It's not leaking from the rubber gasket. It leaks from the bottom of the screw nut. Should I just use silicone. Thanks for your help.
Hi Vic, Thank you for your question. You will want to install silicone on the underside of the drain flange where it goes into the sink. The silicone in combination with the rubber seal and nut coming up from under the sink should seal the drain assembly.
