We have a Crane Drexel bathtub faucet that leaks from the cold side. I replaced the cartiridge and washer (I also put a new washer on the hot side and it continues to be just fine.) The cold continues to drip, but not as bad as before. As my two-year old says "it's dripperring!" Any suggestions to how to get rid of the drip (drippering)? Thanks...
