3.2 Initial Flush
After installing a new filter, it is recommended to run water through the filtered output for approximately 5 minutes. This flushes out any carbon fines and ensures optimal filter performance.
4. Maintenance

- Turn off the water supply to the faucet.
- Unscrew the filter housing from the base.
- Remove the old filter cartridge.
- Clean the inside of the filter housing and the base.

5. Troubleshooting
5.1 Leaks
If the system leaks after installation or filter replacement, ensure all connections, especially the diverter valve and the filter housing, are tightened correctly. Check the gasket within the filter housing for proper seating and ensure it is not damaged.
5.2 Slow Flow Rate
A slow flow rate can indicate a clogged filter. If the filter has been in use for 6-8 months or has filtered 8000 gallons, it is likely time for a replacement. Ensure the water supply is fully open and there are no kinks in the connecting hoses.
5.3 Unpleasant Taste or Odor
If the filtered water has an unpleasant taste or odor, the filter may be exhausted and require replacement. Ensure the initial flush was performed correctly after installation.
