Rain Bird pop-up sprinklers sit slightly below the lawn's surface so you can mow over them without damaging them. Even though the sprinklers are low maintenance, from time to time you need to adjust spray heads to compensate for changing watering patterns or to fix pop-up sprinklers that get dislodged if someone steps on them. The process is simple and it takes just a few minutes.


Step 1

Pull the Rain Bird sprinkler head out of the ground. Let it snap back into place. If there is something restricting the action, such as grass or other debris, remove it.

Step 2

Turn the spray head to adjust the direction of the spray. On some models you may need to twist the collar that surrounds the spray head to make the adjustment. Some models have an adjustment screw that you turn. Turn the water on to the system to ensure the spray is flowing as you want. Repeat as necessary to fine tune the direction.


Step 3

Turn the flow rate screw on top of the sprinkler nozzle clockwise to reduce the flow rate of the sprinkler head. A fully tightened screw reduces the rate 25 percent. Turn the screw counterclockwise to increase the throw of the sprinkler head. Attach a diffuser control flap to the sprinkler head if you need to reduce the throw even more.


Always check that your sprinkler system has an adequate supply of water before adjusting the sprinkler heads.

Clean the sprinkler head if you can’t set it properly. Use a screwdriver to remove the screw holding the nozzle in position. Pull out the nozzle and its screen. Turn water on to the sprinkler head to flush the line. Clean debris from the screen. Replace the screen and tighten the nozzle head back into position.


Do not use lubricants of any kind on your Rain Bird sprinklers.
