Hi peeps with Ballons! If you have a hot water Ballon does your valve at bottom of Ballon (called a Groupe De Secrite) "Drip" Its the valve which lets in the cold water from the mains and also lets you drain the water from the ballon. I have a new valve to fit as the one on it has dripped into the waist pipe for a long time now and the water we have lost and cost I'm ready to replace it but now it seems the one fitted drips a lot at times but sometimes it stops What I want to know is, is this what it does "as normal" is it supposed to drip Off and on (if you know what I mean) Thinking it needs replacing to stop the spasmodic drip but now thinking this is normal although the water it waists over time and the costs I don't want to think about. Ignore this post if you don't know what the heck I'm talking about ;D

Quite normal for it to drip.
Basicaly it's a pressure relief valve, when the water is being heated it expands, without the valve you would have a large hole in the roof where the tank exited.
So yes, should drip when heating the water.

Prob is tho P that the ballon drips pretty much of the time. Even when not heating (it switches thro to heat between 22:45 and 06:00) More like a dribble really. Could it be a duff washer? Its an old ballon - prob mid 90's or so (ish).

Maybe needs replacing, tis an old one.
Maybe dust in valve, open valve to flush some water through.
Maybe as the AI thread says your water pressure is too high.

Ta Pandj Have flushed through a few times but still the same! We do have high water pressure here so might see if a turning it down a bit will slow it down a bit

My memmory is not what it used to be, but, if I remember correctly inside the tank are two pipes, one for cold inlet and one for hot outlet, the cold inlet pipe is short so if replacing the valve you have to almost empty the tank. Of course I might have got that the wrong way around

Fli, this is a direct dictation from 'Mr Elkay': I assume your ballon is a French style hot water tank i.e. the cold water feed pressures the hot water from the tank top. If you have a problem with a constant dripping outlet it is best to replace the dripping valve. Each pressure relief valve/outlet has a Bar (pressure rating) usually market on the front of the fitting. Ours is market at 6 Bar which is about twice mains water pressure. He says 'does that help' and 'would you like to give him a ring' (Ali has our number) All the best from the Elkays

Lol - you have both of us on this thread I reduced the water pressure at the mains a few weeks ago just by turning the stop tap down - didn't have any effect (I'd read the Ai thingy too) - still dripppppped, dribbled. Fli can stick his hand down the inspection thing, akky toads...
