I have a Toro system, 10 zones, each with 4 Super 700 rotors, fed from a well. My pump does not run continuously as it should while watering, and my well man says I should try changing nozzles, so that more water is applied and the tank pressure does not build up enough to cycle the pump off. All nozzles are now 3.0 gpm. Does increasing to 4.5 gpm or even higher sound like a good fix?
