Backflow Testing and Maintenance Services in Adelaide and Adelaide Hills
Protect Your Water Supply with Certified Backflow Prevention
Backflow prevention is a critical but often overlooked aspect of plumbing safety. At Flowtec, we provide expert backflow testing, maintenance, and certification throughout Adelaide and the Adelaide Hills, ensuring your water supply remains clean and uncontaminated while helping you meet regulatory compliance requirements.
What Is Backflow & Why Does It Matter?
Backflow occurs when water flows in the opposite direction than intended in your plumbing system, potentially allowing contaminated water to enter your clean water supply.
Backflow prevention devices (BFDs) are designed to stop this from happening, but they require regular testing and maintenance to function properly and remain compliant with state regulations.
Our Backflow Testing & Maintenance Services
Flowtec’s expert technicians provide comprehensive testing, servicing, and repairs for all types of backflow prevention devices to ensure optimal performance and compliance.
Thorough Backflow Device Testing
Our licensed plumbers use calibrated test equipment to verify your backflow devices are functioning correctly and provide official documentation for compliance. We test:
- Reduced Pressure Zone (RPZ) Valves – High-hazard protection devices requiring annual testing.
- Double Check Valves – Medium-hazard protection devices commonly used in residential and commercial properties.
- Dual Check Valves – Entry-level protection often installed at property boundaries.
We ensure your backflow prevention system meets all legal requirements while keeping your water supply safe and reliable.
Backflow Device Maintenance & Repairs
In addition to testing, we offer preventative maintenance, repairs, and system upgrades to keep your backflow prevention devices in top condition. Our services include:
- Preventative Maintenance – Cleaning, inspecting, and adjusting devices for continued reliable operation.
- Repairs to Existing Devices – Fixing leaks, replacing worn components, and resolving operational issues.
- Installation of New Devices – Upgrading outdated or non-compliant systems with certified replacements.
- System Upgrades – Assessing your risk level and recommending the appropriate backflow prevention solutions.
Whether you need a single device tested or a full system overhaul, Flowtec can guarantee your backflow prevention system is fully functional and compliant.

How often do backflow prevention devices need to be tested?
In South Australia, Reduced Pressure Zone (RPZ) devices must be tested annually as a minimum requirement. Double check valves typically require annual testing as well, though requirements can vary based on the specific application and level of hazard. Dual check valves may have different testing schedules. We can advise on the specific requirements for your property based on device type, installation location, and local regulations.
What happens if my backflow device fails the test?
If your device fails testing, we’ll explain exactly what’s wrong and provide options for repairs or replacement. Minor issues can often be fixed on the spot during the testing appointment. If replacement is necessary, we can usually schedule this promptly to minimize your period of non-compliance. We’ll provide temporary solutions if appropriate and advise on any notifications required to regulatory authorities.
Do residential properties require backflow prevention?
Many residential properties in Adelaide now have backflow prevention devices installed, particularly newer homes or properties with irrigation systems, swimming pools, or other features that present potential cross-connection hazards. While testing requirements for standard residential properties may be less stringent than commercial buildings, maintaining functional backflow prevention is still important for protecting your household water supply. We can assess your property and advise on appropriate backflow prevention needs.
