To be more specific, every homeowner who has an irrigation system absolutely must know how to adjust the sprinkler heads when necessary. Being able to do so allows the homeowner to guarantee that the grass gets an equal coverage of water and that there is no overspray as a result of the procedure. Continue reading to learn how to make adjustments to typical sprinkler spray heads in addition to rotor heads made by the Signature and Hunter brands. Many homeowners are happy to discover that knowing how to adjust sprinkler heads is really more simpler than they had first anticipated, regardless of the particular kind or brand of sprinkler heads that they are using.

How to Adjust a Sprinkler Spray Head

There are a lot of different scenarios in which you could want knowledge on how to adjust a spray head. The most typical cause of this problem is that the spray heads are pointing in the wrong direction, spraying into sidewalks or pathways, or that your grass isn’t getting enough coverage.

To our relief, making adjustments to a spray head is, for the most part, a rather straightforward process. The spray head may typically be adjusted through a little screw located at the very top of the majority of spray nozzles. To get the results you want, you’ll need to take this adjustment screw and, using a Phillips head screwdriver, either turn it clockwise or anticlockwise. Turning the screw in the counterclockwise direction will lessen the amount of water pressure that is being applied to the nozzle, which should help if you are experiencing trouble with overspraying. Performing a turn in the anti-clockwise direction will have the opposite effect.

You can also move the screw to modify the direction of the spray on your grass, which will ensure that it receives an equal amount of water throughout the whole year. The following video provides instruction on how to properly adjust a spray head nozzle.

How to Adjust a Hunter Rotor Head

You will need a Hunter adjustment key in order to be able to raise or decrease your arc and vary the direction that your spray will go. If you are in need of a key, you may buy one from us here.

To make the arc of your Hunter rotor head more expansive, you will need to place the plastic key into the adjustment socket, which is located on the very top of each sprinkler head. This will allow you to make the rotor head spray more broadly. In a complete 360-degree rotation, turn the adjustment wrench in the clockwise direction. Each time you spin the wrench all the way around, the arc will be increased by an additional ninety degrees. You may continue doing this up to the point when you have completed a full arc of 360 degrees, at which time you will no longer be able to spin the wrench and you will hear a ratcheting sound.

Turning the adjustment wrench in the opposite direction of the clock will have the desired effect of shortening the arc. When you do this, the arc will be shortened by 90 degrees until it reaches either 40 or 50 degrees, depending on the model you have. This will continue until the minimum arc has been attained. When you are trying to avoid over-spray or when you want to prevent water from spraying on the sidewalks and pathways on your property, this may be something that you need to do.

It is highly recommended that you view the video that Hunter has provided below on how to properly tune their rotors.

How to Adjust a Signature Rotor Head

If the rotor head on your home irrigation system is made by the Signature brand, then the process of adjusting the spray will need a different series of procedures to be carried out. To adjust the arc and spray radius of these rotor heads, a one-of-a-kind system of click-set disks and memory rings is used. Because of this, the caps of each sprinkler head will need to be removed in order to get access to these microscopic pieces.

To be more specific, a new spray point may be established by adjusting the memory disk by utilizing the little plastic protrusions, which are also known as “collars.” If you want to expand the spray radius of a sprinkler head, then you will need to fully remove the black click-set disk and then manually adjust the sprinkler until the nozzle is directed in the middle of your target area. This will allow you to increase the spray radius.

After that, when you want to reinstall the black click-set disk, you may flip it upside down (so that the gray side is facing up) and adjust its collars to the appropriate angle of spray. This can be done before reinstalling the black click-set disk. This is wonderful for ensuring that you do not waste water (and make enemies out of your neighbors) by unnecessarily spraying sidewalks and pathways throughout the watering cycle. If you do this, you run the risk of making your neighbors angry.

On the other hand, if you aren’t getting even coverage from your Signature rotor sprinkler head, you can adjust the spray so that it reaches full-circle by simply leaving the black side of the click-set disk facing upwards and not adjusting any of the collars. This will cause the spray to reach the entire circumference of the sprinkler head. This is the standard adjustment that is advised to be made to sprinkler heads that are situated in the middle of your lawn and are not close to any paths.

As you can see, changing the sprinkler heads on spray-style sprinklers as well as rotor-style sprinklers is a lot simpler than you would have first imagined it would be. And with some time spent practicing, experimenting, and learning from your mistakes, you’ll be able to fine-tune the irrigation system in your house to ensure that your grass receives enough watering throughout the year while simultaneously minimizing overspray and wasting water. Because you are now aware of how to make adjustments to the sprinkler heads, you are able to have a bit more faith in the irrigation system.

How do I make my sprinkler heads rotate less?

You may alter the spray pattern of the sprinkler by using a screwdriver with a flat head to turn the adjustment screw that is located on the top of the nozzle. If you want the spray pattern to be wider, spin the screw so that it is facing the opposite direction of the clock. Turning the little screw counterclockwise will have the effect of decreasing it.

Why does my pulsating sprinkler get stuck?

Sprinkler heads are susceptible to being clogged when the water pressure is either too low or too high. When the water pressure falls below the permitted limitations, the sprinkler head may get stuck on one side of its arc or it may not move at all. Both of these outcomes are undesirable. If the water pressure is too high, the sprinkler may either cease working altogether or get stuck.

What tool do you use to adjust sprinkler heads?

Slotted screwdriver: Some sprinkler heads may be changed by using a narrow slotted (flat head) screwdriver, which is something that most people already have lying about their homes. Adjusting a Rain Bird sprinkler, for instance, often just requires the use of a slotted screwdriver, such as the one sold by Klein Tools under the brand name Flat Head Screwdriver.
