How would you go about dropping a main 4” sewer line 10-12” in a short run? Short run as of now is 8-10’. All under slab.
Is there a min drop ( change of direction)with out having a clean out?
I know greater than 45 degrees you would need one for a change in direction.
I’m thinking of using two long sweep 90 into one another make the drop and save on the digging . After this step down, this will keep the vertical rise on drain pipes to 12” or so under finished slab height. Is there a max vertical rise on pipe after the trap so the momentum of flow won’t drain trap?
Or would you 45 it ?
