Testing and reporting

If you have a testable backflow prevention device installed at the water meter you must have the device tested every 12 months and send the results to us. 

Annual testing ensures that the backflow prevention device continues to operate correctly. A defective device can: 

• cause a backflow incident 
• allow water to escape through leaking devices 
• reduce the water pressure to your property. 

To complete the test, you need to engage an accredited backflow prevention plumber. We recommend you use a plumber who can service and repair the device, as well as test the device.

To find a certified backflow plumber, visit the Backflow Prevention Association bpaa.org.au/Testers-VIC.php or Master Plumbers plumber.com.au.

We ask plumbers to complete and return an 'inspection and maintenance report' form as our preferred way of receiving backflow prevention inspection results:
