RPZ FAQs: Testing

When is a compliance test needed?

An on-site compliance test is required following commissioning testing and at set intervals thereafter.

In the case of existing RPZ valves the local water undertaker will advise when compliance testing is required. Those tested annually should not be tested earlier than 30 days prior to the test due date without the agreement of the water undertaker.

Full details are provided in section 5 of the RPZ AIM.
