RPZ valve services in Portsmouth
Portsmouth's position as a major naval city and commercial centre on the South Coast means many premises rely on RPZ valves to protect the public water supply. The city centre, waterfront, hospitality venues and commercial buildings across the city are common RPZ test candidates.
Captain Backflow provides a complete RPZ valve service across Portsmouth — from supplying and installing a new valve, to annual testing and ongoing maintenance. As an independent water regulations specialist, we make sure your installation meets Portsmouth Water / Southern Water's requirements and that your records stand up to inspection.
What affects RPZ valve prices in Portsmouth
We keep pricing honest and transparent. The cost of testing or installing an RPZ valve depends on a few straightforward factors.
Number of valves
Most sites have one or two RPZ valves. Testing several on a single visit lowers the cost per valve.
Access and condition
Valves that are easy to reach and in good condition test quickly. Poor access or a valve that needs cleaning takes longer.
Location
Sites across Portsmouth city centre, the waterfront and surrounding Hampshire communities are all within our standard coverage.
Documentation required
Compliant test records for your water supplier and insurer are included with every test we carry out.
No hidden charges
We quote before any work begins. Testing includes compliant documentation, and if a valve fails we explain why and quote for the repair before proceeding. Send us your Portsmouth postcode and the number of valves for an accurate price.
