I have an issue with what seems to be a self opening valve..
Had a plumber out today to look at a leak from a pipe in the bathroom.
He found the leak was from an old isolation valve so he's fitted a new one. The pipe its self is cut off, I believe it was connected to an old hot water tank which is still there but obsolete. Instead of capping the water supply to this pipe, he's just put a new isolater on (he says as we're planning on putting a new bathroom in in the future, best to leave the supply there)
Plumber says the valve was 22mm (i might have misremembered that part) but he's fitted a 15mm.
Anyway, the same thing happened with the new valve, I isolated it, plumbe returned and said, there cant be anything wrong with it S its new. I tried explaining its somehow opened on its own but nothing more could be done.
Its now happened two more times.
I can't find anything that's causing it to open. It's happened once when I've switched the boiler back on, but the other times the boilers been off so might be a coincidence.
Dont really want to pay for another plumber yet, as I can isolate it myself, when it leaks. The trouble is I can't leave it unattended as its happening randomly(seemingly), so dont want to come back to a worse flood than before.
To top it off the main stop tap has seized (old house and recently bought it) so we can't switch the water supply off completely if going out/to bed etc.
Any ideas on what could be causing it?
Ive ran all of the taps, flushed loo etc and switched boiler on and off a couple of times again, but its not happened after that.
Could I just put some sort of glue to completely seal the bit that you turn, to stop it from opening?
