The flimsy chromium-plated plastic bush that is screwed into the side of the loo cistern holding the loo handle in place has cracked beyond repair (what a shoddy piece of "engineering" it is too). I have no idea of the make of the loo -- the manufacturers were not proud enough to put their name on it. It's about 10 years old.
Is it normally possible in such situations to get a replacement handle assembly from one of the sheds, or from anywhere else, or do I need a complete new bathroom suite?
