I am getting about 20 feet of lift at 9000 gallons per hour with two sump pumps into a 2" line. I didn't notice the power on the hydro bill and they have their own floats that turn them on and off when there is water there. Works great and I don't have to worry about them at all.
There is about 200 acres of field tile that drains to this creek to keep my .75 acre pond full.
Cheers Don.
