I have a 3 valve type faucet for my bathtub. I have changed washers and valves in the past but this time I can't get the handles off 2 of them. They are stuck to the stems. I've tried tapping them with a hammer and WD-40. Any suggestions for getting them off, Thanks

Most hardware stores sell handle pullers,(see image) They're made for those stubborn handles. Good luck. Tom
