 5). M a x i m ~ ~ m friction hcad loss per 100 fcet is detcrnmined on thc basis of total pressure available for friction hcadloss and thc longest cquivalcnt lcngth of run. The selection is based on the gallon-per-minute demand, the uniform friction head loss, and the maximum dcsign vclocity. Wherc Ihe size indicated by hydraulic tablc indicates a velocity in cxcess of the sclcctcd vclocity, a sizc must be selccted which produces the required velocity.

Step 10

Column 9: M~~l t ip ly the tigures in Columns 7 and 8 for each hcction and cntcr in Column 9.

Total friction loss is determined by nlultiplying the friction loss per 100 fect (30 480 mm) for each pipe section in the total developed length by the pressure loss in fittings cxpressecl as equivalent length in feet. Note: Section C-F should be considered in the total pipe friction losses only if greater loss occurs in Scction C-F than i n pipe scction D-E. Seclion C-F is not considered in the total developed length. Total friction loss in equivalent length is dctermincd in Table E.2.

Stcp I1

Step 12

Line I,: Subtract Line J from Line K and enter in Colunln 10.

Thc result should always be a positive or plus figurc. I f it is not, repeat the operation using Colu~nns 5; 6 , s anct0 until a balance or near balance is obtained. If the difference bctween Lines J and K is a high positive numbcr, it is an indication that the pipe sizcs arc too large and should bc reduced, thus saving materials. In such a case, thc opcra- tions using Columns 5 ,6 ,8 and 9 should again be repeated.

The total friction losses are detennincd and subtracted from thc pressurc available to ovcrco'nc pipc friction for trial pipe size. This number is critical as it provides a guidc to whether the pipe size selectcd is too large and the process should be repeated to obtain an econon~ically dcsigncd system.

Answer: The final figurcs entered in Column 5 becolne thc design pipe sizc for the respective sections. Rcpcating this operation a second time using thc srtlne sketch but consider- ing the demand for hot water, it is possible to size thc ]lot watcr distribution piping. This has been worked up as a part of the overall problem in the tabular arrangemcnt used for sizing the service and water distribution piping. Note that consideration must be given to the prcssurc losses from thc strcct main to the water heater (Section A-B) in determining thc hot water pipc sizcs.
