The kitchen sink is something that most homeowners rely on every single day. The kitchen sink is vital to any home, from washing dishes to washing produce. Unfortunately, kitchen sinks can become clogged with food, grease, and other debris. Clogged kitchen sinks can be a nuisance, as they can cause water not to drain properly and can cause issues such as bad odors and standing water. To ensure that your kitchen sink remains in tip-top condition, it is important to understand why kitchen sinks to become clogged in the first place. Here’s a look at the top reasons why kitchen sinks become clogged.


One of the most common causes of clogged kitchen sinks is grease. Grease is often found in kitchen wastewater from foods such as bacon, hamburgers, and other dishes made with grease. When grease enters the kitchen sink, it coats the pipes and attaches itself to the sides. In time, the grease accumulates and creates an impenetrable blockage in the pipes, causing the water to drain slowly or stop flowing altogether.


Food is another common reason why kitchen sinks become clogged. Food scraps, such as bits of vegetables and grains, can end up in the kitchen sink and accumulate in the pipes. If left alone, these food scraps can form a thick blockage that prevents water from draining properly.


Another common culprit of clogged kitchen sinks is soap. When too much soap is used, it not only accumulates in the pipes but it can also form a soapy blockage which can impede the flow of water.


Hair, especially long strands of hair, can also be a major culprit. Hair can become tangled up in the pipes and, in time, form a blockage. Moreover, hair can combine with soap and other debris to form an even bigger blockage.

Paper Products

Paper products such as paper towels and facial tissue can also contribute to kitchen sink clogs. Though it may seem innocent, these products contain fibers that can become tangled up in the pipes and cause a blockage.


Toys that find their way down the kitchen sink accidently can also cause clogs. Smaller toys, such as Legos, can easily become lodged in the pipes, while larger toys, such as action figures, can become caught on pipe fixtures and form a blockage.

Grit & Grime

Grit and grime can also build up in the pipes, causing them to form clogs. These materials are often found in wastewater and if left to accumulate, can form a thick blockage that prevents water from draining properly.

Dirt & Debris

Dirt and debris are other materials that can build up in kitchen sink pipes over time. These materials may come from the outdoors, such as dirt and leaves, or from indoors, such as dust and other particles. If left to accumulate, these materials can form a solid blockage that prevents water from flowing through the pipes.

Tree Roots

Tree roots can also cause serious blockages in kitchen sink pipes. Tree roots are attracted to water and can grow toward the pipes and become lodged inside, preventing water from flowing through the pipes.

How to Unclog a Clogged Kitchen Sink

The best way to unclog is by using a kitchen drain unblocker. You simply pour down the unblocker into the drain, wait for a few minutes and then flush with hot water. This should dissolve the blockage and allow the water to flow freely. If the clog is particularly stubborn, you may need to use a plunger or snake to clear it out. You can also use chemical and manual methods to clear out the clog.

It is also essential to take preventive measures to stop your kitchen sink from becoming clogged. This includes regularly cleaning the sink strainer to remove food particles and other debris, avoiding pouring grease down the drain, and avoiding flushing paper products down the sink. These steps can help keep your kitchen sink flowing freely and reduce the risk of clogs.
