I'm new here... help would be very appreciated!
I'm having some trouble with my boiler, t's a Glow Worm 18sxi and can't maintain pressure. After a bit of investigation I think it's the safety valve that's the problem (it's dripping).
The replacement part isn't very expensive, but can someone tell me how easy it is to fit? I'm quite tight on space - the side of the boiler is meant to swing outward but can't because the wall is in the way. I've attached a photo.
