FAQ
Why won’t my sprinkler zone turn on?
Start by confirming the controller is running the correct program and start time, then check the zone wire, solenoid resistance, and whether the valve opens manually at the bleed screw.
Why won’t my sprinkler system shut off?
A valve diaphragm may be stuck open, debris may be holding the valve open, or the controller may be continuously energizing the zone due to wiring shorts.
Why do multiple zones run at the same time?
This often points to wiring issues, a shared common wire problem, or a mechanical valve issue allowing cross-flow.
