Small bathroom DWV

This is my 2nd floor bath. I'm hoping to do the following, but I wasn't sure if this fitting can be used. It is the 90 3x3x2 with the 2 coming in on the corner.

All fixtures are within 3 or 4 feet of each other. Thanks!

I quote from my copy of the Uniform Plumbing Code: "No ... side inlet quarter bend ... shall be
used as a drainage fitting ..."

Now where is the fun in that? Do they make WYEs that have a street bend type ending at the base? This is going to be tight.

Thank you for your reply!

Actually, in the vertical position it can indeed be used that way under everybody's code.

The inlet does NOT have a sweep, which would make it illegal under most codes, and since the shower does NOT have a vent, and it does not make any difference how CLOSE It is to another fixture.

I have a vent for the shower already, sorry it wasn't pictured. So if I WYE between the toilet and the drain it should be ok? Just abandon the 90 with the side inlet?

Thanks!

Yes, and they DO make street 'Y"s.
