In my basement my 4" main cast iron pipe comes into the house about 2'
off the floor 10' from the corner. It then turns 90 degrees to get to
the side wall, then proceeds along the side wall to the back of the
house. Another 90 to run along the back wall 10' to catch the drains
from the kitchen and bathrooms.
Since I can have a vertical drop in the wall to get to the basement is
there any reason why I can't take the existing drain in the basement
and raise it up to the ceiling then drop it the 5' needed to get back
to the existing hole in the foundation?
The only issue I can see is I would have a 5' vertical drop right
before the house trap. The house trap is about 6' away from the
