Sink Overflow Holes

sink overflow problemsIf you are meticulous about keeping your bathroom clean, you’ll definitely want to keep reading. Nevertheless, even if you are not, you still may want to understand a little more about your sink’s overflow deterrent. It may prove helpful if you ever forget a faucet is on due to a distraction.
Nearly every sink has an overflow hole that redirects water that would otherwise find its way to your floor. It is a really helpful design that can save you from a mishap.
Well, only if it is working correctly.
Sometimes a lavatory sink’s overflow can become slow draining or in the worst case scenario plugged. If ever it does, the water overflow is hindered and your floor will become a water park in an emergency. Yet, before that occurs a foul smell may be a telling sign that the overflow is becoming compromised.


As time progresses, soap scum, debris, hair, and other items can find its way in the overflow hole. These collection of items can become a breeding ground for disgusting bacteria. When you wash your face, brush your teeth, or simply wash your hands you could be doing so right next to a cesspool of germs.

Fixing The Problem

Cleaning the bacteria in a sink’s overflow hole is usually not on anyone’s to do list (unless you are the meticulous cleaner we mentioned above). Nevertheless, it doesn’t have to be an engaging ordeal. A cup of vinegar funneled down the overflow can do wonders. Vinegar is non-toxic, can kill 99% of bacteria, 82% of mold, and 80% of viruses. Indeed, a little vinegar can help a lot. Additionally, you can use an old toothbrush to clean the edges of the overflow hole.
