What Are The Common Causes Of Drain Blockages? The Top 10 Reasons

A clogged drain is a common household woe, often causing inconvenience and frustration. But what exactly leads to these drain blockages, and how can you prevent them? In this blog post, we’ll explore the most common causes of drain blockages and provide valuable tips to help you keep your drains flowing smoothly.

1. Foreign Objects:

One of the primary culprits of drain blockages is the unintended introduction of foreign objects into our plumbing systems. Small items like toys, dental floss, or non-flushable wipes may find their way into toilets or get washed down sink drains, leading to obstructions. To prevent this, be mindful of what you flush or wash down the drain.

2. Hair Buildup:

In bathrooms, particularly in showers and sinks, hair buildup is a prevalent issue. Over time, strands of hair can accumulate and tangle, creating a barrier that traps soap scum and other debris. Using drain covers and regularly cleaning them can help mitigate this problem.

3. Grease and Cooking Oil:

In the kitchen, grease and cooking oil are common drain blockers. When poured down the sink, these substances may appear harmless at first but can congeal and adhere to the inside of pipes, restricting the flow of water. Dispose of grease properly by letting it cool, solidify, and then throw it in the trash.

4. Food Scraps:

Kitchen sink drains are also susceptible to blockages from food scraps. Materials that don’t easily break down, such as coffee grounds, rice, and pasta, can accumulate over time. Use a sink strainer to catch food scraps and dispose of them in the trash or compost.

5. Toilet Paper and Tissue:

Excessive use of toilet paper or flushing tissues down the toilet can lead to toilet drain blockages. To prevent this, use an appropriate amount of toilet paper and dispose of tissues in the trash when needed.

6. Tree Roots:

In outdoor sewer lines, tree and plant roots can infiltrate, causing blockages and pipe damage. Regular inspections and root barriers can help address this issue.

7. Soap Scum:

Soap scum can build up in bath and shower drains, especially in areas with hard water. Regular cleaning of drains and the use of water softeners can alleviate this problem.

8. Mineral Deposits:

In regions with hard water, mineral deposits like calcium and magnesium can accumulate in pipes, reducing the pipe’s diameter. Consider using a water softener to reduce mineral buildup.

9. Collapsed Pipes:

Deterioration or external factors can lead to the collapse of pipes, causing blockages. Periodic plumbing inspections can help identify and repair damaged pipes.

10. Debris and Dirt:

Outdoor drains, such as gutters and stormwater drains, can become blocked by leaves, sticks, and other debris, especially during heavy rain. Regular cleaning and maintenance of these drains are crucial.

Preventing Drain Blockages

Understanding the common causes of drain blockages is the first step in preventing these pesky issues. By taking proactive measures such as proper disposal of waste, regular maintenance, and the use of drain covers and strainers, you can keep your drains flowing smoothly and avoid the inconvenience and expense of clogged drains. Remember that when blockages do occur, addressing them promptly is essential to prevent more extensive damage to your plumbing system.
