What is the second hole in the sink for?
Have you ever turned on your tap and gone about other things but forgot to turn it off? Several people will raise their hands… If we ignore your water bill which is taking a hit, know that it is the second hole in your sink which saves you from a flood which could reach the neighbors. The disaster, can you imagine? Hats off and many thanks to this small opening to compensate for this pitiful situation!

Indeed, when your sink reaches its full capacity because the drain pipes are blocked or the water flow is too strong to be drained by the main sewer, it is the second hole that comes to the rescue. this blocking with a very intelligent device. Each time a certain water level is exceeded, this outlet hole functions as a good emergency exit: it causes excess water to flow away, preventing any overflow into your basin. Moreover, it is called “overflow” because it occurs when the water is at full capacity. These plumbers are very intelligent, can you confirm?

However, you should not rely on this second hole to drain dirt or vegetable peelings as long as it is not the drainage hole designed for this mission like its friend the siphon. Conclusion: if the water reaches its maximum reservoir, the overflow hole still opens a possible route for it, which is why you should never opt for a basin that is only aesthetic and not at all functional! To the wise…
