11、ion.iiiOrigin and DevelopmentThe advantages of a statewide adopted Uniform Plumbing Code are recognizedthroughout the industry. Disorder in the industry because of widely divergent plumbingpractices and the use of many different, often conflicting, plumbing codes by localjurisdictions influenced the

12、 Western Plumbing Officials Association (now the InternationalAssociation of Plumbing and Mechanical Officials IAPMO) to form a committee. Thiscommittee of plumbing inspectors, master and journeyman plumbers, and plumbingengineers, backed by public utility companies and the plumbing industry to crea

13、te abasic plumbing document for general use. The product of this effort, the first edition ofthe Uniform Plumbing Code(UPC) was adopted by IAPMO in 1945. The widespreaduse of this code over the past seven decades by jurisdictions throughout the UnitedStates and internationally is testament to its me

14、rit.Publishing the 2003 Uniform Plumbing Code, is a significant milestone because it is thefirst time in the history of the United States, a plumbing code was developed through atrue consensus process. The 2015 edition represents the most current approaches in theplumbing field and is the fifth edit

16、des consumers with safe and sanitary plumbingsystems while, at the same time, allowing latitude for innovation and new technologies.The public at large is invited and encouraged to take part in IAPMOs open consensuscode development process. This code is updated every three years. The UniformPlumbing

17、 Code is dedicated to all those who, in working to achieve “the ultimateplumbing code,” have unselfishly devoted their time, effort, and personal funds to createand maintain this, the finest plumbing code in existence today.The Uniform Plumbing Code updates every three years in revision cycles that

18、begin twiceeach year that takes two years to complete. Each revision cycle advances according to a published schedule that includes final datesfor all major events and contains four basic steps as follows:1. Public and Committee Proposal Stage;2. Comment Stage;3. Association Technical Meeting;4. Cou

19、ncil Appeals and Issuance of Code.IAPMO develops “full consensus” codes built on a foundation of maximum participation andagreement by a broad range of interests. This philosophy has led to producing technicallysound codes that promote health and safety, yet do not stifle design or development. It i

20、s important to stress that; the process remains committed to the principles of consensuscode development where consensus Technical Committees and Correlating Committeesrevise codes. The public and membership is offered multiple opportunities to debate,provide input and raise concerns through Amendin

35、ons addressed within the chapters and appendices of theUniform Plumbing Code:Chapter 1 Administration. Chapter 1 regulates the application, enforcement, and administration of subsequent requirements of the code. As well asestablishing the scope of the code, this chapter is concerned with enforcing t

36、he requirements contained in the body of the code.A plumbing code, as with any other code, is intended to be adopted as a legally enforceable document to safeguard health,safety, property and public welfare. The code cannot be effective without satisfactory provisions for its administration andenfor

37、cement. The Authority Having Jurisdiction is to review the proposed and completed work and to decide whether a plumbingsystem conforms to the code requirements. As a public servant, the Authority Having Jurisdiction enforces the code in anunbiased, proper manner. The design professional is responsib

38、le for the design of a safe plumbing system. The contractor isresponsible for installing the system in accordance with the plans. Chapter 2 Definitions. To maintain consistency and encourage the use of common terminology, Chapter 2 establishes definitions to provide clarityof terms and promote the u

39、se of a common language throughout the code. Understanding definitions within the context oftheir application enables greater collaboration, efficiency, standardization and interpretation in applying and enforcing termsused throughout the code. Codes are technical documents, and every term can impac

40、t the meaning of the code text. Termsnot defined have a normally accepted meaning.Chapter 3 General Regulations. Chapter 3 regulates the general requirements, not specific to other chapters, for installing plumbing systems. Manyregulations are not specific plumbing requirements, but relate to the ov

41、erall plumbing system. This chapter contains safetyrequirements for installing plumbing and also contains nonplumbing requirements for identifying pipe, pipe fittings, traps,fixtures, materials and devices used in plumbing systems. Listing or labeling method of approval, based on applicablenationall

42、y recognized standards, for the safe and proper installation of plumbing systems is essential to ensure protection ofpublic health, safety, and welfare. The safety requirements provide protection for piping, material, and structures, withprovisions for installation practices, removing stress and str

43、ain of the pipe, sleeving, and hanger support. The buildingsstructural stability is protected by the regulations for cutting and notching of structural members. Chapter 4 Plumbing Fixtures and Fixture Fittings.This chapter regulates the minimum number of plumbing fixtures of a specific type and qual

44、ity for each building. The fixturesmust be properly installed to be usable by the individuals occupying the building. The quality and design of every fixturemust conform to the applicable referenced standard. Compliance with this chapter will result in a building or structure havingacceptable plumbi

45、ng fixtures for the sanitary, hygienic, cleaning, washing and food preparation needs of the occupants.Chapter 5 Water Heaters. Chapter 5 regulates the design, approval, installation, and safety devices of fuel burning and other types of water heaterswith the combustion air requirements for ventilati

46、on and dilution of flue gases for appliances installed in buildings. Thischapter does not apply to direct vent appliances. In addition, this chapter regulates the design, construction, installation,maintenance of chimneys, vents and their connections to fuel burning appliances. Methods to supply com

47、bustion air may besupplied from an indoor air supply, outdoor air supply, a combination of indoor and outdoor air supply, mechanical airsupply, or an engineered system. Combustion air provisions are based on the number of openings and the total openingsize required based on the total energy input ra

48、ting of the appliance. Acceptable air supply for combustion and ventilation isnecessary for proper operation of fuel burning appliances. A shortage of combustion air can result in incomplete combustionand production of poisonous gases, such as carbon monoxide or appliance overheating. Ventilation ai

49、r provides cooling forthe appliance casing and internal controls. Inadequate ventilation of the space in which an appliance is installed can resultin increased surrounding temperatures that stress the appliance itself or other appliances in the vicinity. Chapter 6 Water Supply and Distribution. Chapter 6 regulates the design, material and installation of water supply and distribution systems, including residential firesprinklers. The water supply and distrib
