I have a leaky ballvalve, in an Ideal Standard/Armitage Shanks cistern.

I phoned Ideal Standard's help line and they very kindly send me a kit of
replacement washers and a new diaphragm.

Having struggled to take the thing apart, I'm totally baffled how it should
work. The Ballvalve cap in the centre of the picture fits over the top of the
diaphragm, but I fail to understand how the float arm, that fits on hinges on
the top of the cap, can possibly do anything ? There's a tiny hole that a
rubber bung in the float arm sits over when the cistern is full.

And where does that red plastic valve come into play ? Needless to say I've
reassembled, and it doesn't work, though it did before dissembly !

Can anyone help please ?
