You've all seen it, but you've never wondered why this hole exists in your sink.

It is helpful to know

Have you ever wondered why each sink has a small opening - a small hole, respectively, under its faucets?

There are two reasons why this hole is very important.

1. Preventing Water Flowing

The first reason is to prevent the pouring of water from the sink. If you shut down the sink (or the bathtub), or you forget the tap open, the excess of water will go through that hole and go to the canal and thus prevent water from starting to spill onto the floor.

However, if the water from the faucet flows with a large hole, then the pour will occur later, so it is important that you take care not to open the entire faucet, while the pipe is closed.

It should also be noted that it opens its function only when it is left open and the sink is filled with water, but not in situations where the flue is closed, except eventually when it comes to the bathtub, because it is sometimes the greatest distance from the flue and the download tube.

2. Improve the pouring

That opening, in effect, helps the water to get through the flue more quickly in a way that allows air to be found in the flue. Had it not been for the opening, the water would have gushed forth slowly.

Perhaps you have ever noticed that a bubble of soap appears through that opening when a wash comes along, so you put it too far with a bleach, and that's the excess of the air that needs to be released.

Sometimes it must be cleaned

Because it is primarily cared for when people shut down and release water under taps, it does not enter that opening, pollution will be heaped on it, so it is good to clean it over and over again so that the discharge of air and water does not run into obstacles.
