Why won't my irrigation system turn on automatically?

Almost always a programming issue. Power outages and dead backup batteries wipe stored schedules. Check your controller screen, replace the battery if needed, and re-enter your zone times. Also confirm no rain sensor or manual rain delay is overriding the program.

How do I tell if an irrigation solenoid valve is broken?

Run each zone manually from the controller. If one zone stays dead while the rest work, that zone's solenoid has likely failed. A technician can confirm with a multimeter test on the valve wiring — a healthy solenoid reads between 20 and 60 ohms.
