Overhead sewer conversion project. Attached pics of the plan and looking to get feedback. Some of this routing isn't perfect but this is a retrofit and I wasn't planning on touching some parts of this to tie together.
Background: Overhead sewer conversion to prevent backup from floor drains into basement. City problem not an issue with my main.. the whole neighborhoods basements flooded and want a permanent solution.
-Existing stack would be severed at the drop to the basement and basement bathroom venting routed around back to the stack. (Some of this existing venting is currently not correct and can be fixed while doing this too).
-Drain from 1st floor bathroom diverted to the overhead line with tie ins from kitchen.
-1st floor bathroom horizontal branch need to offset downward (vertical w/ 90s will result in too low of a overhead line - 45s to offset the horizontal down and hug the ceiling at exit of the wall.).
-Basement fixtures already tied into existing main - divert existing main to pit.
-Pit pumps up to overhead line with a new vent for the pit added at front of house to avoid running vent all the way back to stack.
Feedback? How does this look? (Plan, fitting choice, cleanouts, etc). Anything anyone would do differently?
