Q.Irrigation and Watering Transplanted Trees
Regarding irrigation, my timer Rainbird has 36 stations on the panel. They connected 37 valves, one station hold 2 valves, and the timer does not respect the time to water. For example, it starts at 9 pm, but first station won’t start to 11 pm (2 hours behind). Is my timer panel burned out? Are the 2 valves in one station in the panel creating this problem?

This question would best be answered by the vendor who installed the irrigation system or sold you the system.
