I have an older am stand single handle bath/shower faucet that leaks.
I can get the handle and cover off but cannot get the the stem out.
There are no clips so I assume it unscrews? I am afraid it will break
with force needed to unscrew. I have soaked with Kroil oil with no
luck. Does anyone know how to get this out to replace washer?Faucet is
probably 30 years old.
