Can overhead waste pipe be moved?
I have an old house on a septic system. The cast iron waste pipe runs diagonally across my basement, starting at ceiling height (about 7') and sloping down about 2' to its exit point, cutting off about a third of the basement. I know that the waste pipe has to have a certain slope, but can it have any bends? I'd like to move it to open up the space.
I'm thinking about adding a bulkhead entrance in that part of the basement (only possible place to put it), and possibly also move the interior basement stairs to that area, but unless the waste pipe can be moved, neither project would work because the pipe would be in the way.
If it can be moved, any idea how much it would cost (roughly)?
