I have a single-handle Peerless faucet in my kitchen. It has a persistent drip that I've attempted to fix a couple times. The drip is out of the faucet end (aerator) itself, not from around the base or handles. I have replaced the seats and springs twice, and the ball assembly and diverter another time. After each attempt, the faucet doesn't leak for the first five or so usages, then the leak returns. The faucet leaks if the handle is in its normal "off" position (bottom center), but if I maneuver the handle a little up and left, the drip stops.
Based on that behavior, I think that maybe something is shifting, loosening, or becoming unseated. Do I need to start replacing gaskets, or am I missing something here? What can cause this behavior, and how can I fix it once and for all?
Thanks,
Stavros
