For maximum efficiency ensures even water distribution and prevents waste. Follow these steps for optimal performance:
1. Identify the Sprinkler Model
Different brands (Hunter, Rain Bird, Toro) have unique adjustment methods, so check the manufacturer’s manual if needed.
2. Adjust the Spray Pattern (Arc)
· Locate the Adjustment Screw: Most sprinklers have a screw at the top near the nozzle.
· Use a Special Key or Flathead Screwdriver:
· Increase the arc: Turn clockwise.
· Decrease the arc: Turn counterclockwise.
· Common Arc Range: Most models adjust between 40° to 360°.
· Check Coverage: Ensure overlap with adjacent sprinklers for uniform watering.
3. Set the Spray Distance (Radius)
· Find the Radius Adjustment Screw (near the nozzle).
· Use a Screwdriver:
· Turn clockwise to decrease the throw.
· Turn counterclockwise to increase it.
· Avoid Overspray: Adjust to prevent water from hitting sidewalks, driveways, or buildings.
4. Align the Starting Position
Manually Rotate the Head: Turn the sprinkler head to the fixed left stop.
Adjust the Right Stop: If needed, rotate the head clockwise to set the new stopping point.
5. Check Water Pressure
· Ideal Pressure: 30–50 PSI for most gear-driven sprinklers.
· Too High? Use a pressure regulator.
· Too Low? Check for clogs or leaks in the system.
6. Inspect for Clogs or Debris
· Remove the nozzle and flush the system if water flow seems uneven.
· Clean or replace nozzles as needed.
7. Run a Test Cycle
· Observe spray patterns and make final tweaks.
· Adjust sprinkler run time based on soil type and weather.
