A ‘testable backflow prevention device’ is installed in the water supply pipes of a property to prevent contaminants being introduced into the drinking water.
Properties that have water installations that are considered to be high hazard installations require a testable backflow prevention device to be 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 at least every 12 months.
When they pass the test the plumber will fill out a test report form (Testable Backflow Prevention Device Test Certificate). A copy of this must be sent to Council verifying that the test has been done and that the device is working as designed.
The Council is required to 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 in order to maintain this register.
