The Oracstar Surestop is a unique and innovative stopcock, focused on protecting properties from the risk of water damage caused by leaks. With a simple flick of a switch, Surestop will completely STOP the water supply, without the use of batteries or electrics. Quick and easy to install and use, unlike brass stopcocks which can easily stiffen up, making it ideal for those difficult to reach places. It works on the water pressure alone, using differential pressure to control the flow of water. The control can be fitted up to 2m away. WRAS approved and UK manufactured with a patent.
