RPZ FAQs: Testing

Do you need to join an approved contractor RPZ tester scheme?

It is not compulsory for RPZ testers to join an approved contractor scheme. Joining a scheme will however mean that a tester will not be asked to demonstrate:

• They have satisfactorily completed a qualification in RPZ valve commissioning and/or compliance testing recognised by the local water undertaker.
Their test equipment is calibrated by a pressure calibration service accredited by UKAS.
They have appropriate liability insurance.

There may be other advantages to scheme membership, please refer to your local scheme for further information.
