Just moved to newish house and within weeks two damp patches have appeared in 2 room ceilings! I have cut a hole out and found a leaking JG speedfit Tee fitted to a grey pipe which supplies HW to a bedroom. Now I thought JG pipe should be white not grey which makes me wonder that the original builders have used none matching fittings throughout the house!
Until I take it apart I cant tell if end seals have been used but our system does run at quite a high pressure. This is a big worry as two leaks are already evident.
Not checked the other damp patch yet but its on the same run line I suspect and its not the central heating.
Now I cant find an internal stop cock so guess I'll need to turn off the house supply from the drive cock but with a main pressure system would I just run off the hot water til it stops before disconnecting HW pipes?
On reconnection will the cylinder just re pressurize itself or is it much more involved? (I realise I shouldn't mess with the pressurising system itself).
Ideally I'd like to repair a dripping tap whilst the water is off and fit a number of isolators too and as few seem to have been fitted and its only an 8 year old house.
