Thank you for the reply. How can I open the system manually and how can I make sure the water is turned on? I guess I need to find the valve but I don't know where it is. Thanks!
I have Rainbird ESP-6TM Controller. The Sprinkler heads don't popout with water either in manual mode or in auto mode. The controller receives power but the output power is always 0 when I checked it with the voltmeter. Fuse is also good. I also used the spare fuse. Recently, my house got some T-storms as well as power interruptions. Any ideas? Thanks!
