Okay, To try to move water 30ft up hill for approx 600ft we purchased a Gould gt15 pump. We have a 2 inch pipe inlet and a 2 inch pipe outlet. The outlet pipe then goes the 600 feet in 2 inch poly pipe to refill a pond, but the pump now cavitates. We got the pump to stop cavitating by reducing the end of the pipe (end of the discharge pipe 600 feet away from pump) down to 3/4 spicket and into a 1/2 inch cloths washer hose, but then we only get 10gpm. Is there a better way to stop the cavation while keeping the volume high?
Thanks
Greg
