Reduced pressure zone valves are backflow protection devices and need to be checked on an annual basis to ensure continual capability of backflow protection. All commissioning and testing of these valves needs to be carried out in accordance with the water suppliers approved installation method AIM-08-01 and must only be carried out by approved test engineers who have completed an RPZ course endorsed by WRAS.
Our engineers have completed a WRAS endorsed course and are qualified to carry out the testing and commissioning of RPZ installations.
