Most bathroom sinks have a small hole located near the faucet. Many people wonder if this hole is unnecessary or if it has a specific purpose.
That little hole in the sink under the faucet isn’t there for a reason.
It has two very important functions.
The first function is to allow water to drain more easily.
Without this hole, the water would take much longer to drain. Thanks to the hole, the air from above allows the water to flow faster in the sink.
Another no less important function of this hole is the unhindered flow of water in case of blockage.
While it is connected to the main drain pipe, if there is a blockage, the water will start to flow back through this small opening into the sink.
While beneficial, this overflow hole can also cause users some inconvenience. Since it is located in a somewhat awkward spot, it can easily accumulate bacteria and mold, leading to unpleasant odors rising from the pipes.
So, if you notice an unpleasant smell in the bathroom, especially coming from this small hole, you can mix vinegar with baking soda and place the mixture into the hole of the sink.
The chemical reaction will help remove the dirt from the pipes within 5 to 10 minutes. Finally, flush the sink with warm water to complete the cleaning process. This method will ensure your bathroom remains fresh and clean.
