JG 12mm Shut-off Valve

Every plumbing system is installed with shut-off valves. These highly important valves are useful during water leaks and pipe busts as they can shut-off the flow of water to the pipes, thus preventing a bigger mess. Over time your shut-off valves may become rusted or simply impossible to turn. If this is the case for you, John Guest manufactures 12mm plastic shut-off valves that are great for use in caravans.
