Gerber 3 valve faucet for tub/Shower

After much trouble I was able to remove the faucets, stems, and seats and replace them with a new Gerber kit. Now instead of my cold water faucet leaking badly, my hot water faucet is leaking badly. The issue is that I had to work so hard to get the old hot side seat out, I think I may have destroyed the threads so that the new seat will not tighten up.

What can I do now?

If you have destroyed the threads on the old valve body, you will need to replace it.

I often will cut the tile to remove the old valve, and install a new pressure balanced single handle faucet.

Trimmed with Moen repair plate and the "Moen Level" tub shower trim.
Now if they ever have an issue, there is the lifetime guarantee from Moen on the cartridge.
And we "know" what it is this time. It's much easier to "dial" in the temperature too.

YOU do not usually destroy the threads when you remove a seat. That usually happens when you install the new one and do not get it caught straight which cross threads or strips the threads. Some plumbers have taps to restore the threads, even if they have to go to a larger thread and seat.

Before you screwed the stem in, did you make sure the valve was open?

Did you replace the seats too?

You may have to take it back out. Clean it up good and reinstall it. Make sure nothing is cross threaded.
