The National Plumbing Code (NPC) sets out technical provisions for the design and installation of new plumbing systems. It also applies to the extension, alteration, renewal and repair of existing plumbing systems.
\nThe NPC establishes requirements to address the following four objectives, which are fully described in Division A of the Code:
\n\u2022 safety
\n\u2022 health
\n\u2022 protectionofbuildingsandfacilitiesfromwaterandsewagedamage \u2022 environment
\nCode provisions do not necessarily address all the characteristics of buildings and facilities that might be considered to have a bearing on the Code’s objectives. Through the extensive consensus process used to develop and maintain Codes Canada (see the section entitled Development of Codes Canada), the code-user community has decided which characteristics should be regulated through the NPC.
\nBecause the NPC is a model code, its requirements can be considered as the minimum acceptable measures required to adequately achieve the above-listed objectives, as recommended by the Canadian Commission on Building and Fire Codes. They become minimum acceptable requirements once they are adopted and passed into law or regulation by an authority having jurisdiction: i.e., the requirements represent the minimum level of performance required to achieve the objectives that is acceptable to the adopting authority.<\/p>\n","protected":false},"excerpt":{"rendered":"
