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

hey thanks terry!
great resource for us "wreck-it-yourselfers"


: :
: : 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!
