Sewer Line Preservation: Causes and Solutions

Discovering a clogged sewer line within the confines of one’s home can quickly escalate from a minor inconvenience to an outright nightmare for homeowners. The repercussions of this plumbing predicament are far from pleasant, encompassing distressing issues such as disruptive backups, lingering foul odors, and, in the worst cases, potential water damage that can wreak havoc on both property and peace of mind. Yet, despite the disruptive nature of such an ordeal, many individuals remain unaware of the underlying causes that lead to a clogged sewer line or how to effectively mitigate the risk of encountering this unsettling situation.

In this article, we will discuss the five reasons you might have a clogged sewer line and what you can do to prevent it.

1. Tree Roots

One of the most common causes of a clogged sewer line is tree roots. Trees are attracted to the water and nutrients found in sewer pipes, and over time, their roots can grow into the pipes and cause blockages. This is especially common in older homes with clay pipes, as the roots can easily penetrate the porous material.

Prevention: To prevent tree roots from growing into your sewer line, avoid planting trees near your sewer line. If you have existing trees, consider inspecting them by a professional to see if their roots are causing any damage. You can also inspect your sewer line regularly to catch any potential problems before they become serious.

2. Flushing Non-Biodegradable Items

Another common cause of a clogged sewer line is flushing non-biodegradable items down the toilet or sink. These items include baby wipes, feminine hygiene products, and paper towels. These items, like toilet paper, don’t break down in the sewer system and can quickly cause blockages.

Prevention: To prevent clogs from flushing non-biodegradable items, only flush toilet paper down the toilet. If you need to dispose of other items, such as baby wipes or feminine hygiene products, throw them in the trash instead.

3. Grease and Oil

Grease and oil poured down the drain can also cause clogs in your sewer line. When these substances cool, they solidify and can create blockages in your pipes. This is especially common in kitchen sinks, where people often pour grease down the drain after cooking.

Prevention: To prevent clogs from grease and oil, avoid pouring them down the drain. Instead, let them cool and solidify, then dispose of them in the trash. You can also use a grease trap to catch any grease or oil that may accidentally go down the drain.

4. Foreign Objects in the Sewer Line

Foreign objects in the sewer line can also cause blockages. This can include anything from toys flushed down the toilet to construction debris left in the sewer line during a renovation.

Prevention: To prevent clogs from foreign objects, be careful about what you flush down the toilet or pour down the drain. If you’re renovating, ensure the sewer line is properly protected to prevent debris from getting into the pipes.

5. Aging Pipes

Finally, aging pipes can also contribute to clogged sewer lines. Over time, pipes can become corroded or damaged, creating blockages.

Prevention: To prevent clogs from aging pipes, have a professional inspect your sewer line regularly. If your pipes are old and corroded, consider having them replaced to prevent future problems.


You can avoid this issue by understanding the common causes of clogs and taking steps to prevent them. Whether it’s avoiding flushing non-biodegradable items down the toilet or having your sewer line inspected regularly, there are many things you can do to keep your sewer line running smoothly.
