sink is leaking at the point where the pipe attaches to the sink drain. When I took this apart, there was an o-ring under the flange. The entire joint was also thoroughly smeared with silicon caulk - so this leak is nothing new.
It's my understanding that the only gasket
needed is the white one shown and that the nut only needs to be hand tight.
I can't get this to stop leaking, no matter how hard I crank on the nut. Any suggestions on how to fix this?
I'm tempted to try putting butyl tape under and over the pipe flange. I'm afraid that if I start replacing parts
I'll end up having to redo all the galley plumbing
