JOHN GUEST JG15mm Non Return Valve Plumbing & Water

The double check valve only allows water to flow through in one direction, therefore, preventing backflow of potential contaminants arising from back syphonage, back flow and cross connection.

A spring-loaded internal check valve is sited either side of the test cock and an arrow identifies the direction of flow. The low headloss design and fast installation time make this unit the ideal selection. The valve can be mounted in any position. The valve can also be used for domestic hot and cold water supplies. For use with liquids only.

To install, 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.
