Hi all, my first time posting so I do apologize ahead of time if I mess up and make things more complicated then they should be. lol

I plan on moving my bathroom from one side of my house to the other side. I do have a couple questions.

- 3" abs running at a 1/4 inch per foot drop(in crawl space) from new toilet,sink,shower to existing stack (estimated distance will be approx. 35 feet). Is this possible ?

- if this is possible I have a 3inch vent at the stack end now I would leave that there and have all fixtures in new bathroom tied into a 2" that I have fed up through the roof.
