4. Operating Instructions

The faucet's filter change indicator will reset or can be reset manually after filter replacement, signaling the start of a new filter life cycle.

6. Troubleshooting
This section addresses common issues related to filter replacement. For comprehensive system troubleshooting, please refer to the full Brondell Circle Reverse Osmosis Under Sink Water Filtration System user manual.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water flow is slow after filter replacement. | Air trapped in the system; filters not fully seated; new filters require flushing. | Ensure filters are twisted fully into place. Flush the system by running water for several minutes as per the main manual. |
| Leaking around new filters. | Filters not properly installed or O-rings are misaligned/damaged. | Turn off water supply, remove and re-install filters, ensuring they are twisted securely. Check O-rings for proper seating and damage. |
| Water tastes unusual after replacement. | New carbon filters may release harmless carbon fines; insufficient flushing. | Continue flushing the system for a longer period (e.g., 10-15 minutes) until taste improves. |
