Backflow Prevention FAQs

Backflow in plumbing occurs when the water flow reverses, allowing contaminated or non-potable water to flow back into the clean water supply. This can happen due to changes in water pressure caused by events like a broken water main, high system demand, or improper plumbing installations. Backflow can pose serious health risks, as it may allow contaminants like chemicals, bacteria, or waste to enter the drinking water supply.

In Queensland, backflow prevention devices are mandatory in properties with a risk of contamination. Local councils maintain a register of testable backflow devices, and property owners are responsible for ensuring that only licensed plumbers inspect these devices annually to comply with safety standards and regulations​.

Backflow in a plumbing system occurs when the flow of water reverses, potentially allowing contaminated water to flow back into the clean water. The two main causes of backflow are backpressure and backsiphonage.

  • Backpressure happens when the pressure in a system exceeds the water supply pressure. This could occur if a pump, heating system, or other equipment generates more pressure than the supply, forcing water to flow in the wrong direction.
  • Backsiphonage occurs when there is a sudden drop in water pressure, creating a vacuum effect. This can be caused by events like a broken water main, firefighting operations, or high demand for water. The pressure drop allows dirty water from appliances, pools, or irrigation systems to be drawn back into the clean water supply.

Both conditions can lead to serious health hazards if not properly controlled. Installing backflow prevention devices and maintaining regular system checks are key to avoiding these risks​.

If you smell a foul odour, notice inconsistent water levels, observe colour changes to brown, yellow, or pink, or find pooling water in your garden, you may have a backflow issue that needs addressing by a backflow plumber.

Backflow in plumbing can be stopped using specific prevention measures designed to ensure water only flows in one direction. The most common methods include:

  1. Backflow prevention devices: Devices such as check valves and reduced pressure zone (RPZ) assemblies are installed at key points in the system. These devices ensure that water cannot flow backward into the clean water supply by using a series of valves that automatically close when backflow is detected. These are highly effective and commonly used in both residential and commercial properties.
  2. Air gaps: A simple but effective method where a physical gap is maintained between the water outlet and any potential hazards. For example, a faucet positioned well above the sink’s highest water level prevents water from siphoning back into the supply.
  3. Barometric loops: These specialised loops in the piping system prevent siphoning by maintaining a certain height, making it difficult for water to flow backward due to pressure changes.

By installing the right devices and regularly maintaining them, you can effectively prevent backflow and ensure your water supply remains clean and safe.

The purpose of a backflow test is to ensure that backflow prevention devices are working properly to protect water from contamination. This testing verifies that water is only flowing in the correct direction and that there is no risk of contaminated water entering the potable water system.

Regular testing is essential to maintaining water safety and ensuring compliance with local health regulations.

If you fail a backflow test in Queensland, you are legally required to repair or replace the faulty device to comply with regulations. Backflow prevention devices must function properly to protect the water supply. If the issue is not addressed immediately, you risk fines, water service disruptions, or legal penalties.

According to the Gold Coast City Council, failed devices must be repaired or replaced immediately, and a new test must be conducted. Property owners are responsible for ensuring this is done in compliance with local regulations​.

Preventing the backflow of water involves using various methods to ensure that water only flows in the intended direction, keeping contaminants out of your water. Some of the most effective methods include:

  1. Backflow prevention devices: Installing devices like check valves, reduced pressure zone (RPZ) assemblies, or vacuum breakers helps ensure that water can only flow in one direction. These devices automatically close when backflow conditions are detected, avoiding water contamination.
  2. Air gaps: This is a simple but effective method of creating a physical gap between a water outlet and the source of contamination. It is often seen in taps and sinks, where the faucet is positioned higher than the sink’s overflow level.
  3. Regular maintenance: Maintaining your plumbing system, including checking for leaks, corrosion, and pressure imbalances, helps prevent backflow. Annual inspections by Local Plumbing & Gas Co. can detect potential issues before they become serious.
  4. Proper drainage systems: Ensuring your drains are clear and functional can help avoid pressure buildups leading to backflow. Regular cleaning and proper drainage system design are key preventive measures.

At Local Plumbing & Gas Co., we provide comprehensive backflow prevention services, including TMV installation and testing and replacement and repair of backflow prevention devices.

Installing a backflow valve is a step-by-step process. Here’s how it’s typically done:

  1. Shut off the water: Before starting the installation, the main water valve to the area where the valve will be installed is turned off.
  2. Cut the pipe: Using a pipe cutter or hacksaw, the installer cuts the water pipe at the desired location for the backflow valve. The cut must be clean and perpendicular to the pipe to ensure a proper fit.
  3. Apply Teflon tape and pipe dope: To ensure a leak-free connection, Teflon tape is wrapped around the male threads of the valve, and pipe dope (thread sealant) is applied for extra security.
  4. Install the backflow prevention device: The valve is then screwed into place, first hand-tightened, followed by using a pipe wrench to secure it snugly. This ensures a proper seal and prevents any water leakage.
  5. Reconnect the pipe: The other side of the pipe is then connected to the backflow preventer, using the same process of applying Teflon tape and pipe dope before tightening the connection.
  6. Turn the water back on: Once the installation is complete, water is turned back on, and the system is checked for any leaks. The installer will also test the valve to ensure it functions correctly​

Our fully licensed plumbers handle every step of backflow valve installation, ensuring compliance with local regulations and industry standards.
