I have 4 acres of yard with an irrigation system. I pump 50 feet uphill and then I have 900 feet to the front of my yard. Overall I calculate 100 feet of head. This puts at 40 gallons a minute it is so much better than the expensive pumps that I’ve been per purchasing previously. Every few years they would go out and I’d be out $1200. This works fantastic my only complaint is that the wiring to the motor could be a larger gauge. Other than that this is a great motor pump combination and a fantastic price. I bought three so that I would have spares. I figure even if they only last year I’ll still be far ahead. So far I have no reason to believe they won’t last too much longer than that.
