Clogged Drains: Identifying and Resolving Common Causes

Clogged drains are a very common plumbing issue. The most common causes of clogged drains can be managed fairly easily, but there are times when a clog is so deep that it needs to be addressed by a professional. Before you contact a drainage plumbing service to help unclog your drain, it is important to understand the common causes of clogged drains and what steps you can take to remedy them. 

Common Causes of a Clogged Drain

Many typical household items and practices cause a clog in your drains. Knowing the common causes of a clogged drain can help you identify the issue and determine whether or not you need to contact a drainage plumbing service. The following items and practices can lead to a clogged drain: 

1. Hair 

Hair is a very common cause of a clogged drain. During regular washing or showering, hairs can fall off of your head and body and into the drain. As these hairs accumulate in the drain or pipes, they can form clogs that can be difficult to remove. 

2. Soap

A soap build-up in your drain or pipes can lead to a clog. Soap can leave residue in the drain or pipes, eventually forming a sticky blockage. 

3. Food

Food waste can easily build up in your pipes if you are not careful. It is important to ensure that any food scraps are disposed of in the trash, not your drain. If you do put food down your drain, it can quickly clog up the pipes.

4. Toilet Paper Buildup

Over time, toilet paper can accumulate in pipes, resulting in a clogged toilet or bathtub. This can be a common issue in older homes that have outdated pipes. To prevent this, it is best to flush the toilet after each use and only use enough toilet paper to get the job done.

5. Grease

Grease and oils can also cause clogs in drains and pipes. Grease and oil can harden and form clogs that can be difficult to remove. 

Preventing Drainage Plumbing Issues

Taking certain steps to avoid common plumbing issues, such as clogged drains, is important. The following tips can help you prevent issues with your drains and pipes: 

  • Be careful what you put down your drains. Avoid putting food scraps, grease, and oils down the drain. 
  • Use a drain cover or strainer to keep your drains clear of hair and soap buildup.
  • Regularly pour boiling water down your drain to help clear out debris and buildup.
  • Schedule regular inspections with a professional drainage plumbing service to ensure your drains and pipes are in good condition. 

Contacting a Drainage Plumbing Service

If you have a clogged drain that you cannot fix yourself, it is important to contact a professional drainage plumbing service. A professional can use the right equipment to clear out the clog and identify any issues in the pipes or drains. They can also help you prevent future drainage plumbing issues by performing regular inspections. 


Having clogged drains can be a major inconvenience, but knowing the common causes and how to prevent them can help you avoid these issues in the future. If you are having trouble with a clogged drain, it is important to contact a professional drainage plumbing service to ensure the issue is taken care of correctly.
