Introduction
This manual provides instructions for the Orbit 55035 Nozzle Rack, designed for use with Orbit Saturn III, Saturn IV, and Titan Gear-Drive Rotor Water Sprinklers. The nozzle rack contains a selection of replacement nozzles with varying flow rates (Gallons Per Minute - GPM) to optimize your sprinkler system's performance for different watering needs and soil conditions.
Setup and Nozzle Replacement
The Orbit 55035 Nozzle Rack provides a range of nozzles to customize the water output of your compatible gear-drive rotor sprinklers. Proper nozzle selection is crucial for efficient water distribution and to prevent runoff.
Nozzle Identification

Image 1: The Orbit 55035 Nozzle Rack. This image displays the green plastic rack holding six distinct nozzles, each clearly marked with its Gallons Per Minute (GPM) rating. The nozzles are arranged in two rows, indicating flow rates of 0.5, 1.0, 1.5, 2.0, 3.0, and 5.0 GPM. The 'Orbit' brand logo is visible in the center of the rack.
Replacing a Nozzle
- Turn off Water Supply: Ensure the water supply to the sprinkler system is completely shut off before attempting any nozzle replacement.
- Access Sprinkler Head: Gently pull up the pop-up riser of the sprinkler head to expose the nozzle.
- Remove Old Nozzle: Locate the adjustment screw on the sprinkler head. Using a flathead screwdriver, unscrew the adjustment screw. Carefully pull out the existing nozzle from the sprinkler head.
- Select New Nozzle: Choose the desired GPM nozzle from the Orbit 55035 Nozzle Rack based on your watering requirements (refer to the Operating section for guidance).
- Insert New Nozzle: Align the new nozzle with the opening in the sprinkler head and push it firmly into place. Ensure it is seated correctly.
- Secure Nozzle: Reinsert and tighten the adjustment screw to secure the new nozzle. Do not overtighten.
- Restore Water Supply: Turn the water supply back on and test the sprinkler's operation. Adjust the arc and radius as needed for optimal coverage.
Operating Considerations
The selection of the correct nozzle from the 55035 Nozzle Rack directly impacts the performance of your Saturn III/IV or Titan gear-drive rotor sprinkler. Different GPM nozzles allow for customization of precipitation rate and throw distance.
- Precipitation Rate: Nozzles with lower GPM ratings deliver water at a slower rate, which is ideal for clay soils or sloped areas to prevent runoff and puddling. Higher GPM nozzles are suitable for sandy soils that absorb water quickly.
- Coverage and Distance: While the sprinkler head itself allows for arc and radius adjustment, the nozzle choice influences the overall throw distance and water pattern. Experiment with different nozzles to achieve the desired coverage for your specific landscape.
- System Balance: When replacing nozzles, consider the GPM of other sprinklers in the same zone to maintain a balanced precipitation rate across the entire area. This helps ensure uniform watering.
Maintenance
Regular maintenance of your sprinkler nozzles ensures optimal performance and longevity of your irrigation system.
- Check for Clogging: Periodically inspect nozzles for debris, dirt, or mineral buildup that can obstruct water flow and distort the spray pattern. The bottom inlet filter of the sprinkler head helps prevent clogging, but nozzles can still accumulate particles.
- Cleaning Nozzles: If a nozzle is clogged, remove it as described in the Setup section and gently clean it with a small brush or by rinsing under water. Avoid using sharp objects that could damage the nozzle orifice.
- Inspect for Damage: Check nozzles for any cracks or wear. Damaged nozzles should be replaced to maintain efficient watering.
- Durability: The nozzles and the sprinkler components are made with high-impact ABS and stainless steel for durability. Proper care will extend their lifespan.
Troubleshooting
If your sprinkler system is not performing as expected after nozzle replacement, consider the following:
- Uneven Water Distribution:
- Verify that the correct GPM nozzle has been selected for the specific area and soil type.
- Ensure the nozzle is fully seated and the adjustment screw is tightened appropriately.
- Check for any obstructions in the nozzle or around the sprinkler head.
- Confirm that the sprinkler's arc and radius settings are correctly adjusted.
- Low Water Pressure/Flow:
- Inspect the nozzle for any clogs or debris.
- Check the bottom inlet filter of the sprinkler head for blockages.
- Ensure the main water supply valve is fully open.
- Nozzle Not Fitting Correctly:
- Confirm that you are using the correct nozzle rack (Orbit 55035) for Saturn III/IV & Titan gear-drive rotor sprinklers.
- Ensure the nozzle is oriented correctly before attempting to insert it.
