What Causes Clogged Drains?

Understanding common causes of drain blockages and how to prevent them

Published: January 15, 2024 | Drain Cleaning Tips

Dealing with a clogged drain is one of the most frustrating plumbing problems homeowners face. Understanding what causes these blockages can help you prevent them and know when to call for professional drain cleaning services.

Most Common Causes of Clogged Drains

1. Hair Buildup

Hair is one of the leading causes of bathroom drain clogs. When hair goes down the drain, it tangles with soap scum and other debris, creating stubborn blockages. This is especially common in shower drains and bathroom sinks. Using a drain strainer can significantly reduce hair-related clogs.

2. Grease and Oil

Kitchen drains frequently become clogged due to grease, oil, and fat accumulation. While these substances may be liquid when poured down the drain, they solidify as they cool, coating pipe walls and trapping food particles. Never pour cooking oil down your drains. Instead, collect it in a container and dispose of it properly.

3. Food Waste

Even with a garbage disposal, certain food items should never go down your drain. Coffee grounds, eggshells, pasta, rice, and fibrous vegetables can all contribute to clogs. These items don't break down easily and can accumulate in your pipes over time.

4. Soap Scum

Soap residue combines with minerals in water to form a hard coating inside pipes. This buildup gradually narrows the pipe opening, restricting water flow and eventually causing complete blockages. This problem is particularly prevalent in areas with hard water.

5. Tree Roots

Tree roots naturally seek water sources, and sewer lines are attractive targets. Roots can infiltrate pipes through small cracks or joints, growing inside and blocking water flow. If you have large trees near your sewer line, this could be causing recurring clogs that require professional hydro jetting to resolve.

6. Mineral Deposits

In areas with hard water, minerals like calcium and magnesium can accumulate inside pipes. Over time, these deposits significantly reduce water flow and contribute to blockages. Water softeners can help prevent mineral buildup in your plumbing system.

7. Foreign Objects

Small items accidentally dropped down drains can cause immediate or gradual blockages. Children's toys, hygiene products, and even dental floss can create serious clogs. Only water, toilet paper, and human waste should go down drains.

Warning Signs of a Clogged Drain

  • Slow draining water in sinks, tubs, or showers
  • Gurgling sounds coming from drains
  • Water backing up in unexpected places
  • Unpleasant odors coming from drains
  • Multiple clogged fixtures at once

When to Call a Professional

While minor clogs can sometimes be cleared with a plunger or drain snake, persistent or recurring blockages often indicate a deeper problem. Professional drain cleaning can address the root cause and prevent future issues.

If you're experiencing frequent clogs, slow drains, or suspect tree root intrusion, contact a drain cleaning professional. They have specialized equipment like video cameras for inspection and high-pressure hydro jetting systems that can thoroughly clean your pipes.
