Hot water is flowing from the hot water cylinder into the header tank through the header pipe (reverse flow).
No water is passing through the expansion/overflow pipe from the top of the cylinder into the cold water header tank.
The expansion/filler tank for the central heating is constantly refilling.
Any comments suggestions will be gratefully recieved, thank you.
