Greetings!
I am looking for some ideas here. I have just installed one of those one-piece marble type sinks. After installing all the plumbing and gluing the sink to the cabinet with Silicone seal as described in the instructions, I noticed that the drain hole on the bottom is slightly crooked. When I put the large nut on from the bottom, the rubber gasket contacts the sink and squishes on one side only. When I run water in the sink, it leaks from between the rubber gasket and the chrome drain pipe. I am assuming it is due to the gasket not contacting everything evenly.
Since I have every thing installed, is there a way to stop this leak. I don’t want to remove the sink as I think I would damage the cabinet in the process.
I don't want to make the nut any tighter as I am afraid of damaging the sink.
The instructions say not to use plumbers putty as it will damage the sink. Should I use Silicone seal on the gasket? Any ideas?

rpokorny, Welcome to the DIY Forums.
Plumbers putty has some sort of a reaction with Marble. The drain is leaking between the chrome ring and the sink. You will probably have to use silicone in that area. Thats where the plumbers putty would normally go. Loosen the nut under the sink and disconnect the trap. Push up from underneath and apply silicone under the chrome ring inside the bottom of the sink. Pull the drain back down and tighten the nut again. Take a wet rag and wipe the silicone off the surface of the sink where it will squeeze out. Let it cure for as long as possible before using the sink. Silicone tube should have curing directions and times. Good luck on your project and reply back with any further questions.

Finally fixed the leak. I removed the gasket and spread silicone seal on it and re-installed everything. No leak. Working on these is sure hard on the back.
