3/4in. sump line
 

Is anyone else limited to a single 3/4in. flow line to their sump. I will have a back up, so ok there but wondering how much flow a single 3/4 can handle. Im guess around 350gph.

Doug they say a 3/4" can handle 750gph but I am saying No way maybe or pressure rated thou. I would guess and say 500

Yea seems high to me Mike. Thats just the drain line to, so just downflow and about a 6ft horizontal run into the other room.
