Hello all,
Currently remodeling and replacing all plumbing (failing) in a 1945 ranch home in South Dakota (UPC). Bathrooms are stacked on top of each other, and will have the exact same layout almost to the inch. We chose an in-wall toilet for the upstairs to meet clearances code.
My question is what is considered the trap-arm for an in-wall toilet? I have attached two models, one with dry vents. The other with wet vents. But, I'm pretty sure I have broken the rules concerning the upstairs toilet trap arm by running the upstairs lavatory waste through it. This option, though, would give me more options for plumbing the downstairs and ultimately save some elevation below the poured concrete floor.
Showers, kitchen and utility room are all serviced by another vent through the roof on the opposite wall.
If you catch anything else, I would love to know.
