Kitchen drain installation [View all]

I'm trying to install a new drain in my kitchen sink after having removed a garbage disposal. So, I have the drain with its sink strainer, then a 1.5" flanged tailpiece washer which fits inside a 1.5" flanged tailpiece, then the slip nut joint... correct?

It leaks! Do I need to put that pipe tape around the threads of the drain that the slip nut joint screws onto? It seems so strange that the strainer and a hard washer just butt up against each other and a screw-on collar is supposed to seal that together. I don't see how it would NOT leak.

Also, when I look down through the drain, I see this washer smaller than the drain's strainer above it. It effectively reduces the diameter of the pipe at that point. Is this correct?? I just foresee little bits of gunk getting caught between the criss-cross of the sink strainer and this washer, never being able to flush down. Is this really how it's supposed to be? Is there a different kind of washer I can use here rather than one that looks like this...


The guy who was supposed to install this never showed up, so I'm D-I-Myself. Hey, I took out the disposal and old faucet, and installed a new faucet successfully. I thought the drain would be the easy part

Any insight would be appreciated!
