Hunter System: Controller Works But No Water—Check Valves and Main Shutoff

New Homeowner Can't Get Hunter System to Run: Valves or Main Shutoff?

Indoor Hunter controller works. Opened two in-ground "globes" (valve boxes), turned valve 1/4 turn per knob. No water. Hoses work. Can't find main shutoff.

Globe Valves Are Likely the Control Valves

The "globes" with knobs are the zone control valves. The knob is the flow control.

Proper Flow Control Adjustment

  1. Open flow control fully (counterclockwise).
  2. Close fully (clockwise), counting turns.
  3. Reopen half the turns.

Then Test Manually

Use the manual bleed (small screw/lever on valve) to open each valve. If water flows → valve works, controller wiring is next. If no water → main shutoff valve is closed somewhere upstream. Find it (often near water meter, backflow preventer, or pump).

Don't assume 1/4 turn is open—adjust properly.
