Professional RPZ valve testing and backflow prevention for commercial properties in Cardiff and the surrounding Wales area.

RPZ testing services in Cardiff

Cardiff's growing commercial and leisure sectors, from Cardiff Bay to the city centre, require reliable RPZ compliance for shared and process supplies.

Bay‑side hospitality venues frequently require RPZ valve testing.

We test reduced pressure zone valves to confirm both check valves and the relief valve are operating within the required parameters, and we provide compliant documentation for your records. Testing is generally carried out annually, though the exact obligation depends on the installation, your water supplier and the relevant requirements that apply.
