3 This information has no legal status and cannot be used as an official interpretation of the various bylaws, codes and regulations currently in effect. The Town of High River accepts no responsibility to persons relying solely on this information.

This information is only a guide and, as a homeowner, you must have a basic knowledge of plumbing systems to take on any installations or renovations. Other methods of installation may be acceptable; however, all installations must meet the most current requirements of the National Plumbing Code of Canada.

Permits and inspections The Province of Alberta’s Safety Codes Act Permit Regulation requires a plumbing permit to install, alter or add to a plumbing system. An active plumbing permit is required before any inspections can be booked. All plumbing installations and renovations must have a Town of High River plumbing and gas safety codes officer perform inspections as outlined in the Town’s Quality Management Plan (QMP).

Booking an inspection

• Call at least two working days in advance. • Access must be arranged by homeowner and someone 18 years or older must be present. • Appointments are not possible; inspections are available Monday & Wednesday. • Plumbing inspections are separate from the building and electrical permit inspections.

Rough Inspection

• All plumbing drainage and venting must be installed and complete. • Waterlines must be installed and connected to the rest of the water distribution system. • All drains, vents and waterlines must be properly supported. • The bathtub/shower valve must be installed.

Final Inspection • All fixtures and equipment must be installed and ready for use. • Temperature of water at the bathtub and shower must not exceed 49 degrees Celsius. • All piping designed for future fixtures must be sealed with an approved plug or cap. • Toilets must be provided with a shut off valve.

Faucets, shower heads and toilets are just a few examples of fixtures available in low water use models.
