Well the drip didn't stop after 30 minutes, so I'm guessing the drip is permanent till I can fix it. I even put in a new washer and it still drips. The only thing I can think of is maybe solder got in too far and is obstructing where the washer is seated. I'm thinking of shining a flashlight in there to try and see if I can see solder on the seat, but even if I do find solder there I don't know how to remove it... I am definitely not up for redoing the entire sillcock so I don't want to cut it out.
