I have a Sealed system (vented DHW) and 2 days ago the overflow in the water tank in the loaf started gushing out water. It then stopped one evening but has since started up again and continued gush water none stop.
We had a problem like this last year and it seemed to right its self but it did not go on for this long.
It still gushes water weather the hot water is switched on or not and the heating system is off.
I took the lid off the storage tank in the loaf and found it was filling up without getting water from the cold in or the expansion pipe. So I put my fingers over the cold out and could feel a strong pressure of water coming back through the outlet.
When I blocked this flow with my fingers, water would then start to come out of the expansion pipe.
Would appropriate any information on what might be wrong or how i could temporary stop the leaking water, in till the problem is fixed.
