- Drain Maintenance: Regularly clean the basket strainer to remove food debris and ensure efficient drainage.
7. Troubleshooting
This section addresses common issues you might encounter with your kitchen sink.
- Slow Drainage:
- Check if the basket strainer is clogged with food debris. Clean it thoroughly.

- Leaks Around Drain:
- Ensure all drain assembly connections are tight.
- Verify that all rubber gaskets and seals are correctly positioned and not damaged.
