Double check valve for the push‑fit connection of plastic and copper pipe, designed and assembled in the UK by John Guest Speedfit. It allows water to flow in one direction only, preventing back‑flow of contaminants. Installation is as simple as pushing the valve onto the pipe, reducing installation time by around 40 %. The valve is lead‑free, non‑toxic, scale‑ and corrosion‑resistant and is BSI and WRAS approved.
