National Plumbing Code of Canada 2015
The National Plumbing Code of Canada 2015 (NPC) sets out technical provisions for the design and installation of new plumbing systems and also applies to the extension, alteration, renewal and repair of existing plumbing systems. Twenty-eight technical changes are incorporated in the NPC 2015, increasing design and material choices and introducing water-use efficiency for plumbing fixtures, supply fittings and shower heads. The new water-efficiency requirements aim to reduce water usage in all buildings, regardless of water source. The Environment objective, already in the National Energy Code for Buildings and the National Building Code, was also introduced into the NPC 2015 to address “excessive use of water.”
The National Plumbing Code of Canada 2015, together with the National Building Code of Canada 2015, the National Energy Code of Canada for Buildings 2017 and the National Fire Code of Canada 2015, is an objective-based National Model Code that can be adopted by provincial and territorial governments. Codes Canada are developed by the Canadian Commission on Building and Fire Codes (CCBFC).
In Canada, provincial and territorial governments have the authority to enact legislation that regulates the design and installation of plumbing systems within their jurisdictions. This legislation may include the adoption of the National Plumbing Code (NPC) without change or with modifications to suit local needs, and the enactment of other laws and regulations regarding plumbing system design and installation, including the requirements for professional involvement.
The NPC is a model code in the sense that it helps promote consistency among provincial and territorial plumbing codes. Persons involved in the design or installation of plumbing systems should consult the provincial or territorial government concerned to find out which plumbing code is applicable.
This edition of the NPC succeeds the 2010 edition.
