Installation, commissioning and annual testing of RPZ (reduced pressure zone) backflow prevention valves — carried out by an accredited tester, with certificates and reminders so compliance never lapses.
Annual RPZ valve testing
RPZ valves must be tested at least every 12 months by an accredited tester. We carry out the full test on the relief valve and both check valves, record the results, and issue a certificate for your records and your water supplier.
Where a valve fails, we quote the repair or replacement, carry it out, and retest so you leave the visit compliant.
RPZ installation & commissioning
For fluid category 4 risks — commercial catering, irrigation, dosing systems, certain heating top-ups and industrial processes — we specify and install the correctly sized RPZ valve assembly with the required strainer, isolation, test cocks and tundish discharge.
The installation is commissioned, tested and notified to the water supplier where required.
Servicing, repairs & managed portfolios
We service and repair RPZ valves of all common makes, holding spares for the frequently used models to keep downtime short.
For property managers with multiple valves across a portfolio, we schedule testing, track renewal dates, and send reminders and consolidated certificates.
A complete service, carefully coordinated.
