- About Us
RPZ valves should only be tested by those recognised by the local water undertaker as having sufficient knowledge, experience and skills to enable them to carry out on-site commissioning and/or compliance testing.
Unless recognised by the local water undertaker, on a site specific basis, to be considered as competent a tester must have a recognised qualification in RPZ valve commissioning and/or compliance testing, and should be a member of a recognised RPZ tester approved contractor scheme. They will need to be able to demonstrate to the satisfaction of the local water undertaker, their test equipment is suitably calibrated and they have appropriate liability insurance.
