3. Setup and Installation

Proper installation is crucial for the efficient operation of your Rain Bird 1806 sprinkler body. Follow these general steps:

1. Prepare the Trench: Dig a trench to the desired depth, ensuring it is level and free of obstructions. The sprinkler body should be installed flush with the ground surface when retracted.
2. Connect to Lateral Line: Connect the 6-inch inlet connection of the sprinkler body to the irrigation lateral line using appropriate fittings. Ensure all connections are watertight.
3. Install Nozzle: Remove the pre-installed orange 1800 Pop-Top flush plug. Select the desired Rain Bird nozzle (sold separately) and screw it onto the riser. Hand-tighten only.
4. Adjust Nozzle Pattern: Use the two-piece ratchet mechanism to align the nozzle pattern as needed. This can be done without tools.
5. Backfill: Carefully backfill the trench, ensuring the sprinkler body remains vertical and at the correct grade. Avoid getting dirt into the sprinkler head during backfilling.
6. Test System: Turn on the water supply to the zone and check for proper pop-up, rotation (if applicable to nozzle type), and coverage. Adjust as necessary.

4. Operation

The Rain Bird 1806 sprinkler body operates by utilizing water pressure to extend the riser and activate the attached nozzle. When the irrigation zone is turned on, water flows into the sprinkler body, causing the internal riser to pop up to its full 6-inch height. The nozzle then distributes water according to its pattern and flow rate. When the water supply is turned off, the pressure-activated seal ensures a positive retraction of the riser, clearing debris and allowing the sprinkler to sit flush with the ground.

The sprinkler body is designed to operate effectively within a maximum pressure of 80 PSI and can handle a maximum flow rate of 15 gallons per minute, depending on the installed nozzle.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your sprinkler system:

• Cleaning: Periodically inspect the sprinkler head for debris accumulation around the riser or nozzle. The precision controlled flush at pop-down helps clear debris, but manual cleaning may be necessary.
• Nozzle Replacement/Adjustment: If the spray pattern is uneven or a different coverage is desired, the nozzle can be easily replaced or adjusted. All components are removable from the top without special tools.
• Wiper Seal Inspection: The co-molded wiper seal is designed for durability, but inspect it annually for any signs of wear or damage that could lead to leaks or improper retraction.
• Winterization: In colder climates, ensure proper winterization procedures are followed to prevent freezing and damage to the sprinkler body and irrigation lines. Consult local guidelines for specific winterization steps.

6. Troubleshooting

If you encounter issues with your Rain Bird 1806 sprinkler body, consider the following:

• Sprinkler Not Popping Up:
  • Check for sufficient water pressure.
  • Inspect for debris obstructing the riser. Remove the top components for cleaning if necessary.
  • Ensure the sprinkler body is not buried too deep.
• Uneven Spray Pattern or Low Flow:
  • Clean or replace the nozzle.
  • Check for clogs in the supply line or filter.
  • Verify adequate water pressure at the sprinkler head.
• Water Leaking from Top of Sprinkler:
  • Inspect the wiper seal for damage or wear. Replace if necessary.
  • Ensure the nozzle and top cap are securely tightened.
• Sprinkler Not Retracting Fully:
  • Clear any dirt or debris around the riser.
  • Check for damage to the riser or spring mechanism.
