A no flow alert means that the flow has dropped below the No Flow Threshold.
Possible Causes:
- The solenoid plunger is not lifting to allow the valve to open
- The master valve is not opening if in use
- The pump start is not being activated
- A gate valve or isolation valve in the mainline has been closed
When this type of alert occurs, the controller will stop irrigation on the station and raise a No Flow alert. It will then move onto the next station in the scheduled sequence. If three consecutive stations have No Flow alerts, the controller stops irrigation.
Possible Fixes:
- Bleed the corresponding valve manually to determine if water pressure exists
- Verify the Pump Start is operating correctly
- Locate and open any closed gate valves
