I'm kind of new to home improvement projects like this, so I am not sure what people mean when they say "pulled a permit". So, I'll give you the long-winded story:
I applied for a permit for room remodeling, which actually requires three separate permits (one each for: electrical, plumbing, and room remodeling). After I pass an electrical inspection (assuming that I do), then I'll have to deal with a "rough-in" plumbing inspection and then a final inspection.
I think that I could get into some trouble when I attempt to connect the vent lines from my new plumbing into the old, smaller waste vents. The main stack is cast iron, so I'm trying to avoid dealing with that as much as possible.
Anyhow, thank you very much for all of your help!
