Contaminants used in some applications can pose a serious risk to the safety of the fresh water supply in your area. This can potentially allow contaminated water containing such as hazardous chemicals, bacteria and debris to flow back up into the water service.

A licenced and accredited backflow prevention plumber is required to test, inspect and commission the backflow devices. Your backflow plumber will submit the completed test report to Sydney Water (or relevant water authority or council) on your behalf.

Backflow testing ensures the device is working to protect the drinking water in your area. During a backflow test, your plumber will turn off the downstream shut-off valve, wait a few minutes and test the pressure in the system using a special backflow testing kit. The test is carried out to ensure the pressure is as it should be and the device is functioning.
