What Causes the Kitchen Sink to Clog?

 A clogged kitchen sink can put your entire house at a standstill. Without it functioning properly, finding a sanitary place to wash your food, plates, cutlery, and so on is hard. The accumulating filth of food, grease, and oils makes the house look and smell unpleasant. Mixing the bathroom sink with the kitchen sink duties is a no-go due to poor hygiene. So, instead of making your bathroom sink a substitute, let's aim to unclog your kitchen sink. 


But first, let's discuss the multiple possibilities for why your kitchen sink is clogged in the first place. By detecting the source, it will be easier to move on to figuring out how to solve this issue. So, if you're having issues with a clogged kitchen sink, let's work together to determine why this has happened and what you can do about it. Soon enough, you'll return to a normally-functioning kitchen sink!


Here are some reasons why your kitchen sink might clog.


Bits of food


When we wash our dishes, the tiny pieces of food we leave in the plates, or the pans run down the sink drain, accumulating over time. Since these pieces are small, we generally think nothing of them, ignoring the possible repercussions in the coming weeks or months. 


If you are guilty of doing this, as most of us are, ensure you throw away any excess food into the garbage before washing the dishes. 


Grease and oils


Another reason your kitchen sink is clogging up is due to grease buildup. When we wash certain meats in the sink or clean the pans used for cooking, the grease and oils in these products get washed down the sink but not away. 


It stays and hardens over time, creating a blockage that causes your sink to become clogged. Since the viscosity of grease and oil is much more than water, it makes sense that this thickness would cause a buildup. 


Calling a plumber in these tough times may be the best solution. If you have tried fixing the issue yourself but do not see any signs of them working, save time by seeking professional help. They will have your clogged kitchen working as usual in no time! 




Another common culprit in the crime of clogging up a sink is soap. Since we use soap to wash almost everything in the sink, including the sink itself, it's no surprise that this thick and gooey substance would also cause a blockage. Soap can dissolve in water, but when it comes into contact with oil or grease, it can form a thick, sticky substance that accumulates in the pipes over time. 


Additionally, some soaps contain chemicals that can react with the minerals in hard water, creating a layer of scum that clogs pipes. 


Mineral buildup


Mineral buildup is another common cause of kitchen sink clogs. Water with a high mineral content, known as hard water, can cause minerals like calcium and magnesium to accumulate in the pipes and form a hard buildup that restricts water flow. If left untreated, this mineral buildup can become severe and require professional plumbing services.        


Using a plunger in such a situation should get you your desired results within minutes. Simply place the plunger over the drain's opening, ensuring a tight seal to prevent air from escaping. Then begin plunging up and down with firm pressure. You want to create a vacuum to dislodge the clog and help it move down the drain. 


After plunging for a few minutes, remove the plunger and run hot water down the drain to see if the clog has been cleared. If the water isn't flowing, repeat the plunging process a few more times. Once the clog is cleared, run hot water down the drain for a few minutes to flush out any remaining debris.


Ventilation issues


Sometimes, the problem may be ventilation issues with the drains. Without sufficient airflow down the pipes, the water flowing from the tap into the drain will not make its way through as it should. This will cause the water to be blocked. This may occur due to a block in the ventilation system that creates a vacuum, disallowing the proper flow of water. Some signs of problematic ventilation you should look out for are gurgling noises and rising water levels in the sink.


Consider using a plumbing snake for this issue. A plumbing snake is a long, flexible wire with a hook on the end that can be used to remove blockages. To use a plumbing snake, insert the wire into the drain and twist it around to hook onto the blockage. 


Pull the snake out of the drain, and the blockage should come with it. To ensure this has done its duty, run some water and check to see if it runs smoothly down the drain. 


Corroded pipes 


Old and corroded pipes can also contribute to clogs in kitchen sinks. Pipes can deteriorate over time, especially if they are exposed to corrosive materials or if they are not made of durable materials. These damaged pipes can create blockages that constrict water flow in the kitchen sink, thus leading to clogs in the drain.
