Identify Sprinkler Components
The Rainbird 1800 sprinkler headhas a few key parts to know. The spray nozzlecontrols where water sprays. Different nozzles create different spray shapes.
The adjustment screwchanges the spray distance. Turning it left or right changes how far water goes.
The deflector shieldhelps shape the water flow. It stops water from spraying too far or in the wrong direction.
The pop-up risermoves up when watering and down when off. It hides the sprinkler when not in use.
Knowing these parts helps adjust the sprinkler for your garden’s needs.
Shut Off Water Supply
Turning off the water supplyis crucial before adjustments. Locate the main valveto stop the flow. It’s usually near the water meter or in the basement. Turn the valve clockwise to shut the water off. Ensure no water flows from the sprinkler heads. This prevents accidents or water wastage. After adjusting, turn the valve counterclockwise to restore water flow. Always check for leaks after restoring the water supply. This keeps your system working efficiently.
Adjust Spray Distance
Adjusting the spray distancecontrols how far water reaches your plants. Start by finding the small screwon top of the sprinkler head. Turn this screw clockwiseto reducethe spray distance. Turn it counterclockwiseto increasethe distance.
Make small turns and test the spray after each change. This helps avoid over or under watering. Keep adjusting until the water covers the needed area without wasting it.

Make small adjustments until the spray fits your garden’s shape.
Change Spray Pattern
To change the spray patternof a Rainbird 1800 sprinkler head, start by removing the spray nozzle. You can do this by twisting it counterclockwiseand lifting it off gently. Choose a new nozzle with the desired spray patternfrom the available options.
Before placing the new nozzle, check the spray arc adjustment ringon the sprinkler head. This ring controls the angle of the spray. Turn it clockwiseto reduce the spray arc or counterclockwiseto increase it.
After adjusting the ring, attach the new nozzleby pressing it onto the sprinkler head and twisting it clockwiseuntil it locks in place. Finally, test the sprinkler to confirm the spray pattern fits your lawn’s needs.
