John Guest Speedfit Double Check Service Valve 15mm

The double check valve is a John Guest push-fit valve for the connection of plastic and copper pipe. Designed, manufactured and assembled in the UK by John Guest Speedfit. The valve only allows water to flow through in one direction, therefore, preventing backflow of potential contaminants. This particular check valve also has a built-in isolator making it two products in one! Simply push the valve fully on to the pipe. Should the need arise to demount the connection push the collet towards the body of the fitting and pull the pipe to release.

Installation can be reduced by around 40% against traditional fixing methods.
