Sink seal leak

[Jrknakmuhs]

I have a 1984 Jayco pop up, 1008 SG. The flip over sink tends to leak between the sink and gasket in the cabinet. Replaced the drain and deal but still tends to leak. Anyone have a trick for this?

Did you change the gasket on the drain itself? Mine unscrewed from the bottom and I was able to use a gasket off the shelf at Lowe’s.

Household sinks also use "plumbers putty" between the sink and the bottom on the drain that is on the top of the sink. "how to use plumbers putty, easy as playdough' youtube or similar. buy the smallest amount you can as it takes very little and will probably dry up before you need it again.
This may solve your problem.
