I've just used an in-line tap to turn off water supply to an outside tap. It has a compression fitting each end and is operated with a screwdriver. However, the metal is very soft and the driver no longer grips it and I have been unable to fully turn it back on.
Does anyone have any suggestions of how to rectify this problem? If it involves replacing the in-line tap is this easy to do, or should I get a plumber?
Regards,
Ian
