Isolation valve problem
The screw in my isolation valve has jammed. How can I release it?
Quite a common thing to happen limescaled up no doubt, try some wd40 if not successful, you have no other option then to change it.
Good luck, Mario The Plumber, Horning, Norfolk.

Bang gently with a hammer, may free up limescale deposits and then give it another good twist.
