National Plumbing Code of Canada 2005

The 2005 edition of the National Plumbing Code of Canada (NPC) is now available. Over 200 technical changes have been incorporated in this new edition. The 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.

New information has been added to make the NPC 2005 clearer, easier to apply to existing plumbing systems and more accommodating to innovation. It explains the objectives that the Code's provisions are intended to achieve and describes the functions that a plumbing system or its components must perform to fulfill these objectives.

The NPC also has a new organizational layout that comprises three divisions: Divisions A, B and C. Division A includes the compliance options, the objectives and the functional statements. Division B contains the provisions — now referred to as "acceptable solutions" - relating to such issues as materials and equipment, piping, drainage systems, venting systems and potable and non-potable water systems. Division C contains administrative provisions.

The NPC 2005 is a must-have for anyone who designs or installs plumbing systems.
