Adjusting the spray radius on your Hunter sprinkler is an essential task for maintaining an efficient irrigation system. By customizing the spray radius, you can ensure that your lawn and plants receive the right amount of water, preventing overwatering or underwatering. This article will guide you through the process of adjusting the spray radius on your Hunter sprinkler, so you can keep your landscape looking its best.
To begin, you’ll need to locate the radius reduction screw on your Hunter sprinkler, which is typically found on the top of the nozzle. This screw is responsible for controlling the distance the water spray reaches and can be adjusted to increase or decrease the radius as needed. Keep in mind that the radius is preset to the maximum distance for your specific nozzle, but you can reduce it by up to 25%.
Once you’ve identified the radius reduction screw, gather the necessary tools for making the adjustment, such as a small flathead screwdriver or the hex end of a Hunter wrench key. With these tools in hand, you’ll be able to make precise changes to your sprinkler’s spray radius, ensuring efficient water usage and a healthy landscape.

Adjusting Spray Radius
In this section, we will discuss how to adjust the spray radius on your Hunter sprinkler.
Locating the Adjustment Screw
First, locate the adjustment screw on your Hunter sprinkler. It can typically be found on the top of the nozzle. The adjustment screw is used to increase or decrease the spray radius.
Using the Radius Adjustment Tool
To adjust the spray radius, you will need a radius adjustment tool such as an Allen wrench.
- Find the raised arrow on top of the spray nozzle.
- Insert the Allen wrench into the hole next to the raised arrow.
Setting the Desired Radius
With the radius adjustment tool in place, you can now set the desired radius for your Hunter sprinkler:
- To decrease the spray radius: Turn the wrench clockwise.
- To increase the spray radius: Turn the wrench counter-clockwise.
Remember to make small adjustments and test the spray radius frequently to avoid over or under watering your lawn.
Troubleshooting Common Issues
Inconsistent Spray Pattern
Occasionally, you might encounter an inconsistent spray pattern from your Hunter sprinkler. To resolve this issue:
- Check and clean the filter – A clogged filter can cause inconsistent spray. Remove the sprinkler head, locate the filter, and clean it thoroughly.
- Inspect the nozzle – Ensure the nozzle is correctly installed and not damaged. Replace it if necessary to ensure a consistent spray pattern.
- Adjust the arc and radius – If the spray pattern doesn’t cover the desired area, use the Hunter wrench to adjust the arc and radius accordingly.
Over or Under Watering
Overwatering or underwatering can result from incorrect adjustments to your Hunter sprinkler. Follow these steps to address the issue:
- Inspect the spray head – Ensure it is properly functioning. Check for damage or clogs preventing an even water distribution.
- Adjust the arc and radius – Use the Hunter wrench to fine-tune the arc and radius of your sprinkler to ensure it covers the intended area.
- Program the watering schedule – Check the watering schedule settings on your irrigation controller to make sure the sprinkler is running for the correct duration and frequency.
By following these troubleshooting steps, you can ensure your Hunter sprinkler provides even and efficient watering to your landscape.
Sprinkler Maintenance and Optimization
Proper maintenance and optimization of your Hunter sprinkler system will help to keep your lawn looking its best. By performing periodic inspections and making seasonal adjustments, you can ensure that your sprinklers provide the right amount of water at the right time.
Periodic Inspection
It’s important to inspect your sprinkler system regularly to catch any issues early on. Follow these steps during inspections:
- Check for damage: Look for any cracked or broken sprinkler heads, as well as leaks or other signs of damage.
- Test spray patterns: Make sure that your sprinklers are providing even coverage and that there are no dry or overly saturated areas.
- Clean the filters: Sprinkler heads can become clogged over time, reducing their effectiveness. To clean the filter, turn off the water supply, unscrew the nozzle, and remove the filter. Rinse it thoroughly and reinstall it.
- Flush the system: Occasionally, dirt and debris can build up within your sprinkler system. Flushing the system by briefly running water through each zone will help to clear out any obstructions.
Seasonal Adjustments
As the seasons change, so do the watering needs of your lawn. Here are some tips for making the necessary adjustments:
- Adjust the spray radius: To decrease the spray radius on your Hunter sprinkler, hold the top of the nozzle edge and turn the screw in a clockwise direction using a small flathead screwdriver. To increase the spray radius, turn the wrench counter-clockwise.
- Monitor weather changes: Be mindful of rainfall or temperature changes, and adjust your watering schedule accordingly. This will help to prevent over or under-watering.
- Winterize your system: If you live in an area with cold winters, make sure to prepare your sprinkler system for freezing temperatures. This includes draining the water from the pipes and turning off the water supply to the system.
By performing regular maintenance and making seasonal adjustments, you can keep your Hunter sprinkler system running optimally and maintain a healthy, attractive lawn.
