The small hole on the sink, which seems unnecessary actually has a surprising function

Cleaning Tip:

• Use a small brush (like a pipe cleaner or toothbrush) with vinegar or mild detergent.
• Flush it out with warm water occasionally to prevent odors and clogs.

Not All Sinks Have Them

While common in bathroom sinks, not all sinks come with an overflow hole—especially some modern, vessel, or designer basins. If your sink lacks one:

• Be extra cautious about leaving the tap running.
• Consider it when choosing a new sink for homes with young children or elderly residents.

Final Thoughts: Small Hole, Big Job

That tiny sink hole you’ve likely ignored for years? It’s working quietly in the background to prevent water disasters and keep your plumbing system running smoothly. It’s a great example of how thoughtful design—though small and simple—can make a big impact in everyday life.

So next time you’re brushing your teeth or rinsing vegetables, take a moment to appreciate that little overflow hole. It’s always on guard—even if you aren’t.
