Specialist Reduced Pressure Zone (RPZ) valve testers
Backflow prevention
RPZ valves are an approved method of preventing backflow and back siphonage for fluid categories up to and including Category 4.
Requiring less pipework modification and needing less space than alternative methods such as break tanks, they are often a preferred method of backflow prevention.
Regular Testing
It is a legal requirement to have RPZ valves tested by an approved tester at least once a year. We are approved to test and install any size RPZ valve attached to any type of installation.
We can supply direct replacements and genuine parts for your current valves.
Notifying your water supplier
Your water supplier requires any RPZ installation to be notified at least 10 working days before work commences. They also require notification of any test or maintenance performed or any change in location or fluid category.
How we work
We install and test all new valves.
We offer yearly maintenance contracts to ensure continued performance.
We also offer a repair service for all types of RPZ valves, or source new ones when needed.
As we have WRAS accreditation for testing any make, model and size of RPZ valve, we will notify your water supplier providing the relevant paperwork and certification as part of our service.
