Isolate and regulate the flow to any water fitting. The Isolation Valve becomes important when you have to work on a particular section of the water system and do not wish to stop the water supply of the entire system. The Isolation Valve is available here in 15mm size and has a chrome finish. It can be installed to create separate water circuits within the system, and ensure that you can easily make repairs or replace taps and water using appliances. Installed easily thanks to the 15mm compression fitting – with no need for heat or solder.
