Why Replace Sprinkler Nozzles?

Replacing damaged or plugged sprinkler nozzles is essential for maintaining an efficient irrigation system. This guide will walk you through the process of replacing nozzles or installing new ones on pop-up heads.

Step 1: Access the Sprinkler Head

Begin by pulling the pop-up sprinkler head shaft up out of its resting place. A small screwdriver can be helpful to pry the sprinkler nozzle out. Note that it's spring-loaded, so you'll need to hold it up throughout the process.

Holding the Sprinkler Head

Hold the sprinkler nozzle up by putting pressure on the bottom of the shaft with your fingers. This will keep it extended while you work on it.

Step 2: Remove Old Nozzle

Unscrew and remove the nozzle or flush cap (on new heads, this cap allows you to flush debris before installing a nozzle). Also, remove the basket/screen. You may need a small screwdriver to help remove the basket.

Step 3: Select New Nozzle

Choose the proper sprinkler nozzle for replacement. Nozzles are rated by number, which relates to how far they throw water. For example, a 15 nozzle will throw water 12-15 feet, covering an area up to 30 feet wide. Consult manufacturer charts for specific model information.

Step 4: Install New Nozzle - Part 1

Insert the nozzle basket or prefilter into the sprinkler head.

Step 4: Install New Nozzle - Part 2

Screw on the new sprinkler nozzle securely.

Step 5: Adjust Nozzle Direction

If the sprinkler nozzle is on an edge of a zone (like along a sidewalk) and needs adjustment, grasp the sprinkler head shaft and twist it in the required direction. You may hear clicking sounds while turning the shaft; this is normal.

Adjusting Variable Arc Nozzles

For variable arc sprinkler nozzles, adjust the arc by twisting the ring on the collar or top of the sprinkler nozzle. The exact method may vary depending on the brand of nozzle you're using.

Step 6: Test and Finalize

Finally, test the sprinkler zone to ensure the new sprinkler nozzle is working correctly and adjusted properly for optimal coverage.
