Hi All, Today the overflow from the tank that supplies the hot water tank started to overflow.
On inspection I find that the water that is going into the cold tank is hot water coming in via a pipe at the top of the tank.
at the same time I have wanted to bleed the hot water tank (there is a pipe coming out of the side of the hot water tank and coming up the side with a bleed valve like on a radiator) but nothing comes out niether water or air which is what normally happens. Can someone help? are the two connected?
