my new well should produce 12-15gpm and i am considering a 3 phase motor with controller (goulds gs 1-1.5hp with balance-flow controller). the pressure tank is 4.5gallons. i should consider some light irrigation in the summertime as well but water is mainly being used for household usage, washer, dishwasher, showers, etc. 2 adults, no kids, a few horses in pasture and 4 dogs. my well is 130ft deep
