What is the hole above the sink for? Do you know what the hole above the sink is for? Depending on the design, your sink may have one, two, or three holes, and these holes may be next to the faucet, on the edge of the sink, or in the wall. You can ask your plumber when you find a good company which is expert in the field on plumbing in Richmond Hill.

Sink hole usage

  • Prevent water spillage
  • Allow air to escape from the sewer drain pipe

Without a hole in the top of the sink, a pool of water will form against the air in the drain pipe. In fact, this part of the sinks functions in such a way that when the sink is filled with water, they do not allow the water to overflow so that it overflows.

The hole above the sink can help you a lot. For example, it has happened that many of us get busy with other things while washing our hands and do not close the faucet. In this situation, the holes will help us to prevent water from spilling into the bathroom and even the reception.

You may have noticed that your bathtub also has a hole or drain valve, but the kitchen sink does not have this useful part. Many people turn on the hot water to fill the tub and then get busy with other things until this is done. In this situation, it is possible for the bathtub to be completely filled with water and we don’t know about it. The hole on the top of the bathtub is also the reason so that the water does not overflow.

In a sink with two basins, if one of the basins is full, the water will be drained from the other basin, and this will prevent water from spilling out of the sink.

Along with the great advantages of the hole above the sink, its main disadvantage is that because it is rarely used, it collects a lot of bacteria that can make you sick if you touch them.

Sometimes the growth of bacteria is accompanied by a bad smell in the sewage, which warns you that it is time to clean it.
