Can I extend my sump pump outlet and dig it down in the ground?
There really aren't any hard-and-fast rules here as long as you don't work the pump too hard. Plenty of homes in my area have sump lines running all the way to the street gutter at 100 feet or more. You're right that you want to minimize bends, but a few won't hurt. The critical point is that the pipe is large enough. If you're talking about standard 1-1/4&quot; pipe you're fine. Smooth-wall rigid pipe is best.
