Planning on having my sump on the other side of the wall in a separate room and wondering if a 1 1/2” drain pipe with 1/4” per foot slope on a 6’ run would be sufficient for about 800-1,000gph? I can’t find a calculation for this. I know the pipe is rated for ~2100gph but not sure if slope plays a role in the total gph.
I’m probably overthinking this.
I’m trying to keep my sump at a comfortable height for maintenance ect.

Overthinking it. But would be better to have an additional emergency drain just in case.

it wont be a problem. you can lay it flat over the 6' run and it will be fine. I have a 30' run of 1 1/2" drain (herbie style) and drain around 1500 gph through it. My drop from overflow to sump is about 5' 6".
