Situation is 1830 brownstone construction. 4" cast iron vent / stack basement to attic with 3 toilets emptying into it. Now I know the code says don't do this, each should have a seperate vent, but it's been running fine for almost 2 centuries. I just finished replacing everything with PVC as the cast iron was disintegrating. Naturally adding 2 extra 3" vents/ stacks wasn't happening so it went back the same way.
Is this just one of those areas where the code is overly cautious? Anyone have videos of testing this scenario? Would love to see this modeled in real life with clear pipe.
