Maintenance
Filter Replacement Schedule
For optimal performance and water quality, the CATLINK Ultrafiltration Filter should be replaced every 3 months. Regular replacement ensures continuous effective filtration and helps maintain your pet's health.
Fountain Cleaning
In addition to filter replacement, it is recommended to clean the entire CATLINK PURE 2 fountain regularly (e.g., weekly) to prevent mineral buildup and maintain hygiene. Refer to your CATLINK PURE 2 fountain's instruction manual for detailed cleaning procedures.
Troubleshooting
If you experience issues related to water quality or flow after installing a new filter, consider the following:
- Reduced Water Flow: Ensure the filter is correctly seated and not obstructed. Check if the fountain pump is clean and free of debris.
- Unusual Taste or Odor: If a new filter has an initial slight odor, rinse it thoroughly under running water before installation. If the issue persists, ensure the filter is not expired or damaged.
- Water Clarity Issues: Confirm the filter is installed correctly and that the fountain itself is clean. If the water remains unclear, the filter may be saturated and require replacement, even if before the recommended 3-month period, depending on water hardness and usage.
