Calling everyone whos experienced in plumbing!
The Ballcock valve is not switching off due to limescale(i think) causing it to overflow.
Based on the picture could anyone give me any advice what i need to do to fix this and if they know what kind of valve it is before i call in a plumber as i don't like messing with water?
I am kind of hoping i can easily unscrew something remove a limescale deposit to fix it easily.
Thanks for any advice.
