RPZ FAQs: Testing
What is a valid commissioning/compliance test report?
Before an RPZ valve can be brought into service the local water undertaker will require all newly installed RPZ valves, including replacement RPZ valves, satisfy both on-site commissioning and compliance testing, plus where required flushing and disinfection.
To be considered by the local water undertaker as being valid a test report must be:
- Completed, signed and dated by a RPZ tester they consider to be competent using calibrated suitable test equipment
- Submitted in an acceptable format
- Provide the minimum information required
- Be received by the local water undertaker within 10 working days of test – unless the valve fails test in which case specific reporting requirements apply.
For further information please refer to the RPZ AIM.
