The mixing valve in my old shower was working well but now only delivers cold water. Looking inside, there are two valve ports for hot and cold with a heavy spring on top of each and a bronze yoke spanning across them both. There is a screw in the middle of each spring fastening the valves to the yoke. The yoke moves in and out with the turning of the mixing handle. The screw on the right (hot), seems to be stripped because it turns around and around without coming out. I assume this is why it no longer delivers hot water. I can't start getting violent with getting it apart until I know how it is going to be fixed, because once it is apart and can't be shut off, I won't be able to use the tub either since both are on the same supply lines. I really, really do not want to rip open the wall to put in a whole new unit because the whole room is done in irreplaceable black glass. I do not understand exactly how this valve works. Can anyone explain it to me? Can anyone identify it from the pictures? Are there any diagrams or parts available? About how old is it? I do not know the actual date of the bathroom remodeling but assume it was in the 40's.
