This convenient little feature in your sink basin has probably saved you from having to mop up a runny mess if you’ve ever unintentionally left your bathroom tap running.
Even though it’s frequently overlooked, the additional hole in your porcelain bowl is crucial to the operation of your bathroom and also helps keep flooding at bay.

The holes on the basin’s upper wall serve as a crucial safety feature, despite the fact that many people and some animals use them for different purposes.
Overflow holes, which are essential for improving the efficiency of the plumbing system and preventing water damage in dwellings, have been incorporated into sink designs from the late 1800s and early 1900s.
Overflow holes were established in many sink and bathtub designs during the 20th century. Although many contemporary sinks still have overflow holes, some minimalist designs opt to exclude them for aesthetic reasons.
Nonetheless, this crucial safety element is still included in the majority of kitchen and bathroom sinks, particularly those meant for regular use.
Principal roles
This feature’s engineering contributes to the safety and operation of kitchen and bathroom sinks.
There are two main purposes for the overflow hole:
Controls the sink’s water levels: Extra water is diverted by the holes before it overflows the edge. It diverts the extra water to a different drainage pathway, avoiding the sink stopper, after the water level reaches the overflow aperture.
It’s crucial to remember that overflow isn’t a perfect solution, even though it might postpone spills. Water can still overflow a faucet even when it is running at maximum volume, which could result in spills. This restriction highlights how crucial it is to keep an eye on water levels and avoid leaving faucets running unattended.
Although it’s a clever precaution, it functions best when combined with a more comprehensive strategy for water conservation.
enables more effective water drainage: Overflow holes give air a way to enter the drainpipe, balancing pressure and avoiding suction that might impede water flow. Covering the drain opening with water can produce a vacuum effect, which slows drainage and causes air bubbles to form.
These perforations lessen the possibility of clogs or poor drainage by allowing water to drain more easily.
In essence, overflow holes improve the plumbing system’s overall efficiency by facilitating improved ventilation and more seamless water disposal.
What happens to the water?
The Spruce claims that a typical overflow is connected to a concealed conduit that runs around the sink basin’s underside and is essentially undetectable from above and below.
When the water level rises too high, water can enter the channel through one or two holes along the lip of the overflow. The extra water is subsequently sent by this route to an outlet hole that empties into the main plumbing system. The overflow stays open at all times because it functions separately from the sink stopper, guaranteeing that any water that may otherwise spill over is successfully diverted to the drain.
How an overflow hole can be cleaned
For adequate drainage and to avoid offensive odors, the overflow of the sink must be kept clean. Additionally, it
The following are a few efficient ways to manually clean the overflow:
Employ a Flexible Brush: The overflow channel can be deeply penetrated with a long, flexible brush, such as a bottle brush. To get rid of any buildup, gently insert it and scrape the sides.
Vacuum with Hose Attachment: To remove any debris from the overflow, use a wet/dry vacuum with a hose attachment. This works especially well for bigger muck clumps.
Dip in Baking Soda and Vinegar: Fill the overflow with a vinegar and baking soda mixture. To remove any debris, let it sit for 15 to 30 minutes. Then, rinse it off with hot water.
Use a Pipe Cleaner: A pipe cleaner can work wonders for tiny blockages. To remove debris, gently twist it inside the overflow.
Rinse with Hot Water: To help avoid accumulation, rinse the overflow with hot water on a regular basis. Carefully pour hot water down the passage using a pot or kettle.
Frequent Upkeep: Develop the practice of cleaning the overflow once every few months. This preventative strategy will aid in averting more serious problems later.
