Leaking bath tub faucet
I am trying to repair a leaking faucet. I thought replacing the knob with a new one would to the trick but no such luck. I think an o-ring needs to be replaced but I am having trouble removing the cartridge to check it. I have a fix-it book that says to remove the retainer clip (which I did) and then remove the cartridge - sounds simple but the cartridge will not budge. I hate to call a plumber for a simple repair like this. Any suggestions?
