Hi there,
Just had my system sorted after a rad pipe split! (That was fun)
Anyway, had new ball cock installed in expansion tank as last one was seizing. Now the tank keeps overflowing. I have dropped the ball as low as it will go and it still overflows. This only happens when the heating is turned on. As soon as heating turns off, no more overflow. It doesn't seem to happen with HW.
Should I readjust the ball cock or is there something else I can do?
Thanks! Tim
