Abstract	The National Plumbing Code of Canada (NPC) 2020, developed by the Canadian Commission on Building and Fire Codes and published by the National Research Council of Canada, sets out technical requirements for the design and installation of new plumbing systems, as well as the extension, alteration, renewal and repair of existing plumbing systems. Over 50 technical changes have been incorporated in this new edition, improving the level of safety, health, water-use efficiency, and protection from water and sewage damage provided by the Code, and expanding design and material options. Significant changes in the NPC 2020 • Fibrocement pipe and fittings are included as alternatives to asbestos-cement materials, which were removed from the NPC 2015 as an interim change. • Other new plumbing materials are added as options, including polyethylene of raised temperature (PE-RT) tube, cellular core polyvinyl chloride (PVC) pipe, and their fittings. • The maximum temperature for water discharging from shower heads or into bathtubs is reduced in healthcare facilities and seniors’ residences to prevent scalding. • Gate valves and screw caps, which require manual intervention, are removed as options for backflow protection to reduce the risk of basement flooding. • Design requirements for non-potable rainwater harvesting systems are introduced to facilitate the collection and use of rainwater.
