We have a backflow regulator that keeps going off when a certain zone comes on line. There is not a slope in the yard that would cause the water to drain out of the line. The zone beside the one in question is in the front yard also and has no problems when it comes on line. I understand the pressure differential from the inlet and outlet of the backflow regulator would cause the problem. We dont see any spots where water could be leaking on the discharge of the hunter valve or around the hunter rotors after the valve shuts off. You can manually close the discharge of the backflow regulator and slowly open it and the problem will go away. We are watering every other day so the line has time to go empty.
Thanks
