Designed, manufactured and assembled in the UK by John Guest Speedfit, this double check service valve is used for the connection of plastic or copper pipes onto a male thread appliance. It allows the water to flow in one direction to prevent backflow of potential contaminants. This push-fit has a built-in isolator that helps in maintaining the valve. Should the need arise to demount the pipe simply push the collet towards the body of the fitting and pull the pipe to release. Note: With all plastic pipes the relevant manufacturer’s pipe insert is required.
