John Guest 15mm Double Check Valve – prevents backflow

How it works
The valve has two spring-loaded check valves, one on each side of a test cock. An arrow on the valve shows the direction of flow. Push the pipe straight into the push-fit ends. To disconnect, push the collet towards the valve and pull the pipe out. The valve can be mounted in any position.
