A neighbour has asked my help cos their toilet won't flush. It's a Dudley, the kind that is built in behind a tiled partition so you can only get at the top. The flush works by air pressure with a plastic tube from the flush button. The end of the pipe that presumably is meant to somehow connect with the actual flush mechanism has come free, which is obviously why it has stopped working, but I can't for the life of me see wherre it is meant to attach. There is a green casing at the top of the flsuh mechanism with Dudley embossed on it, but I can't see anywhere where the pipe should go. Has anyone any ideas? I have the feeling it's probably dead simple. If it's not, I'll have to go and take a photo and post it, but I thought I'd see first if this is a terribly common problem with a devilishly simple answer!
TIA
