What is an overflow hole in a washbasin and what is its function

Let's pay attention to a small detail in the sink or bathtub. Many people ignore this inconspicuous element, believing it to be unimportant. However, it is known that this hidden plumbing fixture performs an important function and can prevent serious problems.

If you were wondering what the small hole in the sink is properly called, it is an "overflow." This element was created for a reason: it is designed to avoid possible flooding.

Why do we need this small hole in the sink and how do we handle it? Most of us forget about one important thing: regular cleaning of the overflow. When you use the sink, dirt, mold, and detergent residue can accumulate in the overflow. If you don't pay attention to this, an unpleasant odor may appear over time.
