I found in code that you can have a stack of shared drain / vents on this page:
The International Code Council is proud to distribute a helpful tool — Methods of Venting Plumbing Fixtures and Traps in the 2021 International Plumbing Code: Installation, Flexibility and Opportunity for Savings —...
I don't see that you can do 3 together.
Are you allowed? Can they be offset? Would the Charlotte #PVC 00418 allow for a shower on the left, a toilet in the middle, a single vanity on the right and a shared vent up top? The left and right inlets don't look like sanitary tees. This will go straight down about 10 feet no curves to a horizontal drain that would feed into the septic tank. Another bathroom would do the same thing down to the same horizontal pipe about 32' away.
If I am not allowed to connect all 3 at the same location, would I be able to have the toilet and shower connect at the bottom and then the vanity connect higher up in the stack and share that vent?
Bathroom will be 8' x 5' shower, toilet, vanity left to right.
