Backflow testing in Queensland: what, why and how often

Backflow prevention keeps contaminated water from flowing back into the drinking supply. In Queensland, testable backflow devices must be tested every year, and it is the property owner who is responsible for keeping it current.

What backflow prevention is

A backflow prevention device stops water from a property (for example from irrigation, a fire service or a commercial process) flowing back into the public drinking water. Properties with a higher contamination risk are required to have testable devices fitted.

How often it must be tested

Testable devices must be inspected and tested every twelve months by a licensed backflow tester, with the results lodged to the local water service provider (such as Urban Utilities in Brisbane). Arranging it is the owner responsibility.

What happens if it lapses

Letting testing lapse can lead to non-compliance notices and fines from the water authority. For sites with several devices, scheduling the testing so nothing slips is the easy way to stay compliant.

Common questions

Who needs a backflow device tested?

Any property with a registered testable backflow prevention device, common on commercial premises, body corporates, and homes with things like irrigation or fire services. If you are unsure, we can check.

Do you handle the paperwork with the water authority?

Yes. We test the device, lodge the results with the relevant water service provider, and give you a copy for your records.
