In response to Re: ***RUSH HELP*** How do I Install a shower (fiberglass) base drain

: I bought a "Oatley" Brass no-calk shower base drain and am confused. 1). where does the black rubber seal go? on top or under the pan?

Below the pan, and then the friction washer.

2). what is the interior threaded ring for ("caulking nut") and how do I use it and what is it for.

It compresses the rubber seal tight around the pipe.

3). does "no caulk" really mean NO plumber's putty or silicone.

No, Silicone can be used to seal the flange of the drain where it drops into the hole.
No-caulk refers to the old lead seal that was caulked with a tool that spread the lead between the pipe and drain body.

3). do I use a "basin wrench" to tighten the drain and what is tight enough vs. too tight?

I use a large pliers. I do it tight enough.

4). the inner seal is ribbed (I'm installing it onto a 2" ABS waste line) is it just a friction fit or is it a compression fit - do I just "push" the waste line in as far as it will go?

Compression fit. A little soap can be used if needed. The compression ring should remain above the end of the pipe

Now you know why plumbers earn more than doctors.
