Choosing the Correct Backflow Prevention Device
Not all backflow prevention devices provide the same level of protection. The correct device depends on factors such as:
- The type of property.
- The potential contamination risk.
- The plumbing system design.
- The water authority requirements.
- The type of hazard being protected against.
- The required flow rates and pressure conditions
Our licensed backflow plumbers assess your requirements and recommend the appropriate backflow prevention solution to help ensure your property remains compliant.
Common devices we install include:
- Reduced Pressure Zone (RPZ) valves
- Double Check Valves (DCV)
- Double Check Detector Assemblies
- Fire service backflow prevention devices
- High hazard backflow prevention assemblies
- Commercial and industrial backflow systems
Professional Backflow Installation Process
A correctly installed backflow device is essential for reliable operation and future maintenance.
Our installation process includes:
Site Assessment
We inspect your property and existing plumbing system to determine the most suitable location and device type.
Device Selection
We help select the appropriate backflow prevention device based on your property’s requirements and applicable water authority conditions.
Professional Plumbing Installation
Our licensed plumbers install backflow prevention devices in accordance with manufacturer requirements, plumbing regulations and industry standards.
Testing and Commissioning
Following installation, the device is tested and commissioned to confirm correct operation.
Certification and Documentation
All required documentation is completed, and certificates are lodged with the relevant water authority where required.
Why Correct Installation Matters
Incorrectly installed backflow prevention devices can create problems including:
- Reduced flow rates
- Pressure drop complications
- Difficult future testing
- Increased maintenance costs
- Reduced protection of the drinking water supply
- Compliance issues with water authorities
A backflow device must be installed with future servicing and testing in mind. Our plumbers consider accessibility, isolation requirements and ongoing maintenance when completing every installation.
Our team works with:
- Builders
- Hydraulic consultants
- Developers
- Facility managers
- Property owners
- Strata managers
- Water Authorities and Councils
- Other Plumbing Contractors
We can assist with:
- New backflow device installations

The Specialist Difference
Common installation issues we regularly encounter
- Devices installed too close to walls, making future testing and servicing difficult.
- Incorrect installation height above finished ground level.
- No drainage provided for RPZ relief valves.
- Missing downstream isolation valve before the H-pattern test assembly.
- Backflow prevention devices installed without considering future maintenance access.
A compliant installation is about more than simply fitting a backflow prevention device. Our licensed backflow plumbers consider accessibility, drainage, isolation valves and future servicing requirements from the outset, helping ensure every installation is practical to maintain and compliant with Australian Standards and water authority requirements.
Backflow Device Replacement and Upgrades
Sometimes an existing backflow device can no longer be repaired and replacement is the most practical solution.
Our licensed backflow plumbers can assess your existing device and recommend replacement options where required.
Replacement may be recommended when:
- The device is beyond economical repair.
- Spare parts are no longer available.
- The device no longer meets current requirements.
- The installation requires upgrading.
- The property use has changed and a different level of protection is required.
We provide clear advice and practical solutions before any replacement work proceeds
