.... If you want something more DIY-oriented: I once tried to swing down the bedroom radiator (to paint behind it or something) by loosening the joints at each end. This would have worked in our previous house, where the pipes were fairly solid and came up through the floor; but in this house, the pipes are thin-walled, and come out of the wall. So, of course, the joints failed. Cue much leakage of water, and of cussing (from Herself).

Happily, our plumber lives only just down the road, and was in, and has a sense of humour. As on the occasion related, I'd best leave it there.
