Dear members, Advice wanted please. I have just moved in to a new place and within 3 weeks we have a leak from the shower into the dining room :x At first glance I had hoped it was a simple failure of the sealant between the tray and the tiles (and it had come away there) but the...

many thanks indeed!

aha! better picture: http://www.wessingtoncryogenics.co.uk/Needle%20Valve.jpg is almost exactly what it looks like.

afraid i don't have my camera at present (lent to my sister for her hols!). i'm not sure i'm necessarily using the correct terms (i.e. "valve" vs. "stopcock"). however, the leaking part is basically a red circular metal tap. it's attached to the pipe by a nut on either side. if you screw it...

hmm, that sounds a bit worrying. i can just about get to the leaking part at arm's length. is an external sealer of any use?

hello. i have a small leak in a pretty inaccessible place (would need to knock through a stud partition wall to get to it) in the return pipe from the hot water cylinder. it's located at the site of an isolation valve. i've tried fiddling with the valve but it still leaks. are the internal...

there's nothing on the pipe going into the side of the cylinder other than an isolation valve which is open.

feed tank is about 2/3 full.

thanks for your help. i can't see an air vent near the cylinder. how can i tell if there is an air lock? and if there is, how can i clear it? presumably it is not in the central heating system as this works fine (i have bled the radiators in any case). i'm pretty sure the valve is OK from...

i have noticed a problem with my system since using it just for hot water rather than for both hot water and central heating. there is a gloworm 18hxi condenser boiler in a Y-plan style setup. when the boiler is set for both central heating and hot water, everything is fine. However, as...
