Where to Install Shut-Off Valves

Fitting isolation valves at key points in your water system makes future maintenance far easier. Typical positions include immediately after the pump, on the feed to the water heater, and on each supply branch to individual tap or shower circuits. Once installed, you can service any section without draining the whole system.

Installation

Fit inline in the 12mm supply pipework at the chosen isolation point. Ensure all connections are secure before restoring system pressure. Test for leaks before closing up any panels.
