When purchasing a sink, many people may have noticed that there is a small hole at the top.
Some people think that this is just a decorative element, but this detail has a more important purpose.
What is the function of the hole in the sink
The main purpose of the hole at the top of the sink is to prevent water from overflowing. A simple example: the sink can become clogged, causing the water level to rise. When the water reaches this hole, it should start draining into the sewer pipe. This hole has a clear purpose, but even here, everything is not so obvious.
What mistake many people make
The problem is that this hole in most situations remains simply a decorative element.
When installing a sink, many people do not even think about its connection, making a serious mistake. Engineers designed and implemented it for a reason, but many simply ignore its purpose.
Rational component
Plumbers can tell from experience that this hole is not capable of coping with its task 100%.
Of course, if the drain is completely blocked and the water pressure is strong, this hole will not be able to drain all the excess water. As a result, the water will go up. But, it is important to understand that this hole is provided for comfortable use of the sink, and not for extraordinary situations.
