Moved into rental in October. The landlord is unpleasant so would rather not contact him if I can avoid it.
Realised this morning (half way through washing my hair!) that the boiler has lost pressure. I've watched several YouTube videos but just can't seem to get the filling key into the filling valve. It seems too big and won't go in no matter how hard I try.
Does anyone have experience of these types of boilers who can help me figure this out?
Many thanks!
