Hello all - Fantastic forum you have here. One of the best communities I've come across in some time!
I am remodeling our 2nd story bathroom and am having some trouble with figuring out the layout in such a tight space. There are no other bathroom groups on this drainage stack/vent. I have recreated the layout of DWV system from the prior setup and will try to explain the fixtures I have in place now.
The prior system used a 90 degree elbow with a side-inlet to drain the whole bathroom group. The toilet was connected to the elbow and the bathtub/lav were connected to the side-inlet via a wye which was wet-vented with the lav. I live in Ohio and I believe the use of an elbow with a side-inlet is permissible in this instance.
706.4 Heel-or side-inlet quarter bends. Heel-inlet quarter bends shall be an acceptable means of connection, except where the quarter bend serves a water closet. A low-heel inlet shall not be used as a wet-vented connection. Side-inlet quarter bends shall be an acceptable means of connection for drainage, wet venting and stack venting arrangements.
I will be using 2" plumbing for the shower and lav drain/vent and 3" for the toilet. I would prefer to take the shower drain on the shortest possible route as it will require drilling through some floor joists. My main problem is determining the fittings that I can use in such a small space to connect everything to the main stack while keeping it horizontally wet vented in a proper fashion.
I hope I have presented everything in a logical manner. Any advice would be greatly appreciated!
