RPZ Valves
RPZ Valve
An RPZ Valve is considered suitable for high hazard applications, that is, where the consequence of backflow into the water supply would cause significant harm. They are considered suitable because they prevent both backflow and back-siphonage, because of a redundant design (even with two check valves broken the device still provides protection), and because they are testable to verify correct operation.

We are a WRAS listed RPZ valve tester and we work primarily the Yorkshire and Humberside Areas. But have facilities to work further.
