Get Backflow Test Report

The principal types of mechanical backflow preventer are testable devices such as the reduced-pressure principle assembly, the pressure vacuum breaker assembly, and the double check valve assembly.

For the purposes of installing and repairing backflow preventers a person is required by the Trades Qualification Act of Ontario to be a journeyman plumber or a registered apprentice working under the direction of a journeyman plumber.

Check valves use a hinged plug that allows water to pass through the pipeline but blocks it from coming back. Backflow preventers, on the other hand, apply an increased amount of pressure on a pipe to ensure the water can only flow one way.

Backflow can pose a public health risk if pollutants or contaminants such as chemicals enter the drinking water supply from your property. A backflow prevention device allows water to enter the property through the water meter, and prevents water from flowing back into the water supply network.

Installation of backflow preventers is required under Section 7 of the Ontario Building Code and the Ministry of Environment, Conservation and Parks expects the Town to implement a backflow prevention program. This is considered to be a necessary industry best practice.

Backflow prevention systems are devices installed onto a pipe that only allow water to flow in one direction. Think of it as a one-way gate that allows water from the city's public water supply to flow into your home's piping but stops water if and when it ever tries to flow backwards into the main water supply.

The Manager shall inspect and approve all installations of the required backflow prevention devices. The costs for purchasing, installing, and maintaining a backflow prevention device shall be the responsibility and sole expense of the consumer. The consumer shall the backflow prevention device.

Reduced Pressure Principle Backflow Prevention Assembly (RP) An RP consists of inlet and outlet shut-off valves, four properly located test cocks, a first and second check valve component, and a relief valve component.
