Check Valves

A check valve (or sometimes known as a non return check valve is a device designed to allow the flow of a substance (in this case water) in one direction whilst preventing it from returning in the other if the supply pressure should drop. Here at On-Demand Supplies we stock a wide range of double check valves in various sizes, such as your more standard 15mm and 22mm, as well as much larger sizes.
