Customer called for an after hours emergency shutoff, a zone came on by itself and had broken heads and was flooding the yard. A neighbor turned off the controller before I arrived, the controller is old and the dial doesn’t work, time is wrong, likely ran according to program. I disconnected the common wire and closed the backflow. Sent customer an estimate to replace controller, customer will call the office on Monday to schedule an appointment, they are overdue for a system inspection.
