The leak is at the bottom, so obviously putty on the top will not stop the leak. Being plastic, there is not a lot you can safely do to stop the leak. Putting pipe joint compound on the thread before tightening it to the bottom of the sink will usually prevent the leak, but it could also damage the plastic, which is why plumbers do not purchase pop-up drains made of plastic.

: I recently installed a new Crane china bathroom sink and an AquaSource faucet/pop-up assembly (all plastic)according to directions. Drain water is leaking from under the sink where the pop-up gasket is compressed against the bottom of the sink. The hole in the sink isn't perfectly round and the pop-up is a flimsy plastic device. Additional tightening of the pop-up nut makes the leak worse. The directions recommend not to use plumber's puddy at the top sink bowl opening. Any suggestions would be appreciated.
