My kitchen drain came apart, it is like 12 years old. I noticed it is not a locknut connection, so I am not sure how to attach these parts. The sink strainer itself is loose and I can pull it out easily, so I was wondering if I need to reseal it as well? Above the connection you see a black washer. Any advice?
UPDATE - Per Ben's advice after looking closer I could see it did have a drain screw and it broke in half. Below you can see what it looks like. Now I just got to find this part and replace it every 10 years from now on.
UPDATE 2 - I shopped around to a big box and a plumbing supply store, but it seems such retaining screw is rare and none of them ever recall stocking such a part. They also said that was a unusual way of making such an assembly. So I am just going to replace it with a Deep Cup Strainer that should fit in perfectly. If that screw went after 12 years it is bound to go again. And since this is a double sink, I am going to replace both of them.
