Thanks for the input. I am on level ground, I have a water tank 8 ft dia by 15 feet tall, so I can gain 15 ft head. When it is full that is enough elevation head (pressure about 6 psi) to make a sprinkler produce a 5 ft circle, maybe. I need that pump that can boost to 40-60 psi, and produce at least 8 gpm, and run on DC.
