Backflow Prevention Valves

Backflow Prevention on the Upper North Shore and Hornsby Districts

Protecting our local water supply


Prevention Devices

Backflow occurs when water from a property flows backwards into Sydney’s water pipes. This backflow may carry contaminants that can be harmful to people’s health. Backflow prevention devices ensure that the water supply isn’t contaminated from hazards on your property. They stop water in a water pipe from flowing back into the water main.


Thorough Testing
for Your Safety

Only licensed plumbers with a backflow prevention accreditation can inspect, commission and test backflow devices. These licensed professionals are referred to as backflow plumbers, and their accreditation must be issued by a registered training organisation. Once the test has been performed, a backflow plumber must submit the test report using the online lodgement system.
