A clogged drain is a plumbing problem that occurs when water is unable to flow freely through a drain due to a blockage. This blockage can be caused by a variety of materials, including hair, food waste, grease, soap residue, and other debris that accumulates in the drain over time. When a drain is clogged, water may drain slowly or not at all, leading to backups and potential water damage. A clogged drain can be a frustrating and messy problem. It can also be expensive to fix if left untreated. Fortunately, many clogs can be prevented by understanding the common causes and taking steps to avoid them.

In this article, we’ll explore the most common causes of drain clogs and how you can avoid them to keep your plumbing system running smoothly.

Causes of clogged drain

Hair: Hair is one of the most common causes of drain clogs, especially in bathroom sinks and showers. As hair accumulates in the drain, it can form a blockage that prevents water from flowing freely.

Grease: Cooking oils and fats can also cause drain clogs, especially in kitchen sinks. Grease can solidify in the drain and create a blockage that prevents water from draining properly.

Food Waste: Food scraps, coffee grounds, and other types of organic waste can cause drain clogs in kitchen sinks. These materials can accumulate in the drain and form a blockage that prevents water from flowing freely.

Soap Scum: Soap residue can build up in bathroom sinks and showers over time, forming a layer of scum that can lead to drain clogs.

How to Avoid Them

Install Drain Screens: Installing drain screens in sinks and showers can help prevent hair, food waste, and other debris from entering the drain. These screens are inexpensive and easy to install, and can be a great way to prevent clogs before they occur.

Dispose of Grease Properly: Never pour cooking oils and fats down the drain. Instead, collect them in a container and dispose of them in the trash. You can also wipe down greasy pans and dishes with a paper towel before washing them to remove excess grease.

Use Garbage Disposals Properly: When using a garbage disposal, be sure to run plenty of water to help flush food waste down the drain. Avoid putting large or fibrous items down the disposal, as these can cause clogs.

Use Soap Wisely: Use soap sparingly in the bathroom, especially in sinks and showers. Consider using a mild, pH-balanced soap that won’t leave behind a lot of residue.

Use Drain Cleaners: While drain cleaners can be effective at clearing clogs, they can also damage pipes and harm the environment. If you do choose to use a drain cleaner, be sure to follow the instructions carefully and use it sparingly. Use drain cleaners that are environmentally friendly and safe for your plumbing system.

Regular Maintenance: Regular maintenance can also help prevent drain clogs. Consider scheduling a professional plumbing inspection every year to ensure that your pipes are in good condition and to catch any potential problems before they become major issues.


By understanding the common causes of drain clogs and how to avoid them, you can prevent this frustrating problem from occurring in your home. Installing drain screens, disposing of grease properly, using garbage disposals correctly, and using soap wisely can all help prevent clogs from forming. If you do experience a clog, consider using a drain cleaner carefully or calling a professional plumber for assistance. With these tips in mind, you can keep your plumbing system running smoothly and avoid costly repairs.
