Shower stem valve

[Gin1396]

I was going to replace my hot water stem valve and the old one is stuck . Won't turn doesn't budge. I have used silicone lubricant and everything and nothing . Any suggestions to what the problem might be ?

You are replacing the valve on the hot water stem? Please clarify.

Won't turn, doesn't budge. What doesn't turn? The valve? The threads to replace it?

And everything and nothing. Have you tried PB Blaster? You may need to use two wrenches, one pulling and the other pushing, in order to remove the threaded on valve. Are you sure it is threaded and not soldered?

In this case, a picture is worth a thousand words. Please post up a picture so we can help you.
