How Do I Adjust My Rainbird Sprinkler Heads?

Adjusting a Rain Bird sprinkler head requires a flat-head screwdriver, which is used to adjust the arc pattern. Homeowners can turn the screw clockwise to increase the range of the arc or counterclockwise to decrease it. The rotation of the arc is also adjustable from a 40- to 360-degree angle.

When making adjustments to a Rain Bird sprinkler head while it’s in use, only turn the screw in the direction that the Rain Bird sprinkler is already moving. Trying to adjust the arc against the direction it is moving may cause damage to the sprinkler by stripping the gears. Adjustments against the direction in which it is moving should only be done when the Rain Bird sprinkler is turned off.

Rain Bird claims that its sprinklers are some of the best in the industry because of how they are designed. For example, water often pools around sprinklers that are installed at the bottom of hills. This causes those areas of a yard to grow fungus. Some Rain Bird sprinklers, including the 3500 Rotors and 1800 Sprays, have a Seal-A-Matic Check Valve that helps eliminate puddling around the base. Homeowners can also use Rain Bird Rotary Nozzles, which are specially designed nozzles that reduce the rate of water flow, allowing for sufficient soak-in time.
