The underground pipes that make up your sewer system are out of sight and often out of mind, but they are crucial for the smooth functioning of your home. A broken sewer pipe can lead to a multitude of plumbing problems, ranging from drain issues to severe sewage backups. Identifying the signs of a broken sewer pipe early can save you from costly repairs and replacements down the line.

Radiant® Plumbing and Air Conditioning, serving Austin, San Antonio, and Central Texas since 1999, is here to help you understand and address these issues with our expert, 24/7 service.

Early Warning Signs of a Broken Sewer Pipe

Broken sewer pipes can manifest in numerous ways, often with subtle signs that homeowners might overlook. Here are the common symptoms to watch out for:

Strange Noises from Your Drains

Unusual sounds coming from your drains can be an early indicator of underground pipes in distress. Gurgling noises, particularly after using the toilet or when water drains out, suggest that air is trapped in the sewer line due to a blockage or crack. At Radiant, our experienced plumbers use advanced diagnostic tools to pinpoint and resolve these issues swiftly.

Unpleasant Odors

A properly functioning sewer system should be airtight, except for vent stacks allowing gases to escape. If you detect the foul odor of sewage in or around your home, it could be a sign of a crack or break in the sewer pipe, allowing gases to escape. Trust Radiant to identify and fix these problems, ensuring your home remains safe and comfortable.

Slow Draining

While a single slow drain might just be a clogged pipe, multiple slow drains throughout your home can indicate a more serious problem with the main sewer line. If you’ve tried all the usual fixes for a slow drain with no success, it’s time to consider the possibility of a broken sewer pipe. Radiant’s comprehensive repair services can restore your plumbing system to optimal performance.

Water Damage or Foundation Problems

A broken sewer pipe beneath your home can cause water to leak and erode the soil around your foundation. If you notice new cracks in your foundation, unexplained water damage, or a sudden shift in the soil around your home, a broken sewer line could be the culprit. Radiant’s team is equipped to handle these complex repairs efficiently.

Mold and Mildew

Mold and mildew growth can result from the extra humidity caused by a leaking sewer pipe. If you notice mold or mildew in your home, especially if it’s coupled with a musty odor, it may be time to inspect your sewer lines. Count on Radiant to provide thorough inspections and effective solutions.

Lush Patches of Grass

While lush, green grass can be the result of diligent gardening, it can also signify a sewage leak underground. Sewage acts as a fertilizer, so if you notice that patches of your lawn are particularly vibrant or growing faster than other areas, it could be due to a sewage leak from a broken pipe. Our skilled technicians at Radiant can accurately diagnose and address these leaks.

Pests Invasion

Rodents and insects are attracted to sewage. If you notice an increase in pests like rats or cockroaches around your property, they could be finding their way in through cracks in your sewer pipes. Radiant offers reliable solutions to eliminate these issues and secure your home.

Pools of Septic Waste

One of the most obvious signs of a broken sewer pipe is the pooling of septic waste in your yard. If you see water pooling, and it hasn’t rained recently, you should be concerned about a potential sewer line break. With Radiant’s prompt and professional service, you can resolve these emergencies quickly.

Understanding the Causes of Sewer Pipe Damage

To understand the root of the problem, let’s look at what causes sewer pipes to break:

Tree Roots

Tree roots are attracted to the moisture and nutrients in sewer lines and can grow into the pipes through tiny cracks or loose joints, causing blockages or breaks. Radiant uses state-of-the-art equipment to remove roots and repair the damage.


Older pipes made of cast iron or clay are susceptible to corrosion over time. As the pipes corrode, they can crack or collapse. Radiant’s experienced team can assess the condition of your pipes and recommend the best course of action.

Ground Movement

Shifting soil or heavy construction equipment can cause the ground to move, which in turn can break or dislodge sewer pipes. Radiant’s experts can handle repairs resulting from ground movement, ensuring long-term stability.

Extreme Temperature Changes

Freezing and thawing cycles can cause the ground to expand and contract, which can crack pipes, particularly those that aren’t buried deep enough. Trust Radiant to protect your plumbing system against weather-related damages.

Diagnosing a Broken Sewer Pipe

To diagnose a broken sewer pipe, a professional plumber may perform a camera inspection. This involves sending a camera down your sewer line to visually inspect for damage. The plumber can then determine the location and extent of the damage. Radiant offers cutting-edge diagnostic services to ensure accurate and efficient identification of issues.

Repairing a Broken Sewer Pipe: Your Options Explained

Once a broken sewer pipe is confirmed, there are several methods of repair:

Traditional Repair: Tried and True

This method involves digging up the yard or driveway to access the broken pipe and replacing it. It is invasive and can be costly due to the additional labor and restoration work required. Radiant provides transparent pricing and financing options to help manage costs.

Trenchless Repair: The Modern Solution

Trenchless repair methods, such as pipe lining or pipe bursting, allow for repairs with minimal digging. These methods are less disruptive and can be more cost-effective in the long run. Radiant specializes in these modern techniques, offering efficient and less invasive solutions.

Pipe Replacement: Out with the Old, In with the New

In some cases, particularly with older systems, it may be more practical to replace the entire sewer line rather than repair a single break. Radiant’s experienced team can guide you through the replacement process, ensuring a durable and reliable outcome.

Preventative Measures to Protect Your Plumbing

To prevent future sewer line issues, consider the following:

  • Regular inspections and maintenance
  • Avoid planting trees near sewer lines
  • Proper disposal of grease and waste
  • Using water softeners to minimize pipe corrosion

The Radiant Care Club offers homeowners peace of mind with regular maintenance and priority service, ensuring your plumbing and HVAC systems run smoothly year-round.

Trust Radiant for Your Sewer Pipe Needs
