Backflow Prevention

Backflow is a reversal of the normal direction of water flow in a water supply plumbing system. It occurs when the water delivery main is at a lower pressure than the internal plumbing system (back siphonage). Back siphonage can occur when there is a burst or ruptured water main, or due to excessive demand during fire-fighting operations or other periods of high demand.

Backflow can also occur if a water pump, such as a bore pump, is cross-connected to the internal water plumbing system, and is pumping bore water at a higher pressure than the water mains pressure (back pressure).

If a property’s drinking water supply is inadvertently connected with a source of pollution, either through a cross-connection or simply a hose submerged in a container of liquid, then these pollutants could enter the water supply when there is an overpressure on the private property side or a sudden drop in water mains pressure.

Why install a Backflow Prevention Device?

The community has a right to protection from contaminated water as the result of a backflow incident. Contaminated water can cause health problems or death and because of this, there are obligations under legislation to install a backflow prevention device:

  • Water Services Act 2012
  • Water Services Regulations 2013.

Who can install a Backflow Prevention Device?

Only licensed plumbing contractors who are certified may install backflow prevention devices such as ourselves – Plumbers and Gasfitters Bunbury

Spoke to the owner Luke in the morning about a leak in the roof space. He sent one of his workers around the same day to repair and install a new copper line and garden tap. Jeremy was polite and did a professional job. Thanks guys.
