Professional Plumbing Services You Can Trust
Backflow prevention protects your drinking water supply from contamination by preventing water from flowing backwards through the system. This can occur when mains pressure drops (e.g., during a water main break or high-demand period), potentially drawing contaminated water from irrigation systems, pools, hot water units, and other sources back into the drinking water supply. Tradetek Solutions installs, tests, and maintains all types of backflow prevention devices as required by Sydney Water and other NSW water authorities.
We are accredited backflow prevention specialists, qualified to install, commission, test, and maintain all classes of backflow devices. We understand the regulatory requirements — many properties are required by their water authority to have testable backflow devices that must be inspected annually. We manage the entire process from initial risk assessment through device selection, installation, testing, and annual compliance reporting to your water authority.
Common Plumbing Issues We Solve
1Missing Backflow Prevention
Many properties, especially those with irrigation systems, swimming pools, fire services, or commercial processes, are required to have backflow prevention but don't. Water authorities are increasingly auditing compliance — we install devices to bring your property up to standard.
2Failed Annual Testing
Testable backflow devices (RPZ valves, double check valves) must pass annual testing. Internal seals and springs wear over time, causing devices to fail testing. We carry repair kits to service and re-test failed devices on the spot.
3Incorrect Device for Hazard Level
The type of backflow device required depends on the hazard rating — high hazard (e.g., chemical processes) requires RPZ valves, while medium hazard (e.g., irrigation) requires double check valves. We assess your hazard level and install the correct device.
4Reduced Water Pressure After Installation
Some backflow devices can cause a noticeable pressure drop, especially if undersized. We select appropriately sized devices and installation configurations to minimise pressure loss while maintaining full backflow protection.

Frequently Asked Questions
Common questions about our plumbing services answered by our experts
Does my property need a backflow prevention device?
Does my property need a backflow prevention device?
Properties with irrigation systems, fire hose reels, swimming pool auto-fill, cooling towers, commercial kitchens, or any connection that could contaminate the water supply typically require backflow prevention. Your water authority can issue a requirement notice, or we can conduct a risk assessment for you.
How often does a backflow device need testing?
How often does a backflow device need testing?
Testable backflow devices (RPZ valves and double check valves) must be tested annually by an accredited tester and results submitted to your water authority. We manage the entire process including scheduling, testing, repairs, and lodgement.
What is the difference between RPZ and double check valves?
What is the difference between RPZ and double check valves?
RPZ (Reduced Pressure Zone) valves protect against high-hazard contamination risks and discharge water if the device detects backflow. Double check valves protect against medium-hazard risks and are simpler, smaller, and less expensive. The required type depends on your assessed hazard level.
What happens if I don't comply with backflow requirements?
What happens if I don't comply with backflow requirements?
Water authorities can issue penalty notices and, in serious cases, restrict or disconnect your water supply for non-compliance. Annual testing and compliance reporting is the property owner's legal responsibility.
Can you handle the water authority paperwork?
Can you handle the water authority paperwork?
Yes, we submit all test results and compliance reports directly to Sydney Water and other NSW water authorities on your behalf. We also maintain records and send you reminders when your annual test is due.
