Prepared under the auspices of the Canadian Commission on Building and Fire Codes.
Published by the National Research Council of Canada, 2005.


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. If you're unclear on a technical point, chances are the appendix can shed light on it.

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.

Since the publication of the previous edition in 1995, all three National Construction Codes have undergone extensive reviews and changes that now make the 2005 editions clearer, easier to apply to renovation and more accommodating to technological innovation. New to the 2005 Code:
  • Over 200 technical changes in the 2005 NPC
  • New information, namely the objectives and functional statements, designed to improve clarity and consistency in the application of the codes' requirements
  • A new organizational layout. The Code comprises three divisions: Divisions A, B and C
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 1995 Code provisions updated with technical changes. Most of the Code structure and vocabulary that users are familiar with remain the same, which will make getting used to the new Codes much easier.

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

All requirements in the 2005 NPC are linked to one or more of the following three top-level objectives:
  • Safety
  • Health
  • Protection of Buildings and Facilities from Water and Sewage Damage
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 2005 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.
Price and availability subject to change. Shipping and applicable taxes extra.
