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
