RPZ FAQs: Testing

What happens if an RPZ valve fails compliance testing?

If an RPZ valve fails compliance testing the next steps depend on whether the valve can be repaired and retested and how quickly this can be done.

If it is repaired and satisfactorily retested immediately then it may be returned to service. The test failure and successful retest, together with details of the repairs undertaken and any suspected contributing factors to the failure, will be reported by the RPZ tester to the water undertaker within 24 hours.

If the RPZ valve cannot be repaired and satisfactorily retested immediately, then the tester will notify the water undertaker straight away. The water undertaker will confirm what action is to be taken. The RPZ tester will notify you what action is required.
