A beautiful lawn is one of the most outstanding features of a garden. But simply turning on the sprinkler system won’t help if the grass is not getting adequate water coverage or if all the water is spraying on the sidewalk.
So what can you do to make sure the grass gets the right amount of water to thrive?
One solution is to adjust your sprinkler heads to ensure even sprinkler spray. Fortunately, adjusting sprinkler heads is not a complicated task.
Your lawns watering needs are not uniform. For one, an area of your yard in direct sunlight will need more water than a shaded area. Secondly, some parts of the yard may not drain as well as the others, and they’ll need less water.
That’s why you need to adjust sprinkler heads to ensure that they distribute the appropriate amount of water on all the different areas of the lawn.
You may also need to adjust the head periodically as the weather changes — to make sure the water spray pattern covers your lawn adequately.
The first step in adjusting your sprinkler heads is to identify the types of sprinklers you have in your system. Each different sprinkler head will need to be adjusted differently.
There are three main types of sprinkler heads:
|Type of Sprinkler Head||Movement of Sprinkler Head||Spray Pattern|
|Gear-Driven Rotor||Rotates back and forth||Single water stream|
|Pop-Up Sprinklers||Pops up but doesn’t turn when spraying.||Circular spray|
|Impact or Multi-Trajectory Sprinkler||Sprays in different directions||Multi-trajectory stream|
Identify the areas of your lawn that need watering adjustments. Look out for areas with brown or withered-looking grass. The areas with browner grass will need a larger stream of water.
Also, check if there are any soaked or swampy-looking areas; those will require less water.
Once you’ve determined the types of sprinklers in your yard, it is time to find the tools for the job.
Here are the tools you’ll need depending on the spray head:
Pro Tip: Manufacturers usually sell adjustment tools that work best for their own sprinkler heads. For example, If you have a Hunter-manufactured sprinkler system, get a Hunter adjustment tool. The same goes for making adjustments to a Rain Bird irrigation system.
Head on over to the Sprinkler Supply Store to get the proper adjustment tools for your sprinklers.
Now that you have everything you need, you’re ready to start adjusting your sprinkler heads. Here’s the step-by-step process for adjusting each type of sprinkler head.
You can follow the same process on all Hunter and Rain Bird rotors. However, some Toro rotors have a fixed left-hand stop, not the fixed right mentioned above.
Pro-Tip: Use a nozzle insertion collar (pictured below) with your adjustment tool. The collar holds the spring-loaded head to make it easier for you to work on the nozzles.

Impact sprinklers don’t usually require much to adjust the spray and arc. You can adjust impact heads in a single-step process. All you have to do is rotate the head to increase or decrease the arc.
Turn the head clockwise to increase the arc or counterclockwise if you want to reduce the arc. Use an adjustment ring (pictured below) to get a better grip on the nozzle.
Keep the water running while you adjust the spray and arc. This will help you see if you have adjusted the sprinklers to your required specifications without frequently starting and stopping the water flow. Some sprinklers can only be adjusted while they are in motion.
It’s also important to ensure that each irrigation head sprays over to the next in every direction for full coverage.
