Oatey Drain fitting
I am installing a shower pan using an Oatey threaded drain fitting. It came with a rubber washer.
Does this rubber washer go underneath the shower drain pan? I can't imagine it goes on top, because I intend to use silicone under the top.
Also, the threads in the female part of the fitting are interrupted. Will teflon tape seal the fitting well enough or do I need to use pipe dope?
Thanks

If your drain looks like this,(see image) then the gasket goes under the shower floor.

Please explaIn, what female threads are you referring to?
Never use pipe dope on plastic threads. It will cause the thread to slip when you crank it down. If I've put up the wrong drain image please correct me. Regards, Tom

That picture is not the correct drain fitting.
The Oatey drain fitting I am using is a two piece fitting with a female solvent welded lower section and a male threaded upper section. The threads inside the female lower section are not continuous. They have a tapered gap between the treads at the 12, 3, 6 and 9 o'clock positions looking downward. I don't know the purpose of these gaps.
My concern is that I won't be able to tighten the fitting sufficiently to draw the lower section flush against the bottom of the pan. The threads seem sticky as I tested the fit. I will use silicone caulk beneath the top where it rests on the shower pan, but I would like to have a good seal with the rubber gasket beneath, as well.
Thanks,

Would this be the shower drain you're referring to? Ifnot how about a part number or a picture. Cheers, Tom

Sounds like you're using the wrong drain assembly for the wrong application.
The drain you describe is for a mud-set installation, the drain you need for your application is the one in Toms first photo.
Did some research -- If your drain looks like this one, then installation instructions are linked at the bottom of the page.

Yes, that is the drain fixture I am using. The shower base has a 3 inch thick foam underlayment that has a 5 1/2" circular opening for the drain fixture. I originally got the one you showed first, but it's too wide for the opening in the foam and I didn't want to cut a lot of it away, so I went with the one shown in the second photo.
If it need to be set in mud, I can do that when we fill in the hole in the slab. Is it necessary because it might shift?
Thanks

Unless you're planing a custom tile shower then the first drain I posted is the one you'll be using. Cut the foam out and install the correct drain. Good luck, Tom
