Operation
The DeerValley DV-1U0132 sink functions as a standard bathroom wash basin. The integrated overflow hole is a key operational feature.
Overflow Protection:
The hidden overflow hole is a small opening located at the back of the sink basin. Its purpose is to allow excess water to drain out, preventing the basin from overfilling and potentially causing water damage to the surrounding area. This feature operates automatically when water levels rise above the main drain opening.

Maintenance and Care
Proper care will help maintain the appearance and extend the life of your ceramic sink.
Daily Cleaning:
- Wipe the sink with a damp cloth and mild soap after each use.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
Avoid:
- Abrasive cleaners, scouring pads, or harsh chemicals (e.g., bleach, ammonia-based cleaners) as these can damage the ceramic finish.
- Leaving acidic substances (e.g., lemon juice, vinegar) on the surface for extended periods.

- Leaking Around Drain: Verify that the drain assembly is properly sealed and tightened. Re-apply plumber's putty or silicone sealant if needed.
