RPZ FAQs: Testing

What is a compliance test?

This is an on-site procedure to demonstrate a RPZ valve has been installed correctly, and all key components are functioning as required under the RPZ AIM

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.
