Hi,
I have a flat with a heating system approx 30 years old. I have a boiler in kitchen, hot water cylinder in airing cupboard and two tanks in my loft (a big cold water tank and a smaller central heating expansion tank).
In the last few weeks, the overflow from my central heating expansion tank began to steadily drip.
I called a plumber out, who suspected a faulty float valve in the CH exansion tank so they replaced it and set the valve to it would not rise too high.
A few days latter the drip returned. Taking a peak at the tank, it had filled back up to a level just above the lowest point of the overflow pipe, hence the drip.
If the central heating system is turned on, there can be a sudden stream of water shot out of the overflow pipe, before it eventually calms down and the dripping stops completely. Once the heating has been off a few hours, it starts to drip again.
Any ideas what could be wrong, and what I could do next?
Many thanks,
James
