I installed a new drain/pop-up assembly in a new bathroom sink and I can't get it to stop leaking. It seems to be leaking between the Mack washer and threaded section of the pop-up body. I have tried tightening the locknut in half-turn increments to no avail. Is it possible that I have over tightened it causing a distortion of the Mack washer and the leak? I didn't have this problem the two previous times that I installed a similar assembly.
