Rain Bird is a sprinkler company that makes lawn sprinkler heads and systems. An installed sprinkler system in your lawn allows you to water the grass without thought or worry in most cases. However, if one of your sprinkler heads gets misaligned it may not spray in the correct direction. You can adjust the sprinkler head in a few simple steps.
Turn off your lawn sprinkler system.
Find the screw on top of the sprinkler head you want to adjust. Tighten the screw a few turns, clockwise, with the screwdriver to reduce the distance the sprinkler head sprays. Loosen, to increase spray, by turning the screw counterclockwise.
Adjust the direction the water sprays by firmly gripping the sprinkler head and turning the nozzle in the direction you want the water to spray. This is an effective way to keep sprinklers from watering sidewalks and streets instead of grass.
Pull up on the stem of a VAN, or variable arc nozzle, and turn it left or right to adjust how far it sprays. The numbers on the nozzle are how many feet the head will spray if turned to that number.
Turn on your sprinkler system to check the improvements. It may take a few tweaks to adjust the spray to desired levels and target areas.
