Backflow Prevention Device Testing
Backflow occurs when contaminated water flows back into the clean water supply, often due to pressure changes. Council regulations require annual backflow testing for many commercial and high-risk sites.
We test and service:
RPZ (Reduced Pressure Zone) Devices
DCV (Double Check Valve) Assemblies
Single Check Valves
Registered Backflow Devices (Sydney Water approved)
Thermostatic Mixing Valve (TMV) Testing
