Newbie here. I searched but can't find the answer.
When I plumb my 4" bottom drain, what angle should I run the 4" PVC pipe underground before it reaches the pump?
1) Level from the bottom drain, then a 90 degree sweep up to the pump
2) Gradual slope underground to the pump
3) 45 degree directly to the pump
4) Something else entirely
I put on my kindergarten thinking cap and went to town with some crayons. Does this picture help explain my question?
