Leak under kitchen sink

[sm30]

Hello everyone,

I have a slow leak under my kitchen sink when the tap is on. It seems to be coming from the top of the threads shown in the picture below.

Can this be fixed by tightening it or would I need to replace certain parts?

The amount of corrosion on the outside of the drain basket indicates it should be replaced. The threaded part on top may not be possible to tighten. It is not a difficult job. Just need a replacement and stainless plumbers putty. Please post a picture from top side.

The way the connecting nut show oxidation, it might be weeping from there. Using channel lock pliers try tightening the nut a little. It shouldn't move much.

Looks to be time for a new kitchen sink drain.

A new basket would be best. But if you want to try to fix what you have, loosen the nut that is just above your red arrow. Loosen the bottom nut if needed. Lift the basket enough to put stainless steel cauking under the top rim, inside the sink. Tighten again. Excess putty should extrude into the sink bowl. Remove the excess putty.

I think I am just going to replace the sink drain/basket. @WorthFlorida posted an Amazon link above, would there be any other parts I need? Or do these assembly kits include everything?

The short brass tail piece should be ok to reuse. Remove the lower slip nut along with the brass nut and it should come out and using a SOS pad should clean it up. A container of plumbers putty would be needed. Plenty of YouTube video's on the subject if you never did one before.
