I can't wrap my mind around how to tie the discharge of a laundry sink sump into existing plumbing.
I have come to the conclusion that the sump chamber needs to vent through the roof.
What I am having a hard time with is figuring if the discharge necessitates its own vent or do i need to make any changes to the existing drain's vent.
Here is a diagram I hope makes sense:
The diagram may not make it clear that the sink in the basement must use a pump.
Does this look right? Can it be done this way? Is there a better way?
Will the pump force water up the kitchen sink drain? Can I put a check valve above where I cut in to prevent this, or will this wreck the venting?
Thanks for looking!
