Setup and Installation

This insert is intended as a replacement part for compatible Kohler faucets. Installation typically involves removing the existing aerator or insert and replacing it with the new 1104957 part. A specialized aerator wrench may be required for removal and installation, depending on your faucet model.

1. Turn off Water Supply: Locate the water supply valves under your sink and turn them off to prevent accidental water flow during installation.
2. Remove Existing Aerator/Insert: Carefully unscrew the existing aerator or insert from the faucet spout. This may require an aerator wrench or pliers with a cloth to prevent scratching.
3. Clean Faucet Spout: Clean any debris or mineral buildup from the inside of the faucet spout threads.
4. Insert New Laminar Flow Insert: Place the KOHLER 1104957 Laminar Flow Insert into the faucet spout. Ensure it is seated correctly.
5. Secure the Insert: Screw the insert or its housing back into the faucet spout. Hand-tighten first, then use an aerator wrench or pliers (with caution) to snug it securely. Do not overtighten.
6. Restore Water Supply: Slowly turn the water supply valves back on.
7. Check for Leaks: Turn on the faucet and check for any leaks around the newly installed insert. If leaks occur, gently tighten the insert further.

Operating Instructions

Once installed, the laminar flow insert will provide a smooth, clear, and non-splashing stream of water. This design minimizes aeration, resulting in a solid column of water that feels more substantial and reduces splashing in the sink. The 1.5 GPM flow rate is designed for water efficiency while maintaining effective water delivery for daily tasks.

Maintenance

To ensure optimal performance and prevent mineral buildup, periodic cleaning of the laminar flow insert is recommended. If you notice a reduction in water flow or an irregular stream, follow these steps:

1. Remove the Insert: Turn off the water supply and carefully remove the insert as described in the installation steps.
2. Clean Debris: Rinse the insert under running water to remove any loose debris. Use a soft brush (like an old toothbrush) to gently scrub away any mineral deposits or particles from the screens and openings.
3. Soak in Vinegar (if needed): For stubborn mineral buildup, soak the insert in a solution of equal parts white vinegar and water for 30 minutes to an hour. Rinse thoroughly after soaking.
4. Reinstall: Reinstall the clean insert by following the installation steps.

Troubleshooting

• Reduced Water Flow: If water flow is significantly reduced, the insert may be clogged with sediment or mineral deposits. Refer to the Maintenance section for cleaning instructions.
• Splashing or Irregular Stream: This could indicate that the insert is not seated correctly or is partially clogged. Recheck the installation and clean the insert if necessary.
• Leaks Around the Spout: Ensure the insert is properly tightened and that any associated gaskets or O-rings are correctly positioned and not damaged.
