Backflow Prevention FAQ’s
Water typically flows into your property at a steady pressure, ensuring consistent tap performance. However, reduced pressure can cause backflow, where contaminated water is pulled back into the supply. Backflow may occur if a nearby pipe bursts, water is pumped for firefighting, you use water at higher pressure, or high demand lowers your property’s pressure.
Most residential properties are low-risk and don’t require special testing. However, high and medium-risk properties need registered backflow prevention devices, air gaps, break tanks, and fire service valves tested annually by a licensed plumber.
For backflow plumbing services, call our team at 0488 854 186.
Only licensed plumbers with backflow prevention accreditation can inspect, commission, and test medium and high-hazard backflow devices. After installation, only these accredited plumbers can perform tests and submit the test reports.
As a property owner, you must maintain backflow prevention systems. Trust our accredited plumbers to install customised devices, provide compliance certificates, and conduct annual testing with results submitted to Sydney Water.

Regular backflow testing is essential for health and safety, as it prevents contaminated water from entering your water supply, which could lead to serious illness. Testing is required after installation, repairs, or relocation of backflow devices, and at least once a year for ongoing protection. Our emergency plumbing services ensure that any urgent issues are resolved quickly to maintain the safety of your water supply.
A professional plumber tests backflow prevention devices by operating valves to identify any issues. After the inspection, a report detailing the device’s condition is prepared and submitted to the relevant water authority.
Backflow valves need to be inspected annually. Businesses are responsible for both installing and maintaining their systems. Failing to do so could result in contaminated drinking water, exposing them to significant liability risks. Without a backflow prevention device, contaminated water can enter the clean supply, posing health risks and potential legal liabilities.

Without a backflow prevention device, contaminated water can enter the clean water supply, posing health hazards and potential legal liabilities for businesses. It’s crucial to have a backflow device installed and maintained to protect against contamination.
Properties that use irrigation systems, hazardous materials, or are otherwise at risk of contamination are required to have backflow prevention devices installed. High-risk facilities, such as hospitals and food processing plants, are also required to have these devices. For more detailed information on backflow prevention, visit our blog.
Signs of backflow include discoloured, foul-smelling, or odd-tasting water, as well as a sudden drop in water pressure. If you notice any of these signs, contact our professional plumbers immediately to assess and resolve the issue. Our leak detection services can help identify and resolve any underlying issues before they worsen.
If your device fails the test, it’s important to contact our professional plumbers immediately for repairs or replacement. Addressing the issue promptly will help prevent contamination and ensure compliance with health and safety standards.
