I have dripping from my feed/expansion tank overflow. This only occurs when the heating on and boiler fired up. When the heating is off then the overflow does not drip at all. I left the heating off for about ten hours with no dripping.
The dripping water appears to be cold but not looked in the roof yet. Surely if the ballcock valve was leaking then the water would drip constantly. I have not adjusted anything and the heating appears to be working ok.
Any ideas, thanks in advance.
