I installed 2 identical, new, porcelain vanity sinks. One is fine the other has a leak. The leak comes from one specific spot where the hole in the sink and the cone shaped gasket meet. Upon examination, there is a defect in the sink hole - it is small but noticeable and may be about 1/8" deep and 1/2 " long on the edge that contacts the gasket. I tried a new gasket but that did not help. Suggestions on how to fix this? Thanks in advance for your help.

Remove the assembly and apply silicone caulk to the gasket, then reinstall.

OK I already tried plumbers putty on the gasket to no avail. I will try the silicone. Moen was good enough to send me a new gasket and a metal assembly (now have plastic). I will wait until it arrives to use the silicone. Assume I need to wait for the silicone to set before running water through it? Thanks again.

Bought 2 at a garage sale - they match and were new. One is fine, just have to salvage the other. Additional suggestions welcome. Thanks

The better choice would be to return the defective sink and get a good one.

In that case, silicone caulk may be the only option if it works. Metal or plastic pop-up is immaterial.

your problem is minor not major. there is a difference between a metal drain and a plastic one. the metal you can get tighter. the plastic will crack if you try to make it too tight.
anyway, clean off the plumbers putty. put the silicone under the sink flange and apply a generous amount to the bottom of the sink. tighten very firmly..
i don't wait for the silicone to dry completly before use.
wipe up any silicone with denatured alcohol befor it sets.

Packy, thanks for the details about how to proceed. Do you tighten immediately or do you allow the silicone to set up a little so the surface of it is a bit firm? Thanks

Possibly, or you may get lucky.

Plastic drains usually have a more resilient gasket, however, because they cannot be tightened excessively.

tighten immediately. make sure you get good squishage (pronounced... squish-edge). wipe off any excess for a neat appearence..
