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.
Many thanks in advance.
