How to Tell If Your Sewer Line Is Clogged or Damaged

Jun 18, 2025 | Plumbing Maintenance, Plumbing Repair

Many homeowners in Denton and the Dallas-Fort Worth area may not realize the early warning signs of sewer line damage. Ignoring these signs can lead to more severe plumbing issues, including property damage and costly repairs. Understanding the common indicators can help prevent long-term problems. For those needing immediate help, Christmas Air Conditioning & Plumbing offers sewer line cleaning and repair services to address clogged or broken lines quickly and professionally.

What Causes Sewer Line Damage in North Texas Homes?

Sewer line damage can occur over time or suddenly due to environmental conditions, aging infrastructure, or user habits. Homeowners should be aware of the common causes that affect plumbing systems across North Texas, especially in Denton and the Dallas-Fort Worth metroplex.

Common Environmental and Structural Factors

Shifting soil is a major contributor to sewer pipe damage in Texas. Extended droughts or sudden rain storms can cause the ground to expand or contract, leading to misaligned or broken pipes. Tree roots are also a frequent issue, as they naturally seek moisture and can infiltrate small cracks in sewer lines, growing inside the pipe and blocking the flow. Older homes may also have aging or corroded pipes that weaken over time, making them more likely to collapse or leak.

Plumbing and Human-Related Causes

Improper use of plumbing fixtures contributes to many clogged sewer lines. Pouring grease down the drain, flushing wipes or other non-biodegradable materials, and overloading the system with waste can all lead to blockages. In some cases, poorly installed plumbing or DIY modifications may result in joint failures or the use of low-grade materials that cannot handle normal wastewater flow.

Recognizing these causes can help homeowners take preventive steps and know when it’s time to contact a licensed professional.

Early Warning Signs of Sewer Line Damage

Identifying early signs of sewer line problems can help prevent severe damage and reduce repair costs. Homeowners should monitor their plumbing systems for these common indicators that a sewer line may be clogged or damaged.

Persistent Drain Clogs and Slow Draining Fixtures

One of the most noticeable signs of a sewer line issue is the occurrence of frequent or recurring drain clogs. If multiple drains in the home—including sinks, tubs, and showers—are draining slowly or backing up simultaneously, it may indicate a more significant blockage in the main sewer line. Gurgling noises from toilets or sinks can also indicate trapped air caused by a clog.

Foul Odors Coming from Drains or the Yard

Unpleasant smells emanating from household drains or outdoor areas are another early warning sign. The smell of raw sewage inside the home or a persistent foul odor near the foundation or yard may point to a broken or leaking sewer pipe. These odors are not only unpleasant but can also pose health risks if not addressed promptly.

Unusual Lawn Conditions

Sewer line leaks can affect the ground above the pipe. Homeowners may notice soft, soggy spots on their lawns, even during dry weather. Patches of grass that appear greener or grow faster than the surrounding area may also suggest that sewage is leaking underground and acting as a fertilizer. These lawn changes often go unnoticed until they become more severe.

Advanced Signs Your Sewer Line May Be Severely Clogged or Broken

When sewer line damage progresses beyond the early stages, more serious and costly symptoms may develop. These advanced signs often indicate a severe clog, collapsed pipe, or a major structural issue that requires immediate professional attention.

Sewage Backups or Flooding

One of the most urgent signs of sewer line damage is a sewage backup. If wastewater starts coming up through drains, especially in lower-level fixtures such as basement tubs or floor drains, this indicates a blockage in the main sewer line. In some cases, flooding may occur in the yard or basement, creating a hazardous situation that requires emergency plumbing services.

Foundation Cracks or Sinkholes

When a sewer pipe is broken or leaking underground for an extended period, it can lead to soil erosion beneath the home. This may result in visible foundation cracks, uneven flooring, or even small sinkholes forming on the property. These structural signs may appear unrelated at first, but they often stem from long-term water damage caused by a leaking sewer line.

Severe symptoms like these should not be ignored, as they can lead to significant property damage and high repair costs. Homeowners in Denton and the Dallas-Fort Worth area are encouraged to seek a licensed plumber for sewer line inspection as soon as any of these issues arise.

When to Contact a Professional for Sewer Line Repair

Not all plumbing issues can be resolved with simple drain cleaning or DIY fixes. Knowing when to call a professional is critical to preventing extensive damage and protecting your home’s plumbing system.

Situations That Warrant Immediate Help

Homeowners should contact a licensed plumber immediately if they experience any of the following:

  • Multiple drains clogged at the same time
  • Sewage backing up into toilets, tubs, or floor drains.
  • Persistent foul odors around the home or in the yard
  • Standing water or flooding near cleanouts or outdoor drains

These issues often indicate a deeper sewer line problem that cannot be resolved with household drain cleaners or plunging. Quick action can prevent costly repairs and protect indoor air quality and structural integrity.

Why DIY Sewer Line Fixes Can Be Risky

Attempting to fix a damaged or clogged sewer line without professional tools or training can worsen the problem. Misdiagnosing the issue may lead to unnecessary work or missed signs of deeper pipe failure. In some cases, unlicensed repairs may also violate local plumbing codes or pose safety risks.

Licensed plumbers utilize specialized equipment, such as sewer inspection cameras and hydro-jetting tools, to accurately locate and address the issue. For homeowners in Denton and the Dallas-Fort Worth area, relying on professional services ensures that the job is completed safely and by the code.

The Importance of Sewer Camera Inspections and Professional Diagnosis

Sewer issues below the surface often require more than guesswork. A professional sewer camera inspection is one of the most effective ways to identify the exact location and cause of sewer line damage.

How Sewer Line Inspections Work

Licensed plumbers use waterproof cameras inserted through a cleanout or drain to inspect the interior of the sewer line. The camera transmits real-time video to a monitor, allowing technicians to pinpoint clogs, cracks, root intrusions, or collapsed pipe sections. This method avoids unnecessary digging and helps determine the right solution based on actual footage.

Benefits of a Professional Inspection

A sewer camera inspection offers several key advantages:

  • Accurate diagnosis – Confirms whether the issue is due to a clog, break, or intrusion
  • Faster repairs – Reduces time spent identifying the problem manually
  • Lower costs – Helps avoid trial-and-error repairs or excavation.
  • Informed decisions – Provides visual proof of the issue for insurance or repair estimates.

Homeowners in Denton and the DFW area benefit from these tools by getting fast answers and clear repair recommendations, minimizing both disruption and cost.

Sewer Line Repair and Cleaning Options

Once a sewer line issue is confirmed, licensed professionals will recommend the most suitable repair method. The best solution depends on the location, the extent of the damage, and the type of sewer system in place.

Trenchless Sewer Repair Methods

Modern plumbing technology allows many sewer line issues to be fixed without major digging:

  • Pipe relining involves inserting a flexible liner coated with resin into the damaged section of the pipe. Once the resin hardens, it creates a new pipe inside the old one.
  • Pipe bursting is used when the existing pipe is severely damaged or deteriorated. A bursting head is pulled through the line, breaking apart the old pipe and pulling in a new one at the same time.

Both trenchless options minimize disruption to the yard, driveway, or landscaping and often result in faster project completion.

Traditional Sewer Line Replacement

In some cases, trenchless methods are not possible—such as when the pipe is collapsed or severely offset. Traditional excavation may be required to remove and replace the damaged section. Though more invasive, this method ensures that severely compromised sewer lines are thoroughly removed and restored to working condition.

Professional plumbers will assess the damage using inspection footage and site conditions before recommending either trenchless or traditional repair.
