Good Afternoon,

I'm new to plumbing and have hit my first snag. I'm working in a tight space between 6" joists and I'm trying to figure out how to connect some ABS drain lines in a manner that will pass code.

My first question is whether it would be within code (or advisable) to connect a 45 deg street into the end of a long sweep going back the other direction, almost creating an S-curve.

My second question is whether any manufacturer makes a 3x2x3 wye. The branch of the wye is always the reduced size in everything I come across.

Thanks so much for the help. Other posts on this forum have been incredibly helpful.

if you mean create a 135 deg turn in a drain? well, i wouldn't..
as for the "Y" in question, could a 3 x 2 bushing in the end of a 3 inch "Y" do it?

Not a 135 degree turn, a 90, then back 45 the other direction.

Unfortunately, with my space constraints, a typical 3x3x3 wye with a reducing bushing is too big for the space. Unless someone knows of a manufacturer of special short wyes. I'm working in between joists at a tough angle.

Thanks,
Steve

Usually, in that situation, a 45 without the 90 would do the same job.

"T" type fittings are always specified as RUN-RUN-BULL

so you are looking for a 3(run) x 2(run) x 3(bull/branch) "Y" fitting

no such animal available for 1 piece purchase

you can use a 'flush'/internal 3x2 bushing on a conventional Y

(just cut off the hex 'shoulder' after gluing in if necessary - you will then have a 3x2x3 with the exact dimensions of a 3x3x3)

The bushings at my supply house are flush without the hex shoulder. You do want to check the direction before you glue them in, because they do have a stop on the bottom.
