The John Guest double check valve ensures water only flows in one direction to prevent backflow. Simply push the valve fully onto the pipe. To disconnect, push the collet towards the body of the push-fit fitting and pull the pipe release. The double check valve is up to 40% faster to install than traditional methods and is easier to use in confined spaces because it doesn’t require tools.

• Grip & Seal collet with stainless steel teeth and main O-Ring seal
