I'm roughing in a new lav and toilet that are about 3' apart and I have a question about venting.
The toilet is to be roughed in at 12" and is 15" from the side wall. I want to install a 3"x3"x2" wye directly under the closet flange so that the 2" arm extends back to the wall (through a 2"x12" floor joist) and ties into the 2" vent stack (using a 45 elbow) for the lav that is wet vented. The bottom 3" connector of the wye will connect to a closet bend and travel about 18" and connect to the main waste line with another clost bend. This would then be the drain for the toilet and the lav.
I know the 45 elbow has to be above the center line of the 3" wye. Is this configuration OK or is there another fitting that I can use instead of the 3"x3"x2" wye? As I said, the entire connection is right up against the 2"x12" floor joist so things are a little tight. Thanks for the help.
