Not a plumber by trade, so please cut me some slack.


What is the standard thread size for a sink strainer under the counter?
Is there a fitting that is threaded female on one size and smooth female on the others that I can glue in schedule 40 PVC?



I want to replace the metal tailpiece but want to use a fitting that will allow me to connect to all schedule 40 p trap avoiding the thinner walled PVC tailpieces. I can't seem to find one that will thread right on to the sink strainer thread at HD.

Any input is appreciated.

Get a brass one

Basically the one in the picture below with the correct thread size.

The strainer is 1½" pipe thread, but it is not tapered like a normal pipe thread because it is not designed to be used as a pipe thread. You can get commercial strainers that have a tapered thread on them, nice heavy brass ones, you will pay for them though.

Not sure why you would want to get rid of the metal pipe or what you are ultimately after, but here's a way to get close to what it sounds like you want.

Go get a glue on 1 1/2" trap adapter. Leave the metal, but cut it off to about two inches and then build your PVC P-trap and whatever else.

You want to replace a metal tail piece...but avoid a thin walled plastic tail piece.

Solution, keep the metal one.
