My Feed and Expansion tank in the loft is overflowing occasionally. Not dramatic, just a trickle now and again when the water is being heated. Pretty sure it's not the ball valve. My system is ancient, but it works (mostly !) Does have the tendency to overheat occasionally but |I've never had the overflow problem before. Whats confusing me is that the water in the tank is cold, is that right ? Will bleeding all the radiators help ? Guess I'm going to have to call someone out eventually but I could see them condeming the whole system .....
Is there anythong else i could try/look at before I do that ?
Many thanks for any advice.
