6. Troubleshooting
If you encounter issues with your TOPINCN Round Shower Floor Drain, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow Drainage | Accumulation of hair and debris in the hair catcher or drain pipe. | Remove the lid and hair catcher, clean thoroughly as described in Section 5. If the problem persists, the clog may be further down the plumbing system and require professional assistance. |
| Unpleasant Odors | Buildup of organic matter in the drain or a dry P-trap. | Clean the drain and hair catcher thoroughly. Ensure water is regularly run through the drain to keep the P-trap filled, preventing sewer gases from entering the bathroom. |
| Water Leakage Around Drain | Improper installation or damaged seal. | Ensure the drain base is properly seated and sealed in the shower tray's waste hole. Check for any visible damage to the drain components. Re-installation may be necessary. |
