I hope someone can help. My knowledge of central heating systems is limited so please bear with me.
I have a boiler in the bathroom with a hot water tank and then have two tanks (one big and one small) in the loft. We haven't been in the House that long but the system cannot be more than four years old as I know the previous owner (a plumber) completely overhauled it.
The overflow from the tanks seems to leak constantly. It isn't just a small drip but a constant trickle. I'm not sure whether the source of the water is from the small or large tank but the trickle stops when I run the hot water for a couple of minutes only to return a few hours later.
Any idea as to what this might be and how i might solve it? Any help gratefully received.
The trickle is coming from the smaller tank. The 'extra' water is not coming from the ball valve but from the bottom of the tank (I can see the sediment being disturbed) which in turn comes from the boiler water pipe just outside the hot water tank. I also know this because the water is warm.
Please help! The constant trickle is getting the neighbours up three times a night.
Hi guys your problem with dripping overflow, I have had it for months, replaced the ball valve etc and still leaked. I had someone round to look and the diagnosis was a leak in the hot water cylinder (indirect system) which was causing back flow into the header tank.
I have replaced my hot water cylinder and hey presto no more drips....obviously try the ball valve first but if it continues it could be the same as mine
Hi Guys, just to say I've just had exactly the same problem.
After messing about with the ball valve ect. bit the bullet and
had the hot water cylinder replaced and no more drip.
Cut the top off the old cylinder out of interest and it was a
third full of limescale. Quite a mess. anyway all now seems well.
Not cheap mind.
