What Is Backflow?
Backflow is the unwanted reversal of water through a plumbing system. Under normal conditions, water should move from the supply into the property. A change in pressure or an unprotected connection can allow water to move in the opposite direction.
If the downstream water has been exposed to chemicals, waste, irrigation systems, equipment or another contamination source, backflow can create a risk to the clean water supply. A backflow prevention device is selected and installed to manage the relevant level of risk.
Backflow requirements depend on the property, connected equipment, water authority conditions and the applicable plumbing requirements. Customers should rely on licensed assessment rather than assuming every property needs the same device or testing arrangement.
Our Backflow Services
Backflow Prevention Device Testing
We test suitable backflow prevention devices to assess whether they are operating as required at the time of the service. The process may include:
- Identifying the device and installation
- Inspecting accessible components
- Conducting the applicable test
- Recording the result
- Advising whether servicing or further work is required
- Providing relevant service documentation
Backflow Device Servicing
Where a device does not perform as expected, servicing may be possible depending on the type, condition and availability of suitable components.
Backflow Device Installation
We install backflow prevention devices for suitable residential, commercial and project applications. The device selection and installation position should reflect the identified hazard and relevant requirements.
Replacement and Upgrade
A device may need replacement where it is damaged, heavily deteriorated, unsuitable for the application or unable to be restored through servicing.
Backflow Advice for New Projects
Backflow requirements should be considered during design and installation planning. Early review can help avoid access, location and coordination problems later in the project.
Properties and Systems That May Require Backflow Protection
Contact a plumber when you notice a change that may indicate a fault rather than waiting for the problem to become more disruptive.
Backflow protection may be relevant to:
- Commercial properties
- Industrial and warehouse facilities
- Mining and regional sites
- Strata and common-property systems
- Irrigation systems
- Properties with fire services or specialised equipment
- Sites using chemicals or non-potable water
- Residential properties with particular cross-connection risks
- New developments and plumbing upgrades
This list is general. The actual requirement should be confirmed for the specific property and system.
Why Backflow Testing Matters
A backflow device is a safety component. Its presence alone does not confirm that it is operating correctly or remains suitable for the installation.
Testing and professional assessment can help:
- Confirm device operation at the time of testing
- Identify faults or deterioration
- Support property and asset records
- Inform servicing or replacement decisions
- Protect the integrity of the water system
- Support relevant authority or site requirements
Do not publish a fixed testing frequency across every device and property unless it has been confirmed against the relevant authority and device requirements.
What Happens During a Backflow Service?
Confirm the Property and Device
Provide the address, device information and any previous test or authority documentation available.
Access and Inspection
The plumber locates the device, reviews the installation and confirms that the required access and isolation conditions are available.
Testing
The applicable test is completed using suitable equipment and the result is recorded.
Recommendation
If the device requires servicing, repair, replacement or further investigation, the recommendation is explained.
Documentation
Relevant service information is provided and any required submission process should be confirmed for the specific property or authority.
