Yes tried that. Hot water works on ground floor when heating is on but very intermittent on second floor? All worked perfectly fine until I drained down and refilled system?
Hi all, I drained down my heating system to relocate a radiator, ever since when trying to use the shower on the second floor( boiler located on ground floor) boiler stops working, fault light- pump or low pressure comes on. Any advice on how I can fix this please.
Cheers in advance
Thanks for your reply, already put a new rad on but nothing is working but even got any running water through hit tap now. I am convinced there must be some sludge blocking the system. Another thing is , when I drained the system 2 out of 3 ground floor rads would not drain and also have no air...
