Preparing The Sprinkler
Turn off the main water supply to stop the sprinkler. This helps prevent water flow while adjusting the sprinkler. Make sure no water sprays out during cleaning or fixing.

Adjusting Spray Distance
To change the spray distanceof your Rainbird 42Sa, find the adjustment screwon the top. Turning this screw changes how far the water sprays. Turn it clockwise to make the spray shorter. Turn it counterclockwise to make the spray reach farther. Always turn the screw gently to avoid damage.
Using The Adjustment Screw
The adjustment screwis a small, round screw on top. Use a flathead screwdriver to turn it. Be careful not to tighten it too much. Adjust slowly to get the right spray distance. This helps keep your lawn healthy and green.
Testing Spray Radius
After adjusting, test the spray radius. Turn on the sprinkler and watch how far the water goes. Walk around to see if the whole area is covered. If needed, adjust the screw again. Check the radius often to ensure even watering.
Setting The Spray Pattern
Adjust the left and right arcby turning the screw on the sprinkler head. This controls how far the water sprays on each side. Turning it clockwise will reduce the spray angle, while turning it counterclockwise will increase it. Make small turns to avoid over-adjusting.
The Rainbird 42Sa can spray in full circleor partial circlemodes. For a full circle, the sprinkler will rotate 360 degrees. For a partial circle, you can set the start and stop points to cover a smaller area.
| Spray Pattern | Description |
|---|---|
| Full Circle | Sprays water all around, 360 degrees. |
| Partial Circle | Sprays water in a set arc less than 360 degrees. |
Controlling Spray Height
Adjusting the spray height controls how far water reaches. To raise the pop-up, turn the adjustment screw clockwise. This lifts the sprinkler head, allowing water to spray higher. Be careful not to raise it too much to avoid damage.
To lower the pop-up, turn the screw counterclockwise. This brings the sprinkler head closer to the ground. Lower height helps water plants without wasting water on sidewalks or walls.
- Use a flat-head screwdriver for adjustments
- Turn slowly to avoid breaking parts
- Test spray after each change
- Adjust both sides evenly if needed
Troubleshooting Common Issues
Uneven coverageoften happens when sprinkler heads are blocked or dirty. Clear any dirt or debris from the nozzles. Check if the heads are damaged or not popping up fully. Adjust the spray pattern by turning the adjustment screw on the top of the head. Make sure each head is aimed correctly to cover the desired area without overlapping too much.
Water pressure problemscan cause poor sprinkler performance. Low pressure might be due to leaks or closed valves. Check for leaks in hoses or pipes and repair them. Make sure all valves are fully open. High pressure can cause misting and uneven watering. Use a pressure regulator or install a pressure control valve to keep pressure steady.
