The main sewer line is a vital component of any plumbing system. It’s responsible for carrying waste and wastewater from your home or business and directing it to the municipal sewer system. However, over time, the main sewer line can break down, leading to a range of issues. In this article, we’ll explore the most common causes of a broken main sewer line and what you can do to prevent this from happening.

Signs of a Broken Main Sewer Line

Before we delve into the causes of a broken main sewer line, it’s essential to understand the signs that indicate something is wrong. Some of the most common signs of a broken main sewer line include:

1. Slow Drains

If your drains are slow to empty, it could be a sign that there’s a blockage in your main sewer line. The blockage could be caused by anything from tree roots to an accumulation of debris.

2. Foul Odors

If you notice a foul odor emanating from your drains or outside your property, it could be a sign that your main sewer line is broken. The odor is caused by the accumulation of waste and wastewater that’s backing up in your system.

3. Gurgling Sounds

If you hear gurgling sounds coming from your drains, it could be a sign of a broken main sewer line. The gurgling sound is caused by air escaping from your plumbing system due to the blockage.

4. Water Backup

If water is backing up into your sinks, bathtubs, or toilets, it could be a sign of a broken main sewer line. Water backup is a severe issue that requires immediate attention.

Causes of a Broken Main Sewer Line

Now that we’ve covered the signs of a broken main sewer line let’s explore the most common causes of this issue.

1. Tree Roots

Tree roots are one of the most common causes of a broken main sewer line. As trees grow, their roots can penetrate your pipes, causing cracks and blockages. Once the roots enter the pipes, they can continue to grow and cause significant damage.

2. Aging Pipes

Over time, pipes can become worn and corroded, leading to cracks and leaks. Aging pipes are a common cause of a broken main sewer line, especially in older buildings.

3. Ground Shifting

Movement in the ground can cause your pipes to shift and bend, leading to cracks and breaks. Ground shifting can be caused by a range of factors, including earthquakes, landslides, and heavy rainfall.

4. Corrosion

Corrosion is another common cause of a broken main sewer line. Pipes that are exposed to chemicals or other corrosive substances can become weakened over time, leading to cracks and leaks.

5. Human Error

Human error can also cause a broken main sewer line. For example, flushing non-degradable items such as wipes or feminine hygiene products down toilets can cause blockages that lead to a broken main sewer line.

Prevention Tips

Preventing a broken main sewer line is crucial. Here are some tips to help you avoid this issue:

1. Regular Maintenance

Regular maintenance is crucial to preventing a broken main sewer line. Hire a professional plumber to inspect your plumbing system regularly and identify any potential issues.

2. Avoid Planting Trees Near Your Pipes

If you’re planting trees on your property, avoid planting them near your pipes. Tree roots can penetrate your pipes and cause significant damage.

3. Don’t Flush Non-Degradable Items

Avoid flushing non-degradable items such as wipes, sanitary products, and cooking fat down your toilets and drains. These items can cause blockages that lead to a broken main sewer line.

4. Be Mindful of What You Pour Down the Sink

Be mindful of what you pour down your sinks. Avoid pouring substances such as cooking oil or grease down your drains, as these can cause blockages.

What to Do If Your Main Sewer Line Breaks

If your main sewer line breaks, it’s crucial to act quickly. Here’s what you should do:

1. Turn Off Your Water

Turn off your water supply to prevent any further damage.

2. Call a Professional Plumber

Call a professional plumber to assess the situation and make repairs. Attempting to fix a broken main sewer line yourself can lead to further damage and costly repairs.

3. Contact Your Insurance Provider

Contact your insurance provider to see if your policy covers the cost of repairs.

Conclusion

A broken main sewer line is a severe issue that requires immediate attention. While there are several causes of this issue, regular maintenance and taking preventative measures can help you avoid it. If your main sewer line does break, don’t hesitate to call a professional plumber to make repairs. By taking the right steps, you can keep your plumbing system functioning correctly and avoid costly repairs in the future.
