Hi
I have just moved into a house and there is a leak coming from the overflow from the tank in the loft. Clearly the ball float is not shutting off and I see that it is a Portsmouth valve, the problem is I don't know how to adjust it. Can anyone offer any information on how to do this. Also, I can't seem to locate the mains tap to shut off the supply.
Thanks for any help
