How To Adjust A Sprinkler Head Hunter

Hunter sprinkler heads are a popular choice for homeowners and landscapers alike. They are known for their durability, reliability, and ease of adjustment. If you need to adjust the spray pattern or coverage area of your Hunter sprinkler heads, it is a relatively simple process that can be completed in a few minutes.

Before you begin, you will need to gather a few tools. You will need a flathead screwdriver, a Phillips head screwdriver, and a pair of pliers. You may also want to wear gloves to protect your hands from dirt and debris. Once you have gathered your tools, you can begin the adjustment process.

The first step is to locate the adjustment screw on the sprinkler head. The adjustment screw is typically located on the top of the sprinkler head, and it is usually covered by a small cap. Use the flathead screwdriver to remove the cap. Once the cap is removed, you will see the adjustment screw. Use the Phillips head screwdriver to turn the adjustment screw clockwise to increase the spray distance or counterclockwise to decrease the spray distance. Make small adjustments until you achieve the desired spray pattern and coverage area. Once you have made the adjustments, replace the cap and tighten it securely.

Fixing Side Spray

Fixing a side spray is a relatively simple task that can be completed in a few steps. First, turn off the water supply to the sprinkler head. Next, use a flathead screwdriver to remove the nozzle cap. Then, grip the nozzle body with a pair of pliers and gently pull it straight up and out.

Wipe any debris from the nozzle body and inspect the O-ring for damage. If the O-ring is damaged, it will need to be replaced. Apply a small amount of lubricant to the new O-ring and insert it into the groove on the nozzle body.

Next, insert the nozzle body back into the sprinkler head and tighten it into place with the pliers. Be careful not to overtighten the nozzle body, as this can damage the sprinkler head.

Finally, replace the nozzle cap and turn on the water supply. Check for leaks and adjust the nozzle as necessary to ensure proper coverage.

Safety Precautions for Sprinkler Adjustment

1. Wear protective gear

Safety glasses, gloves, and closed-toe shoes are essential to protect yourself from any debris or water that may come into contact with your eyes, skin, or feet.

2. Turn off the water supply

Locate the main water shut-off valve and close it completely to prevent water from spraying while you adjust the sprinkler head.

3. Check the pressure

Using a pressure gauge, ensure that the water pressure in your irrigation system is within the recommended range for the specific sprinkler head you are adjusting.

4. Clear the area around the sprinkler

Remove any obstacles, such as grass clippings, leaves, or debris, from around the sprinkler head to allow for proper access and visibility.

5. Inspect the sprinkler head

Examine the sprinkler head for any signs of damage or wear that could affect its performance. Look for cracks, broken nozzles, or clogged openings.

6. Protect electrical components

If you are adjusting an electric sprinkler head, ensure that the wires are not exposed or damaged. Use electrical tape or a waterproof sealant to protect them from moisture.

7. Use the correct tools

Select the appropriate tools, such as an Allen wrench or screwdriver, to adjust the sprinkler head according to the manufacturer’s instructions.

8. Avoid overtightening

When tightening the adjustment screws or bolts, do so gently to prevent damage to the sprinkler head or its components.

9. Test the adjustment

Once you have completed the adjustment, turn the water supply back on and observe how the sprinkler head operates. Make any necessary fine-tuning until you achieve the desired coverage and throw.

10. Monitor the system regularly

After making adjustments, continue to monitor your irrigation system regularly to ensure that the sprinkler heads are functioning properly and providing adequate coverage to your lawn or landscape.
