Prepared under the auspices of the Canadian Commission on Building and Fire Codes.
Published by the National Research Council of Canada, 2010.


The National Plumbing Code of Canada (NPC) is prepared for anyone who designs or installs plumbing systems. The body of the document contains the Plumbing Code regulations, and a helpful appendix provides numerous supporting diagrams and explanatory material. 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.

The Code specifies minimum requirements for draining systems, venting systems, water service pipes, and water distribution systems. Want to know how to prevent back-siphonage in buildings? Can you use a cast iron soil pipe in a water system? What is the minimum size of a water service pipe? The NPC provides answers to these questions - and hundreds more - clearly and logically.

Significant technical changes to the 2010 National Plumbing Code include:
  • Water Pipe Sizing

Division A includes compliance options and information on new elements called objectives and functional statements. Objectives describe the overall goals that a particular Code's provisions are intended to achieve. Functional statements describe the functions that a building or its components must perform to fulfill the objectives. At least one objective and one functional statement are linked to each technical requirement to help users better understand the reason why a particular requirement must be met and to help them evaluate alternative solutions.

In Division B, Code users can find the "acceptable solutions," which consist of the Code provisions updated with technical changes.

Finally, Division C contains administrative provisions, which have all been consolidated into this one place.

Under Canada's Constitution Act, plumbing regulation is the responsibility of provincial and territorial governments. The NPC is in the form of a model code to permit adoption by the appropriate authority. Most provinces and territories adopt or adapt the model NPC and enforce its requirements.

The National Plumbing Code of Canada is available in two practical formats:
  • A binder version that lies flat for easy reference easily accommodates updates.
  • A soft-cover version that contains the same information as the binder, at about half the weight. This format is ideal for the job site.
