Signs of a Broken Sewer Line
Dealing with a broken sewer line is never fun. But recognizing the warning signs early will help you to avoid costly repairs and save you time. You can catch these problems before they escalate if you know what to look for. Here’s what you need to know.
What Is a Sewer Line and Why Is It Important?
A sewer line is an underground pipe that carries wastewater from your home to the municipal sewer system. These pipes can deteriorate over time, creating cracks, corrosion, and blockages caused by tree roots and debris. A broken sewer line can create sewage leaks, standing water in your home, and contamination in the soil and groundwater.
A broken sewer line isn’t just the problem for your home. It can affect the health of the environment and diminish property value. Thus, sewer line maintenance is critical for you and the surrounding community.
What Causes a Sewer Line to Break?
One common question is why sewer lines fail, and the answer is pretty simple. Sewer lines don’t just break without a reason. Here are some of the usual culprits:
Age and Corrosion
If your house was built prior to the 1980s, it is very likely your sewer line is clay or cast iron. Both clay and cast iron can degrade over time: clay pipes can crack, and cast iron pipes can corrode. Even new PVC pipes can fail.
Tree Roots
Tree roots are sneaky. They will search for any type of moisture they can find. And the root can find moisture through tiny cracks in your sewer line. Once they’re inside your sewer, they continue to grow and expand. The growth clogs pipes, creates leaks and can completely collapse a pipe.
Shifting Soil
Ever notice how your yard settles after heavy rain or construction? That same shifting can put pressure on your sewer line, causing it to crack or misalign.
Blockages
Sometimes, the problem is closer than you think. Flushing “unflushable” things like wipes, grease, or feminine products can create clogs that, over time, damage the pipe itself.
Poor Installation
If your sewer line wasn’t installed properly to begin with, you’re basically sitting on a ticking time bomb. Poor connections and subpar materials often lead to premature failure.
The 4 Major Signs of a Broken Sewer Line
How do you know if you have a broken sewer line? Here are the most common red flags:
- Foul Odors in the House or Yard
Let’s be real—if your house suddenly smells like a public restroom, something’s up. Sewer gas should stay in the pipes, but a crack or clog can let that stink escape.
If the smell is outside, it’s likely your sewer line is leaking into the soil. Inside? That could mean a backup forcing gas up through your drains. Either way, don’t ignore it.
- Slow Drains or Frequent Backups
A slow drain here and there isn’t the end of the world. But if every sink, toilet, and shower in your house starts draining slowly, you might have a main sewer line blockage.
Frequent backups in multiple fixtures are another big clue. Individual clogs tend to stay isolated. When the problem spreads, it’s usually in the main line.
- Unusual Yard Changes
Ever notice a patch of grass that’s oddly green and lush, even during dry weather? That’s not your green thumb—it’s probably sewage leaking underground.
On the flip side, you might notice soggy or sunken areas in your yard. Both are signs that your sewer line has a crack or leak.
- Rodent and Insect Activity
This one is truly the stuff of nightmares. Rats, roaches, and other pests absolutely love broken sewer lines! They can crawl through cracks and make their way into your home through your drains. If you are noticing an increase in pests, especially near your drains, it is definitely time to call a plumber!
How to Confirm a Broken Sewer Line
You may be saying to yourself, “okay, I see the signs, but how do I know for sure?” That’s a great question. Here’s how to confirm the issue:
Start with a Visual Inspection
See if you have any wet areas in your yard or strange smells around the home. Also, note how your drains are functioning. Slow drains or back-ups might mean a blockage has occurred.
Call a Professional for a Camera Inspection
Plumbers have tools like camera systems that can look inside your sewer line. These inspections can spot cracks, clogs, or other damage that isn’t visible otherwise.
Use Pipe Locators
Some plumbers use pipe locators to map out the sewer and find the exact location of the problems so they can avoid digging up parts of the sewer line that aren’t damaged.
Why You Shouldn’t Ignore a Broken Sewer Line
A broken sewer line isn’t just an inconvenience; it can cause serious problems.
Health Risks
When sewage leaks out, it can leak bacteria and viruses. Sewer gas can make you sick too, with headaches, nausea, and breathing issues.
Damage to Your Property
Sewage can leak into your foundation, causing cracks and structural issues. Cleaning up water damage can be expensive and time-consuming.
Environmental Problems
Sewage leaks can hurt soil and water, harming the environment, or local community as well.
Repair Options for a Broken Sewer Line
If you’ve confirmed that you have a broken sewer line, the next step is figuring out how to fix it. There are a couple of options to choose from:
Traditional Excavation
This involves digging up and replacing the damaged pipe. It’s effective but can be costly and disruptive, especially if the pipe is under a driveway or landscaping.
Trenchless Repairs
Trenchless methods are less invasive and include:
- Pipe Relining: A resin-coated liner is inserted into the pipe and hardened, creating a new pipe inside the old one.
- Pipe Bursting: A new pipe is pulled through the old one, breaking it apart as it’s replaced.
These options are faster and require less digging compared to traditional methods.
Preventing Sewer Line Problems
Here’s how you can avoid future sewer line issues:
- Get regular inspections to spot potential problems early.
- Don’t flush anything other than toilet paper and human waste.
- Avoid planting trees near sewer lines to prevent root damage.
- Hire a plumber to clean out grease and debris buildup regularly.
Conclusion
A damaged sewer line may feel overwhelming, but if you notice the signs early enough, you can save yourself money, time, and stress. If you believe there may be an issue, call in professional plumbers, so they can fix the problem quickly. The sooner that you act, the quicker you can protect your home, health, and the environment!
