    Backflow Prevention FAQ's

    What is water backflow?

    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.

    What is backflow device testing used for?

    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 02 8859 0801.

    Who can install or test backflow prevention devices?

    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.

    How does The Clean Plumber implement Backflow prevention and testing services?

    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. 

    Contact The Clean Plumber for a quote and expert service.

    Why is regular backflow testing necessary?

    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.

    What is the process for testing a backflow prevention device?

    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.

    How often should a backflow preventer be tested?

    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.

    What are the risks of not installing a backflow prevention device?

    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.

    Which types of properties are required to have backflow prevention devices?

    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.

    What are the signs that backflow might be occurring?

    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.

    What should I do if my backflow prevention device fails the test?

    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.

    If the issue affects your hot water system, we can inspect and repair it to restore safe and reliable operation.

    I used the Clean Plumber and they were honest in their assessment. A previous plumber installed our freestanding bathtub incorrectly and used the incorrect drain connection (for a sink instead of a tub) leading to unbearably slow drainage. I hired two other plumbers who couldn’t diagnose the problem correctly but the Clean Plumber came and identified the issue and re-installed the tub with correct parts. All along the process they were upfront as to how much it would cost to do the work based on issues found. They were pleasant to deal with and thoroughly explained how they were going to fix it. I would definitely use them again.

    I recently had the pleasure of having Tanaka from The Clean Plumber handle a plumbing issue at my home, and I couldn't be happier with the service. From start to finish, Tanaka was the epitome of professionalism. He arrived on time, which I greatly appreciated, and even wore shoe covers to ensure my home stayed spotless—such a thoughtful touch!Tanaka was incredibly polite and took the time to clearly explain the work that needed to be done, outlining all the options available with transparent and very reasonable pricing. This made it easy for me to make an informed decision without feeling pressured. His work was efficient, thorough, and left everything cleaner than when he arrived.Not only did he solve the plumbing issue flawlessly, but he was also genuinely pleasant to have around, making the whole experience stress-free. I will absolutely be using The Clean Plumber again, and I highly recommend Tanaka to anyone in need of a reliable, skilled, and courteous plumber.

    Recently called the clean plumber for an urgent plumbing issue. I have never called them before but after jayden arrived to my house and completed the work I’ll never call anyone else. Jayden was on time, had great communication, explained everything he was doing to me and how things work, his work was precise and to a high standard and left the work area spotless. I will definitely be asking for Jayden again next time I need a plumber.

    My in-laws were after a reliable plumber but didn’t know anyone reputable. I did a google search for them and took a few quotes. Although The Clean Plumber wasn’t the cheapest, their quote was still very reasonable and they were by far the most professional to deal with. Happy with the job and glad we took the plunge. Workmanship 5 stars, Service 5 stars and reliability 5 stars. Job well done!!
