 1-1/2" sanitary tee horizontal for fixture?
Author: remofool

I know most of the time san tees are limited to vertical use. For a double sink with disposal set up with separate p-traps, is it permitted to use a 1-1/2" sanitary tee horizontally to connect the trap outlets to the drain stubout at the wall?

I don't know what plumbing code you're under, but you might not be legally able to install 2 traps on 1 trap arm.

As a way to avoid using an end outlet baffle tee at the disposal. But it looks more and more likely I'll be doing it the way "everybody" does it.

look at it this way .

if it goes through the baffle your line should never clog.

personally i wouldnt have it any other way. i dont like having to snake my own lines. its much easier to take the baffle out and clean it if needed.

Thanks all for the commentary. There's a lot to know about all those fittings in the bins. I'll try setting the the disposal elbow down into the top of the baffle tee set directly into the p-trap. Bring the wash sink waste arm in the side of the baffle tee. I figure might as well have momentum and gravity on my side to help the disposal grindings through the half-pipe.

that is the best configuration you can have with 1 trap and a disposal

You will be better served if you use a long flanged tailpc at the disposal over to a waste tee under the other sink bowl w/flanged tailpc vert to the tee. Then the fixture trap below the waste connections.

This is a typewritten diagram of what I just said, wish I had a better keyboard.

As in all type-written 'drawings' I can't make heads or tales but what I
find is that the most direct path to the trap inlet from the disposer the
better, it usually means less chance of clogging.
