I'm trying to figure out the most efficient DWV for our back-to-back bathrooms. We're under IPC 2006. Does this iso look correct? I would be using a double fixture fitting for the back-to-back lavs. Can I take a common vent for both toilets off a wye between them? Would the bathtub be properly wet-vented off the lavs if it were within the required distance?
Also, I'm unsure about how to connect the bathtub drain/wet vent to the main drain. I read in a plumbing book, which I think was based on UPC, that you can't roll your wye above a 45 degree angle with a wet vent because the falling water might cut off the flow of air in the pipe. Is that correct? Thanks for your help.
