To adjust sprinkler heads effectively, follow these general steps depending on the type of sprinkler head you have:

Adjusting Pop-Up Spray Sprinkler Heads

• Turn on your irrigation system so the sprinkler heads pop up.
• Locate the small radius adjustment screw on top of the nozzle.
• Use a flat-head screwdriver to turn the screw:
  • Clockwise to increase the spray radius (distance).
  • Counterclockwise to decrease the spray radius.
• To adjust the spray direction or arc, manually turn the sprinkler stem by hand or with pliers to aim the water where needed

Adjusting Rotor Sprinkler Heads

• Turn on the system and stand behind the rotor to avoid injury from water pressure.
• Rotate the rotor head all the way to the left to complete any ongoing cycle.
• Find the right stopping point by gently pushing the rotor head clockwise until it stops spraying.
• Adjust the arc by inserting the rotor adjustment tool or screwdriver into the adjustment slot:
  • Turn the tool counterclockwise to increase the arc (spray angle).
  • Turn it clockwise to decrease the arc.
• Adjust the spray radius by turning the small screw on top of the rotor:
  • Clockwise reduces the radius.
  • Counterclockwise increases the radius.
• Fine-tune the arc and radius while observing the spray pattern until it covers the desired area without overspray onto sidewalks or streets

Adjusting Impact Sprinkler Heads

• Adjust metal stops or tabs on the sprinkler to change the spray pattern and direction.
• Use pliers if needed to pinch and move the tabs left or right.
• Raise or lower the spray deflector on the nozzle to adjust the distance:
  • Lower deflector for shorter spray.
  • Raise deflector for longer spray

Tools You May Need

• Flat-head screwdriver (most common)
• Rotor adjustment tool or hex wrench (may come with your system)
• Pliers or vise grips (for tough adjustments)
• Sprinkler head lock tool (optional for removing heads)

Adjusting sprinkler heads yourself is straightforward with these tools and steps, helping ensure efficient water coverage and conservation on your lawn
