Types of backflow prevention devices

In Australia, several types of valves and devices are used to prevent contaminated water from flowing back into the main supply. At Complete Backflow Testing, we work with all major types of approved backflow prevention systems, ensuring each is correctly installed, maintained, and tested for compliance.

The most common types include:

1. Pressure Vacuum Breaker (PVB) – Prevents backflow in systems where back pressure isn’t a concern.
2. Double Check Valve (DCV) – Offers reliable protection for low to medium hazard applications.
3. Reduced Pressure Zone Device (RPZD) – Provides the highest level of protection against backflow in high-risk areas.
4. Single Check Valve Testable (SCVT) – A testable option suitable for low-risk situations.
5. Single Check Detector Assembly (SCDAT) – Commonly used in fire services to monitor unauthorised water use.
6. Registered Break Tank (RBT) and Registered Air Gap (RAG) – Physical separation methods that eliminate the risk of backflow.
