A ‘testable backflow prevention device’ is installed in the water supply pipes to stop contaminants from getting into the drinking water.
Properties that have ‘high hazard’ installations need a testable backflow prevention device installed. A Certificate of Likely Compliance and Plumbing Permit must be issued by Council before they are installed.
Owners of these devices are responsible for having each one tested by a plumber who is licensed to test the devices every 12 months.
When they pass the test the plumber will fill out a test report form and a copy of this must be sent to us so we know that the test has been done and that the device is working properly

We keep a register of testable backflow prevention devices that are located within a property, and an annual reminder and an invoice is sent to owners.
