position as shown in Fig. 11.

and the pipe stop resistance is felt. Pull on the pipe to check it is secure and
correctly fitted.
5. To release the joint, push pipe firmly into the fitting, hold the collet down and gently
remove pipe. If the system has been filled with water care should be taken to isolate
the pump and towels used to absorb spilled water.
If you have any concern either about using push-in fittings or should the joint leak on
final test, isolate the water supplies and contact the Service Department on 01491
