Backflow

What Is Backflow?

Your plumbing system is designed to keep clean water moving in the correct direction. Backflow occurs when that flow reverses, allowing water from another source to enter the potable water supply.


This can be caused by changes in pressure, such as a drop in the mains water supply or increased pressure within another part of the system. Depending on the property and what is connected to the water supply, the water flowing back may contain contaminants or pollutants.

Backflow prevention devices are designed to stop this from happening and provide an important layer of protection for your water supply.

Plumbing Backflow Preventer Devices & Services

Cramers Plumbing provides a complete range of backflow prevention services for residential, commercial and other Brisbane properties. We can install, test, repair and maintain prevention devices based on the requirements of your plumbing system.

  • Backflow Device Installation

    The right prevention device depends on the type of plumbing system and the potential risk level. Our plumbers can install suitable devices for applications such as:


    • Irrigation systems
    • Dual check valves
    • Reduced pressure zone devices
    • Thermostatic mixing valves

    We’ll assess the application and install the appropriate device to help prevent unwanted water flow back into the potable supply.


  • Backflow Testing & Certification

    Testable backflow prevention devices need to be checked regularly to confirm they are operating correctly. Cramers Plumbing provides backflow testing and certification, including annual testing where required.


    Our plumbers test the device, identify any issues and provide the relevant certification documentation for applicable council and regulatory requirements.

  • Backflow Repairs & Maintenance

    A backflow prevention device must work correctly when needed. If testing identifies a fault or the device shows signs of wear, we can carry out the necessary repairs and maintenance.


    We can also inspect non-testable devices and advise on any work required to keep your backflow protection functioning properly.

  • Emergency Backflow Plumbing

    If you suspect that contaminated or unsuitable water has entered your potable water supply, prompt action is important. Our team can respond to urgent backflow plumbing issues, assess the situation and take appropriate steps to protect your plumbing system.

Why Is Backflow Prevention Important?

Backflow prevention is about protecting the quality of your water supply. Without appropriate protection, water from irrigation systems, equipment, or other sources could potentially enter the clean water network.


A properly selected and maintained prevention device can help:


  • Protect potable water from contamination
  • Reduce the risk associated with cross-connections
  • Keep backflow prevention systems operating correctly
  • Support applicable testing and certification requirements
  • Protect people using the property's water supply

Who May Need Backflow Prevention?

Backflow requirements vary depending on the property's plumbing system and the activities taking place there. Certain connections and equipment can create a higher risk of contamination and may require specific prevention measures.

  • Residential Properties

    Homes with irrigation systems, swimming pools or other plumbing connections may require backflow protection depending on the setup.

  • Commercial Properties

    Businesses can have a range of plumbing fixtures, equipment and water connections that create potential backflow risks. We can assess the system and provide suitable prevention solutions.

  • Hospitality & Food Businesses

    Cafés, restaurants, and other food-related businesses need to take particular care when plumbing systems connect to equipment or processes that could affect the potable water supply. Cramers Plumbing can assist with prevention devices, testing and ongoing maintenance.

  • Irrigation Systems

    Irrigation systems can create a potential cross-connection with the drinking water supply. Appropriate backflow protection can help prevent water from the irrigation system flowing back into the potable network.

  • Industrial & Trade Premises

    Properties using specialised equipment, chemicals or other substances may have specific backflow risks. Our team can assess the plumbing configuration and recommend appropriate protection.

Our Backflow Testing & Certification Process

We keep backflow testing straightforward and work methodically to ensure the device is operating as it should. Steps include: 

1. Device Inspection

We check the backflow prevention device and surrounding plumbing for visible faults, damage or maintenance requirements.

2. Operation Testing

We carry out the required tests to determine whether the device is functioning correctly.

3. Repair Where Needed

If the device doesn't perform as required, we'll identify the problem and complete the necessary repairs or maintenance.
