We bet that you all know the role of the sink in the rooms of your home, moreover, it is only by calling the plumber that you realize the importance of this ceramic sanitary ware in your kitchen or bathroom. Equipped with a drain pipe, this valuable installation makes our daily life easier as well as the majority of household tasks. So, we use the sink for washing food, doing dishes, washing our hands, and a bunch of other uses that rely on water.

That said, to avoid flooding the house, the manufacturers thought of integrating a super interesting option: adding a second hole in the wall of the sink! It was not for fun that they thought of it, but rather for a major security reason. Thus, we find the first hole called the siphon which is directly linked to the water evacuation channels, then a second called the hole of the overflow drain system or overflow orifice which helps counteract flow problems of water. Curious to know how this magic works in your sink? The answer comes straight away!
