In response to Re: adding second 3-4" stack

: I am adding a second bathroom to, yes, a (gulp) one bathroom house.
: The new stack is approximately 17 feet from the existing stack.

: My question is:
: Is it possible to run the new stack vertically from the second floor
: through the first and into the crawl space,
: AND THEN LATERALLY over this distance?

Yes, Terry

: And if so, should I use a 1/4" per foot, 1/8" per foot, or GREATER slope
: to ensure proper drainage?

1/4" per foot or more is UPC code. Terry

: I have 2 feet of vertical space (across the lateral 17 feet) to work with.

Sounds like plenty. You are only dropping 4-1/4" in that distance. Terry

: Did I mention I have to cut an iron stack in a 3 foot high crawl space :)

The cast iron stack can be cut with a saw blade, a sawzal works fine, or a cast iron cutter which you can rent. Terry
: Any suggestions would be greatly appreciated!
