Turn Off The Pump

You’ll need to turn off the water supply and power to the pump before making any adjustments. Make sure that the pump has been turned off and is not running before you start adjusting your lawn sprinkler.

If you don’t turn off your water and electricity, you could get injured or damage some of your sprinklers.

Watering a lawn effectively requires appropriate sprinkler heads, which also need to be adjusted correctly. Check out our detailed guide on how to adjust lawn sprinkler heads for tips and tricks to ensure your sprinklers are working correctly and your lawn is well-maintained.

Locate The Sprinkler Head

Locate the sprinkler head. The first step to adjusting a lawn sprinkler is locating the actual sprinkler head, which will be in the middle of your lawn.

 You can spot it thanks to its tall neck and circular base, both of which are typically green or black. The head should also be connected via a pipe to another piece (usually black) that is buried underground.

Proper maintenance of garden sprinklers is necessary to ensure they are working correctly and prevent any damage. Check out our guide on how to adjust garden sprinkler heads for tips on maintaining and adjusting your garden sprinklers and get the most out of your sprinkler system.

Remove The Sprinkler Cap And Screw

Remove the sprinkler cap and screw. You may need to use a screwdriver, but you may also find that the cap unscrews directly by hand. 

If it doesn’t, you’ll need to loosen the screw first. It’s important not to lose either the cap or its associated screw keep them in a safe place until you’re ready to replace them on your new sprinkler head!

Proper garden drainage is critical, and there are different methods to achieve this depending on your garden’s landscape. Check out our guide on how to add garden drainage to understand different ways to improve your garden’s drainage and prevent waterlogging.

Adjust The Arc Range Of Your Sprinkler Head

You can adjust the arc range of your sprinkler head. The “arc” is the distance from the center of the sprinkler head to the outer edge of its spray pattern.

The right-wing should be just wide enough to cover your desired area. If it’s too far and you end up watering more than you need, water will run off before it reaches plants that need it. 

On the other hand, if you set your arc too close and water only what’s in front of your lawn sprinkler head, some areas may not get enough moisture or nutrients.

Adjusting the Arc Range of Your Sprinkler Head

1. Locate the arc adjustment feature on your sprinkler head. This is typically a small lever or screw on top of the head.
2. Turn on the sprinkler system to test the current arc range. Use markers or flags to indicate where the water hits within the spray pattern.
3. Adjust the arc to your desired range by moving the lever or screw in the appropriate direction. Some sprinkler heads may require a special tool for adjustment.
4. Turn on the sprinkler system again to test the new arc range. Make further adjustments as needed until you achieve the desired coverage.
5. Once you’re satisfied with the arc range, turn off the system and replace any soil or sod that was removed during the adjustment process.

This table outlines the steps involved in adjusting the arc range of your sprinkler head. By following these steps, you can customize the arc distance to ensure optimal coverage of your lawn or garden.

Adjust The Spray Pattern

To adjust the spray pattern on your lawn sprinkler, follow these steps:

  • Hold the sprinkler head in one hand and use your other hand to move it around from side to side. The arc of motion should be sweeping; don’t just make small turns in one direction or another.
  • Adjust the arc range of the sprinkler head clockwise to increase its range, or counterclockwise to decrease its range

Place The Screw And Cap Back Into The Sprinkler

Now that you’ve extended the sprinkler and adjusted its height, make sure that everything is in order. Use your screwdriver to screw the cap back into place. 

It should be tight enough that it doesn’t come loose when you turn on the water, but not so tight as to make it impossible to remove again if needed. 

If everything feels good, test out your new sprinkler by turning on the valve at your hose bibb or faucet.

Placing the Screw and Cap Back into the Sprinkler

1. Locate the screw and cap that were removed from the sprinkler head.
2. Use your screwdriver to align the screw with the hole in the top of the sprinkler.
3. Slowly and carefully tighten the screw until it is securely in place.
4. Place the cap back over the screw and align it with the rest of the sprinkler head.
5. Use your screwdriver to attach the cap tightly to the rest of the sprinkler.
6. Turn on your sprinkler system to test the sprinkler head for proper operation.

This table outlines the steps involved in placing the screw and cap back into a sprinkler head after extending and adjusting the height of the sprinkler head. Following these steps will ensure that the sprinkler head is properly secured and won’t come loose during operation.

Test Your Sprinkler

After you have adjusted your sprinkler, it is important to test it. You can do this by walking around the yard and observing each sprinkler head. 

You should see water coming out of the top of each head. If not, then you may need to adjust your sprinkler again until you find a setting that works for all areas of your yard.

You should also test your sprinklers before leaving the house so that no one finds themselves standing in a dry patch of grass when they return home from work! 

Adjusting your sprinkler system is an easy way to ensure that everyone has access to evenly watered lawns all year round!
