Instantly switch off the water supply to part of a building with this 15 mm Flume full bore isolating valve CP. Once installed, you can speed through your plumbing jobs, as there's no need to drain your water tank in order to halt the entire supply at the mains. You'll find this handy component in residential and commercial settings such as holiday homes, offices and industrial units. It's easy to install whether you're a DIY novice or a professional plumber.
This is a Water Regulations Advisory Scheme-compliant isolating valve, so you are legally permitted to use it as part of a plumbing system that carries water away from the British mains. It's a full bore valve, which means it has a larger diameter and inner core to allow water to freely flow through its centre.
