Hello, first time poster here. I'm an HVAC professional; just dabbling in a little plumbing for my own bathroom and wanted to clarify a couple code items. I'm in Ohio.
This is a second floor bathroom I'm working on. Lav, tub, w.c. There's also a third floor bath above it, in which the whole bathroom group discharges down a 3" soil stack (6 dfu).
1. Can I tie the 2nd floor toilet into the 3" waste stack (from the third floor) using a sanitary tee? If so, do I need a vent between the toilet and the stack? Or must I use a wye?
2. If he answer is "yes" to the question above, can I use a san tee with a 2" side inlet to drain my lav and tub from the same bathroom group if the lav and tub are vented prior to entering the tee?
3. What horizontal bends can I make in the toilet lateral before the stack, both individually and cumulatively?
I have an ISO drawn, but it assumes I need a circuit vent for the toilet and that I'm discharging the 2" further down the stack with a wye. Thanks for your help.
