There was a gauge next to filling loop in the loft! It's still sitting on 2.4 - 2.5 I bled all the rads and took about quarter of a pint out one of them, should I just carry on taking water out?
Hi have a vaillant ecotec plus 615 displaying the f22 fault, I understand that the system need to be filled up but can't find any levers to do this! the only braided pipe I can find is in the loft near the cold water storage tank but again no levers. Anyone able to give me any pointers please.
