We have an Ideal Standard shower unit, installed in 1985. It's one of those contrivances where you pull the single lever out towards you to make it squirt, then rotate it to control the temperature. It's worked very well until recently, but now the flow has reduced itself to not very much. I think either the innards are clogged (although we are in a soft water area) or the lever has developed some lost motion and the valve just isn't opening fully. (The lever might be looser than it was....it's hard to recall)
The problem is, I have failed miserably in my attempts to dismantle the thing. I haven't found out how to get the lever off, or even how to remove the chrome cover. I can remove the 2 screws retaining the latter, bit then progress is impeded by the threaded nipple that the hose screws onto.
Help!
