We have a double sink. One sink works fine, but the other drain leaks if the sink is full of water when the stopper is pulled. I can see it dripping from the bottom of the P-trap, but can't pinpoint where the water is coming from. It works fine with simply running water, or if it contains a smaller volume.
I should add the plumbing has worked fine for 20+ years; this is a recent development. Any ideas of what I should look for?
