I had a faucet drip in my bathroom sink. I determined it was the hot water (confirmed by the warm drip and it stopped when I shut off the hot under the sink). I assumed that the stem went (which happened before, to the cold stem) but after replacing it and tightening everything, I still have the drip. Can I assume the faucet needs to go? It's an old Price Pfister.
Note: The plumbing and shutoff valves are new but the faucet assembly is old.
