6 2012 Plumbing Codes Overview The International Plumbing Code (IPC) and the Uniform Plumbing Code (UPC) cover the initial design of plumbing systems through the installation and construction phases, and into the maintenance of operating systemsFuel-gas appliances and systems are addressed in the 2012 International Fuel Gas Code (IFGC)
7 2012 Plumbing Codes How did we get here? Applicants have the choice to use the 2012 IPC or 2012 UPCThe 2012 IPC is a performance-based codeThe 2012 UPC is a prescriptive codeBoth codes cover similar topicsThere are also differencesHow did we get here?
8 Code Adoption ProcessCity staff committee researches and prepares recommendationsObtain input from stakeholdersStaff and public recommendations presented to DAB Technical SubcommitteeDAB Subcommittee presents recommendations to full DAB committeeCity Council Subcommittee reviewCity Council for final adoption vote
9 Code Adoption ProcessStaff committee completed a chapter comparison between the two codes and received input from City departments, industry and the publicStaff made a presentation to DAB Technical Subcommittee with recommendation to adopt the UPCDAB Technical Subcommittee heard testimony and moved recommendation to full DAB for voteFull DAB committee deadlocked and moved recommendation to City Council subcommitteeCity Council Subcommittee voted to adopt IPCCity Council directed adoption of both codes
10 2012 Plumbing Codes Next staff challenge, review both codes Determine if amendments requiredShould codes remain distinct?What is the same and different?Mixing of codes allowed?How will it affect review and inspections?What about licensing?
11 Code AmendmentsOnce a decision was made on the codes, amendments were made to adapt the code to local conditions and existing ordinancesStaff and public submitted IPC and UPC amendments for considerationAmendments were available for public viewing on our website with written reasons behind each changeAll amendments were passed through the code adoption process
13 2012 Common Amendments Minimum plumbing fixture calculation Drinking fountains and water dispensersBackflow prevention devicesInstallation of low slope sewersTrap seal protectionGrease interceptorsRainwater drainage systems
14 Minimum Plumbing Fixtures UPC Table 422.1, IPC Table 403.1Tables from IBC, IPC, and UPC all matchDeleted requirements for service sinksUse 15 occupants as threshold for separate restrooms, 50 in Group B and MUrinal substitution back to 50%
15 Drinking Fountains UPC 415.2, IPC 410.3 Tables from IBC, IPC, and UPC all matchDrinking fountains not required for occupant load of 50 or less in all occupanciesDefined water dispensers and water coolersIn occupancies where drinking fountains are required, water dispensers may be substituted for not more than 50% of the required number of drinking fountains
17 Low Slope Sewers UPC 718.1, IPC 704.1 Exception: The Authority Having Jurisdiction may approve a lessor slope for building sewers in lieu of a sewage ejector or pumping station when a registered engineer or architect certifies the building sewer design and its installation, and when the building owner agrees in writing under notary to accept the lessor slope. Certification of the building sewer shall meet the special inspection requirements of the Phoenix Building Construction Code
18 Trap Seal Protection UPC 1007.1, IPC 1002.4 Exception: Trap seal primer valves are not required when an alternative device is provided to prevent evaporation of the liquid seal. Barrier type floor drain devices used to prevent evaporation shall conform to ASSE 1072, be accessible for maintenance and installed in accordance with manufacturer’s instructions. A source of water for filling of traps shall be located in the vicinity of the plumbing fixture
19 Grease Interceptors UPC 1014, IPC 1003 Grease traps and interceptors are regulated by Water Services Department Environmental Services Division so codes need to matchDefinitionsWhere devices are requiredList of approved devicesFood waste disposal and dishwasher requirementsCapacity and sizing of devices
20 Rainwater Drainage Systems UPC Ch. 11, IPC Ch. 11Scupper location and sizing criteriaRainfall rate of 3 inches per hourSecondary drainsProhibition on combined systemsFood waste disposal and dishwasher requirementsCapacity and sizing of devices
21 Other Amendments UPC Chapter 12 Fuel Gas Piping was reserved due to possible conflicts with the 2012 International Fuel Gas CodeSizing tables are the same
22 Code Differences Water heater requirements Domestic water supply sizingSanitary drain pipe sizing and slopesDishwashing sink indirect versus directVenting options allowed, air admittance valvesCleanouts for rainwater drain systemsProvisions for alternate water systemsAppendicesTo be determined…..
23 Mixing of CodesPermit applicant is asked to identify the code used for plumbing designReview and inspection are then completed using the code referenced on the planIn certain cases it may be impractical to use different techniques such as pipe sizing or ventingSpecific items can be judged on a case-by-case basis by plan review and/or inspections
24 How Do We Make It Work?City and design community work together towards solutions through open dialogue and concentrating on what worksContinuous education for staff, designers and installersCity licensing to incorporate both codesBottom line is to insure safe and sanitary systems
