While we use the kitchen sink daily, not many pay attention to its small details. Even though the designs of kitchen sinks keep changing to fit modern living spaces, they all have one thing in common: the small circular hole designed next to the sink. This is not a decorative feature but serves a clear functional purpose.
What is the purpose of the circular hole next to the kitchen sink?
The main and most important function of the circular hole next to the kitchen sink is to prevent water overflow. When you forget to turn off the faucet or when the sink is clogged, water will continue to flow and may spill out. This circular hole acts as a backup water outlet, allowing water to escape through an alternative route instead of flooding your entire kitchen.

Water overflowing from the sink can not only make your kitchen floor wet but also potentially damage your kitchen cabinets, electrical appliances, and surrounding furnishings. Water seeping into crevices and soaking into wood or other materials can cause rot, mold, and other types of damage. The circular hole next to the sink helps minimize this risk by allowing water to escape before it overflows onto the kitchen surfaces.
Furthermore, the circular hole also helps maintain stable water pressure in the sink. When water is draining from the sink, this hole allows air to enter the pipe, facilitating faster drainage and preventing water from being held back in the sink due to insufficient pressure.
The circular hole is usually positioned higher than the bottom of the sink but lower than its upper rim. This placement is carefully calculated to ensure that water does not overflow when the sink is almost full, while also being high enough to not interfere with daily dishwashing tasks.
Although the circular hole next to the kitchen sink is a small and simple design feature, it is seamlessly integrated into the overall structure of the sink. The water outlet from this circular hole is typically connected to the main drainage system, allowing water to be naturally and efficiently discharged.
Despite its benefits, this circular hole is located in a hard-to-reach area, making it prone to clogging from dirt, grease, or food debris. When this hole becomes clogged, it loses its ability to prevent water overflow and compromises the efficiency of the drainage system. Therefore, regular inspection and cleaning of this hole are essential to ensure its proper functioning.
If you notice slower water drainage or signs of overflow, the circular hole next to your kitchen sink might be clogged. In this case, immediate cleaning of the hole is necessary to restore its function, prevent water spillage, and maintain stable water pressure during sink usage.
Some tips for using your kitchen sink
Do not pour grease directly into the sink: Grease is a primary culprit of clogs, not only in the circular hole but also in the drainage pipes. Instead of pouring grease down the sink, let it cool and dispose of it in the trash or recycle it if possible.
Regularly clean your sink: In addition to cleaning the circular hole, it is important to periodically clean the entire sink. Use warm water mixed with soap or a cleaning solution to thoroughly clean the sink, especially the areas around the circular hole, to prevent bacterial and mold growth.
Use a drain filter: To minimize the risk of clogs in the circular hole and drainage system, consider using a drain filter to catch food debris and other waste before they have a chance to enter the pipes.
