I have four bathrooms in our home and we never use the shower over the garage. When I checked it out today the hot water will not come out. I have a single handle valve which starts out cold and when I turn it it moves over to hot. When it gets to the hot side, there is a little drip. I don't know if there is calcium deposits or what I can do to replace this valve. I think I need a special tool?

If I had to guess, it looks like it might be a moen, but can you get a close up picture of the stem with the handle removed?

Alrighty, First shut the water off. second remove that chrome sleeve-just pull straight out. Next you have to remove that brass/copper colored clip-BE CAREFUL!! don't drop it back in the wall or down the drain. (voice of experience here) To remove it you have to take a little screwdriver and pry up on the little hole in it. After you get the clip out pull out on the stem. It might be tough, sometimes you can twist while turning. I think that is a "posi-temp" stem, but take it with you to get a replacement.
You will have to leave the water off during all of this, so make sure your old lady takes a leak first.

We are assuming the water flow problem is caused by this defective stem. Most of the time with faucets it is the stem/cartridge but rarely it is something in the supply pipes, but if I was having this problem at my house that is how I would proceed. GOOD LUCK!! keep me posted!

broox - I learned that from experience also. A simple way I came up with to avoid dropping it behind the wall is to tie a long piece of dental floss through the little hole and hang onto it.

It should be a Moen 1222 cartridge

Stem will not budge

I removed the clip and am now trying to pull out the stem and it will not budge. Do I take the plastic part out or does it all come out as one unit?

Time for a plumber...

Well, I tried pulling the stem out and it cracked...it will not budge out of the sleeve. Probably calcium build up holding it in.

It should all come out as one unit. I take pliers and pull on the brass, or take needle nose and try to rotate the plastic back and forth, then more pulling.

Thanks...but I believe if I pull on the brass, it will crack more.

The plastic has notches in them so you can twist them. I think it is plumber time. But I really appreciate the help.

Don't give up unless you really want to!! If I had to guess, I would say all the other shower valves in your house are like this. At least ask to watch the plumber repair it, so next time you can do it!
