What Are the Most Common Causes of Clogged Drains?

Clogged drains are one of the top reasons people call a plumber. Whether it is a toilet, kitchen sink, or washbasin, clogged drains cause extreme discomfort and disruption. They also end up creating flooding, corrosion, and sewage backup. Therefore, it is better to handle them on time before they cause major inconvenience.  

Today, we will discuss the most common causes of clogged drains and how to avoid them. 

Fats, Oils, and Grease Buildup 

People regularly pour a small amount of cooking grease into the drain pipe, which starts accumulating. Initially, it looks harmless, but over time, it starts coating the drain pipe walls and, eventually, combining with other debris, clogs the drain. To avoid this problem, the best way is to collect all the cooking grease in a jar using a spatula and dispose of it in the trash. 

Food Scraps 

People don’t realize and throw food scraps in the kitchen sink, including tea, coffee grounds, egg shells, rice, fruit fiber, etc. Eventually, it badly clogs the drain pipe, causing discomfort. Be careful and throw everything in your household trash, even small food particles. 

Soap Scum 

Most commercially manufactured soaps contain animal fat. When it gets mixed with the minerals in water and soap scum, it is hard to remove from the surface of the bathroom. You can imagine what happens when it goes into drain pipes. It makes a layer in the drain pipe and clogs it over time. Consider buying liquid soap or a bar free from animal fat.

Human hair, when combined with soap scum, debris, and other sticky substances, clog the drain pipe. Install a drain cover and avoid throwing your hair as much as possible. Bath your pets outdoors whenever possible. 

Mineral Buildup 

If your home water is hard, it means it contains a good amount of magnesium, calcium, and other minerals. This can also clog your drain over time. Hydro-jetting is an effective technique for getting rid of it. It removes mineral deposits and unclogs your drain. Consider installing a soft water supply to avoid this issue. 

Flushing Trash 

Unfortunately, many people treat their toilets as trash cans, which causes clogged drains. Do not flush paper towels, diapers, sanitary pads, tissue papers, or other trash. Toilets are meant to flush human waste, not anything else. Keep a trash bin in your bathroom and dispose of trash in it.

They do not dissolve and form stubborn clogs in the sewer lines. You will then need professional drain cleaning services to fix this clogged drain. 

Foreign Objects 

Children most likely throw their small toys and stray items in the toilet and drain. These objects go easily in the drain pipe and get stuck in the pipe’s u-bent. These objects cause serious clogs and inconvenience. The best way to prevent this issue is to keep the toilet seats closed and install drain covers to protect showers, sinks, and bathtub drains.
