We actually have pumped just a couple of days ago. I pump from a pond that is about 800 feet from the tank. Another pump pressurizes the water from the tank to the rather massive sprinkler system. Love it!
I got to be one of the early testers (Thanks guys!) and have been running for over 6 months without a hiccup. Move from the rain catchment up to the upper tank where I can flow it down into 4 troughs on either side of the ridge. Nice little pump. Happy chugging away all day.
