Short Backflow Testing FAQs

What is backflow testing for?

Backflow testing checks your backflow prevention devices annually (as mandated by law) to ensure dirty or contaminated water does not flow back into Sydney Water's supply. This problem can occur if the main system loses pressure for some reason. The testing can only be done by an accredited backflow plumber.

What is involved in backflow testing?

The testing process involves using a flow testing kit. Accredited plumbers will close valves and checking for changes in gauge movement, water leaks and other signs. The flow testing kit is tested and calibrated by an approved authority annually.

Is backflow testing necessary?

By law, a boundary backflow prevention device must be checked annually by an accredited and licensed plumber in NSW.

How much does it cost to have a backflow preventer tested?

Backflow testing costs $120 for the first valve, and $80 for each additional valve. Yearly testing is mandatory, and it ensures that your system blocks the backflow into Sydney Water. A report is submitted to Sydney Water for registration, and some plumbers provide yearly reminders as well.

How often is backflow testing required?

In NSW backflow prevention devices are required to be tested annually (and upon installation or repair).
