Stuck Valve Stem
I recently changed the valve stem on my tub faucet and I'm trying to change the other one, but it is stuck. It looks as though the stem has never been changed--at least 15 years. I sprayed WD40 but no luck. Do I need a professional to do this or does someone out there have a better idea? Thanks.
Maybe put a little heat on it, make sure you have the correct wrench, and it's not binding with the wall, try to heat the pipe enough for it to expand, then put some good pressure on the nut.
