snrub, how long of a run, and what size hose/pipe were you planning on using?
My runs are not all that long. Maybe 300 feet for the longest run. I have 3/4" black water pipe bought for the ground portion (but probably not enough yet) and 5/8 sinking for most of the in water portion.
I figure it is better to err on the larger side than the smaller. In my application it will be pretty easy to keep the hose running down hill from the pumps.
Where I was thinking of a long run is if I ever decided to aerate the old pond. It is maybe a quarter mile and would involve trenching under a small creek then up a hill. Not sure if I will ever do it or not. Not this year for sure. Already enough projects to keep me busy this spring and summer.
