1 CHAPTER 26 GENERAL PLUMBING REQUIREMENTSSECTION provisions of this CHAPTER shall govern theinstallation of PLUMBING not specifically covered in other chap-ters applicable to PLUMBING systems. The installation of plumb-ing,appliances, equipmentand systems not addressed by thiscode shall comply with the applicable provisions of theFloridaBuilding Code, fixtures, drains andappli-ancesused to receive or discharge liquid wastes or sewage shallbe connected to the sanitary drainage system of the building orpremises in accordance with the REQUIREMENTS of this section shall not be construed to prevent indirect Flood hazard areas prone to flooding asestablished by Table (1)
2 , PLUMBING fixtures, drains, andappliancesshall be located or installed in accordance with Sec-tion P2602 INDIVIDUAL WATER SUPPLYAND SEWAGE water-distribution and drainage systemof any building or premises where PLUMBING fixtures areinstalled shall be connected to a public water supply or sewersystem, respectively, if available. When either a publicwater-supply or sewer system, or both, are not available, orconnection to them is not feasible, an individual water supplyor individual (private) sewage-disposal system, or both, shallbe Flood-resistant areas prone to flood-ing as established by Table (1):1.
3 Water supply systems shall be designed and constructedto prevent infiltration of Pipes for sewage disposal systems shall be designed andconstructed to prevent infiltration of floodwaters into thesystems and discharges from the systems into P2603 STRUCTURAL AND PIPING the process of installing or repairing anypart of a PLUMBING and drainage installation, the finishedfloors, walls, ceilings, tile work or any other part of the buildingor premises that must be changed or replaced shall be left in asafe structural condition in accordance with the requirementsof the building portion of this Drilling and structuralmembers shall not be drilled, notched or altered in any mannerexcept as provided in Sections , , Holes, cutting and notching in cold-formed steellight-frame members shall be in accordance with AISI insulated panels (SIPs)
4 Shall be drilled and notchedor altered in accordance with the provisions of Section Protection against physical con-cealed locations, where piping, other than cast-iron or gal-vanized steel, is installed through holes or notches in studs,joists, rafters or similar members less than 11/2inches (38mm) from the nearest edge of the member, the pipe shall beprotected by steel shield plates. Such shield plates shall havea thickness of not less than inch ( mm) (No. 16 Gage). Such plates shall cover the area of the pipe where themember is notched or bored, and shall extend a minimum of2 inches (51 mm) above sole plates and below top Breakage and passing through orunder walls shall be protected from breakage.
5 Pipes passingthrough concrete or cinder walls and floors, cold-formed steelframing or other corrosive material shall be protected againstexternal corrosion by a protective sheathing or wrapping orother means that will withstand any reaction from lime and acidof concrete, cinder or other corrosive material. Sheathing orwrapping shall allow for movement including expansion andcontraction of piping. Minimum wall thickness of materialshall be inch ( mm).Exception:Sleeving is not required for installation ofCPVC into concrete or similar sleeves around pip-ing penetrating concrete slab-on-grade floors shall notbe of cellulose-containing materials.
6 If soil treatment isused for subterranean termite protection, the sleeve shallhave a maximum wall thickness of inch, and besealed within the slab using a non-corrosive clampingdevice to eliminate the annular space between the pipeand the sleeve. No termiticides shall be applied inside spaces between sleeves and pipesshall be filled or tightly caulked asapprovedby thebuildingofficial. Annular spaces between sleeves and pipes in fire-ratedassemblies shall be filled or tightly caulked in accordance withthe building portion of this FLORIDA BUILDING CODE Pipes through footings or foundation that passes under a footing or through a foundation wallshall be provided with a relieving arch.
7 Or there shall be builtinto the masonry wall a pipe sleeve two pipe sizes greater thanthe pipe passing localities having a winter design tempera-ture of 32 F (0 C) or lower as shown in Table (1) of thiscode, a water, soil or waste pipe shall not be installed outside ofa building, in exterior walls, in attics or crawl spaces, or in anyother place subjected to freezing temperature unless adequateprovision is made to protect it from freezing by insulation orheat or both. Water service pipe shall be installed not less than12 inches (305 mm) deep and not less than 6 inches (152 mm)below the frost Sewer sewersthat connect toprivate sewage disposal systems shall be a minimum of[NUMBER] inches (mm) below finishedgradeat the point ofseptic tank sewersshall be a minimumof [NUMBER] inches (mm) P2604 TRENCHING AND Trenching and trenches are exca-vated such that the bottom of the trench forms the bed for thepipe, solid and continuous load-bearing support shall be pro-vided between joints.
8 Where over-excavated, the trench shall bebackfilled to the propergradewith compacted earth, sand, finegravel or similar granular material. Piping shall not be sup-ported on rocks or blocks at any point. Rocky or unstable soilshall be over-excavated by two or more pipe diameters andbrought to the propergrade with suitable compacted Common Section shall be free from discardedconstruction material and debris. Backfill shall be free fromrocks, broken concrete and frozen chunks until the pipe is cov-ered by at least 12 inches (305 mm) of tamped earth. Backfillshall be placed evenly on both sides of the pipe and tamped toretain proper alignment.
9 Loose earth shall be carefully placedin the trench in 6-inch (152 mm) layers and tamped in Protection of installed parallel tofootings shall not extend below the 45-degree ( rad) bearingplane of the bottom edge of a wall or footing (see Figure ).SECTION shall be supported in accordancewith the following:1. Piping shall be supported to ensure alignment and pre-vent sagging, and allow movement associated with theexpansion and contraction of the piping Piping in the ground shall be laid on a firm bed for itsentire length, except where support is otherwise Hangers and anchors shall be of sufficient strength tomaintain their proportional share of the weight of pipeand contents and of sufficient width to prevent distortionto the pipe.
10 Hangers and strapping shall be ofapprovedmaterial that will not promote galvanic action. Rigid sup-port sway bracing shall be provided at changes in direc-tion greater than 45 degrees ( rad) for pipe sizes 4inches (102 mm) and Piping shall be supported at distances not to exceed thoseindicated in Table FLORIDA BUILDING CODE RESIDENTIALGENERAL PLUMBING REQUIREMENTSFor SI: 1 degree = LOCATION WITH RESPECT TO FOOTINGSSECTION P2606 WATERPROOFING OF and exterior wall penetrations shall bemade water tight. Joints at the roof, around vent pipes, shall bemade water tight by the use of lead, copper or galvanized ironflashings or anapprovedelastomeric material.
