I've replaced both hot and cold side valves (St. Thomas brand) about two years ago at $40.00 each. Now the faucet is dripping again. I've taken the valves out and they look good. There does not appear to be a replaceable seats in the fixture. Should I lightly sand the seat with some sandpaper? Try to find a replacement rubber rings in the bottom of the valves? Buy a new fixture? Tighten the hell out of it?
Basically out the blue it will start dripping. Sometimes if I open both hot and cold sides at the same time and then close them quickly at the same time it stops for many hours but eventually starts up again. The sound drives me nuts. Thanks.
