Backflow Prevention FAQs

What is backflow prevention and why is it required?

Backflow prevention stops contaminated water flowing back into the drinking water supply. Commercial and industrial sites in WA are required to install devices matched to the property's hazard rating.

Which backflow device does my site need?

The device type depends on the hazard rating — low, medium or high — of the activity on site. We install the full range of testable devices to match the assessed hazard level and the approved design.

How often do backflow devices need testing in WA?

Testable backflow prevention devices generally require testing at least annually by an accredited plumber, with results submitted to the water authority.

Can you install backflow devices on live sites?

Yes. We plan shutdowns and staging with site management so devices can be installed or replaced with minimal interruption to water supply.
