Testing, Maintenance and Compliance Support for Backflow Devices
Backflow prevention devices help protect the drinking water supply by preventing potentially contaminated water from flowing back into the mains. If your property has a testable backflow prevention device, regular testing may be required to confirm it is operating correctly and meets local compliance requirements.
AR Plumbing Service provides backflow prevention testing in Pottsville, across the Tweed Coast and surrounding Northern Rivers communities, with services also available in parts of Byron Shire.
We can test applicable devices, identify maintenance or repair requirements and complete the relevant documentation for submission to the appropriate local authority.
What Backflow Prevention Testing Involves
Reduced pressure zone (RPZ) devices
Tested using a differential pressure gauge across the two check valves and the relief valve. The device must hold specified pressure differentials to pass.
Double check valve assemblies (DCVA)
Each check valve is tested independently to confirm it seals correctly under back-pressure conditions.
Testable double check valves
Smaller devices on residential properties are tested using the same pressure differential method suited to the valve size.
Who Needs Backflow Prevention Testing
Backflow prevention devices are generally required where there is a risk that contaminated water could flow back into the public water supply. Testing may be required for:
- Commercial properties — cafes, restaurants, medical practices, dental surgeries, hairdressers, car washes, and industrial sites.
- Properties with irrigation systems — underground irrigation connected to the mains supply requires a testable backflow device.
- Properties with fire services — fire hydrant and sprinkler systems connected to the water main typically require RPZ protection.
- Swimming pools and spa connections — where the pool fill line is connected to the mains without an air gap.
- Residential properties with specific installations — solar hot water systems with certain valve configurations, rainwater tank mains-connected top-up systems, and garden chemical injector systems.
Backflow testing requirements can vary depending on the property's location, hazard classification and the type of device installed. Tweed Shire Council maintains records of testable backflow prevention devices, and Byron Shire Council has its own requirements for applicable properties and devices.

Frequently Asked Questions
Testing frequency depends on the type of device installed, the property's hazard classification and the requirements set by the relevant authority. Many testable devices require regular testing, with annual testing common for many installations.
If a device does not pass testing, the plumber can identify the issue and recommend the appropriate repair or replacement option. Where practical, repairs may be completed and the device retested to confirm it is operating correctly.
Not every residential property requires a backflow prevention device. Requirements depend on the plumbing installation, potential risks and whether there are specific connections such as irrigation systems, rainwater systems or other higher-risk applications. A plumber can assess your property and advise whether testing or installation may be required.
Testing documentation is completed as required for the relevant installation and authority requirements. A copy of the documentation can also be provided for property records.
