RPZ FAQs: General

Where can an RPZ valve be installed as point of use backflow protection?

If a system in your premises has been categorised as fluid category 4 or less by your water undertaker, then an RPZ valve may be an appropriate form of point of use backflow protection. For further information consult the local water undertaker.

Please note: to show they are functioning satisfactorily all RPZ valves are required to be regularly tested by a competent RPZ tester. Test intervals are set by the local water undertaker. Whilst test intervals may vary, they will be at least annually.
