Rotary/Impact Sprinklers: Spray water in a circular pattern, often used for large areas.
Fixed Spray Heads: Release water in a fixed (fan-shaped) or circular pattern.
Drip/Emitter Systems: Deliver water directly to plant roots, requiring less adjustment.
Tools needed:
Adjustable wrench or pliers
Screw driver (flathead or Phillips, depending on the model)
Garden gloves (to protect hands from dirt or sharp edges)
Safety tips:
Turn off the water supply to the sprinkler system before adjusting.
Avoid working during peak sunlight to prevent skin irritation or overheating.
Most rotary sprinklers have a central screw or dial on the top that controls the spray arc (e.g., 90°, 180°, or full circle).
A side screw or lever may adjust the water throw distance.
Turning clockwise usually narrows the arc (e.g., from full circle to a partial spray).
Turning counterclockwise widens the arc.
Use a screwdriver to turn the central screw:
Some models have notches or markers to indicate the desired angle.
Tightening (clockwise) reduces the distance (e.g., to avoid spraying sidewalks or walls).
Loosening (counterclockwise) increases the distance, but ensure it doesn’t overshoot the target area.
Turn the side screw or lever:
Turn on the water supply briefly to check the spray pattern.
If water hits unintended areas (e.g., buildings or driveways), readjust the arc or distance.
Fixed heads often have a removable nozzle or a built-in adjustment tab.
The nozzle shape (e.g., circular, rectangular) determines the spray pattern.
Gently twist or tilt the head upward or downward to direct water toward dry spots in the lawn.
Use pliers to hold the base steady while adjusting the head if it’s stuck.
If water pressure is low, remove the nozzle (twist counterclockwise) and rinse out debris (e.g., dirt, sand).
Replace the nozzle if it’s damaged or worn out.
Each drip emitter may have a small flow control valve or knob.
Turn the valve clockwise to reduce water flow (e.g., for small plants).
Turn counterclockwise to increase flow (e.g., for large shrubs or trees).
| Issue | Possible Cause | Solution |
|---|---|---|
| Water spraying too far | Throw distance setting is too high | Tighten the side screw to reduce the spray range. |
| Inconsistent spray pattern | Clogged nozzle or misaligned head | Clean the nozzle, realign the head, or replace damaged parts. |
| No water coming out | Valve is closed or pipes are blocked | Check the main water valve and flush the system to remove blockages. |
| Head won’t rotate | Debris in the mechanism or rust | Disassemble the head, clean it, and apply silicone lubricant (avoid oil, which can damage seals). |
Regular Maintenance: Inspect sprinkler heads quarterly for damage, especially after mowing or landscaping.
Match to Landscape: Adjust heads to avoid spraying against walls, fences, or paved areas, which wastes water.
Consider Seasonal Changes: In dry seasons, you may need to increase water flow slightly; in rainy seasons, reduce it to prevent overwatering.
Use a Pressure Gauge: If your system has low pressure, check the water pressure at the main valve and adjust accordingly (ideal pressure is 40–60 PSI for most residential systems).
