How to remove stuck shower diverter stem

8 years ago

last modified: 8 years ago

Hello,

I am new to this forum. I have a old bathroom with a 3 stem shower valve. The shower diverter stem needs to be taken out and serviced (when I want the switch the water from the tub faucet to the shower, using the middle diverter handle, there remains still small steady stream coming from the faucet. ). I think the diverter has not been serviced in decades (there was alot of crud on the escutcheon and both the escutcheon and the diverter handle required alot of force to remove).

Now, I am trying to remove the valve stem but the previous owner tiled over the valve stem and I had to cut some of the tile to access the valve stem nut which I tried to loosen using a the appropriate size valve socket . BUT NO LUCK, even with quite a bit of force and using a crescent wrench for leverage, it would not come out. See photos.

Any suggestions on how to loosen that nut (it's the one in the back, I think) to get the valve stem out?

Sometimes there is a C-clamp that needs to be removed first and they have a special tool to remove the stem.

We just watched an Ask This Old House episode where Tommy showed a homeowner how to do this. Also, I remind DH ,”They have people who do this for a living and have all the right tools-plumbers.” The money you spend could be less than the money to fix a disastrous diy.

If you're committed to trying DIY, first thing that I would do is spray it down with a penetrant. Two or three times a day for two or three days. Then try to remove it. To get more leverage, try slipping a cheater over the end of the wrench/ socket handle.

And be prepared for the possibility of having to replace the valve. Hopefully, you have access to the the valve from on the other side of the wall...

Sorry, I don't see any C Clamp, I ended up chiselling all the grout-like material that is attached to it because I believe that the whole thing in the picture is the valve stem that needs to be taken out. Even doing that, I can't remove it. I am giving up and putting everything back. I can live with it until I can't, at which point I will call a plumber.

Here's a link to a YouTube video of a plumber replacing the diverter valve. Just fast forward to the 3:40 mark in the video to see how he removes it. If this doesn't show you the info you need, there are a lot of other videos on YouTube that show how to replace the diverter valve so maybe one of them will help you.
