Question about tub waste drain Tee

[udelslayer]

Does the tee in the drain assembly need to be a sanitary tee? I noticed the complete kits come with a tee that looks like a straight connection (propylene and brass). I see that a lot of the plumber's when using the "packs" use a sanitary tee. If the tee isnt a requirement by code (even if best practice), and I find some of the Gerber Brass units have a 3 way side drain tee configuration, can I use this with PVC too? I'm trying not to have to cut much of my existing trap or the joist.
Can anyone think of any issues using this? Just hooking up a Kohler Expanse tub in the second floor bathroom. The down section will connect to the p-trap.

Example:

Gerber Classics™ Pop-Up Side Outlet 20 Gauge Drain for Standard Tub with Brass Nuts

This doesnt look like a sanitary tee, but it sure is fancy.

PVC:

Formufit 1-1/2 in. Furniture Grade PVC 3-Way Elbow in White (4-Pack) F1123WE-WH-4 - The Home Depot

The FORMUFIT 1-1/2 in. 3-Way Furniture Grade PVC Elbow in White can be used to create corner or multi-plane elbow connections in PVC applications. This PVC elbow fitting connects 3 segments of 1-1/2 in.

1. Sanitary tee is important for the output of a trap arm, but the stuff in your picture is from before the trap. So no sanitary tee needed in what you picture.

2. Furniture grade PVC is not approved for plumbing.

Nice catch. Didn't pay attention to my example for the post and have never heard of furniture grade. I had actually been looking at this one:

Thanks for the confirmation!

That's not a drainage fitting, it's a pressure pipe fitting (for pressurized cold water). So its use would violate IPC 706.1

Will the tub waste and overflow be accessible after installation? If so, tubular parts are OK to use, and you can get the style in the OP in either brass or plastic.

Otherwise, you need to use solvent weld plastic, and you'd be best off just modifying the tub trap arm and relocating the trap as required.

Glad I asked (and I'm not surprised lol) Didn't realize the materials would be so different. Yes. Its going to have an access panel as well on that side for getting into the space. I dont have to cut up through the ceiling. I'm sure I can come up with a cleaver combination of approved fittings. This is fun!

I guess the solution is easier than I thought, but it almost seems like you're not supposed to do this - rotate the drain shoe (left or right a few degrees) and use a couple of 45's to make the overflow meet the sanitary tee.

Like this guy:

Mine isnt as dramatic and also meets the trap and then horizontal waste arm, but since they offer flex hoses for overflows (not a fan) then this is the next better thing.

not a big deal swinging the shoe those brass tub kits arent santees. My guess they are aprooved Gerber is a major player. I dont even know how to tell but each and every piece technically needs aprooval back in the 90s we were getting cast iron drainage pipe made in china guess they didnt pay thier bribe some work had to be torn out for not being approoved some of that china pipe wouldnt even snap with cutters it would shatter had to use a chop saw with it to get a decent cut
