2. Package Contents
Verify that all components are present in the package:
- Neoperl Cache Faucet Aerator (Blue 1.0 gpm, Tiny Junior M18.5)
- Installation/Removal Key
- O-Ring (pre-installed on aerator)
3. Installation
The Neoperl Cache Aerator is designed for easy installation directly into the faucet spout without the need for an external housing. It replaces existing cache aerators.
- Turn off Water Supply: It is recommended to turn off the water supply to the faucet before beginning installation to prevent accidental water flow.
- Remove Existing Aerator: If an existing cache aerator is present, insert the provided installation key into the aerator slots and turn counter-clockwise to unscrew and remove it. Clean any debris from the faucet spout.
- Insert New Aerator: Place the new Neoperl Cache Aerator into the faucet spout opening. Ensure the blue O-ring is properly seated.
- Tighten Aerator: Use the installation key to gently turn the aerator clockwise until it is snug. Do not overtighten.
- Restore Water Supply: Turn the water supply back on and check for leaks. If leaks occur, ensure the aerator is properly seated and tightened.

4. Operation
Once installed, the Neoperl Faucet Aerator operates automatically with the flow of water. It is designed to provide a consistent 1.0 gallons per minute (gpm) flow rate, regardless of water pressure fluctuations between 20 and 80 psi.
- Aerated Stream: The aerator introduces air into the water stream, creating a soft, white, and splash-free flow.
- Water Conservation: The 1.0 gpm flow rate helps conserve water without compromising performance, contributing to lower water consumption.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your aerator.
- Cleaning: If the water flow becomes irregular or reduced, the aerator may need cleaning. Use the installation key to remove the aerator. Rinse it under running water to remove any loose sediment. For stubborn mineral deposits, soak the aerator in a solution of equal parts white vinegar and water for 30 minutes, then scrub gently with a soft brush.
- Anti-Clogging Design: The integrated anti-liming honeycomb screen and anti-clogging dome screen are designed to filter sediment and resist lime build-up, reducing the frequency of cleaning.
- Replacement: If the aerator is damaged or performance significantly degrades after cleaning, it may need to be replaced. Use the model number 16002xx or compatibility with Kohler Service Kit 1278467 when purchasing a replacement.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced or irregular water flow | Sediment or mineral build-up in aerator | Remove and clean the aerator (refer to Section 5). |
| Water leaks from faucet spout | Aerator not seated correctly or O-ring damaged | Remove aerator, check O-ring for damage, re-insert and tighten securely. Replace O-ring or aerator if damaged. |
