I had a faucet that was leaking from the cold water handle when either the hot or cold was on. I changed out both the seats and stems (went to a faucet supply store to get the exact parts) and the handles feel great, but now the faucet is dripping like crazy. I’m worried the faucet itself is cracked, but then wouldn’t it have leaked before I fixed the handles? Also, if I turn off the water main, the faucet will continue to drip unless I open up the faucet on the outside of the house. Any suggestions?
