​Why Sewer Problems Are Common in Central Texas

Homes across New Braunfels, Seguin, and surrounding communities often deal with sewer line issues due to a few regional factors.
Central Texas soil conditions and aging infrastructure can put stress on underground pipes over time.
Some of the most common causes include:
• Expansive clay soil that shifts during dry and wet cycles
• Tree roots searching for moisture inside sewer pipes
• Older clay or cast iron sewer lines deteriorating
• Grease and debris buildup inside main lines
• Ground movement causing pipe misalignment
These issues are especially common in older neighborhoods across San Marcos, Gonzales, La Vernia, and surrounding areas where original sewer systems may be decades old.


Warning Signs of Sewer Line Damage

Sewer line problems usually start with subtle warning signs before becoming a major backup.
Homeowners should watch for:
  • Multiple drains slowing down at once
  • Toilets bubbling or gurgling
  • Water backing up into tubs or showers
  • Strong sewer odors inside or outside the home
  • Soggy or unusually green patches in the yard
  • Frequent drain clogs throughout the house
If more than one fixture is affected, the problem is often located in the main sewer line rather than a single drain.

Sewer Line Repair vs. Sewer Replacement

Not every sewer problem requires replacing the entire line. A professional inspection can determine the right solution.

Sewer Line Repair
Repairs are often possible when damage is limited to a small section of pipe.
Repairs may address:
  • Minor cracks
  • isolated root intrusion
  • pipe misalignment
  • partial blockages
Targeted repairs can restore function without digging up the entire line.

​Sewer Line Replacement
Replacement may be necessary when the sewer line has widespread damage or has collapsed.
Full replacement is typically recommended when:
  • Pipes have severe corrosion
  • Multiple sections are cracked or broken
  • Tree roots repeatedly invade the line
  • The pipe has collapsed or separated
Modern replacement materials are far more durable and designed to last decades.

The Importance of Sewer Camera Inspections

​How Homeowners Can Prevent Sewer Problems

While some sewer issues happen naturally over time, homeowners can reduce the risk of damage by taking a few preventative steps.
Helpful prevention tips include:
  • Avoid pouring grease or oil down kitchen drains
  • Use drain strainers to catch debris
  • Schedule periodic sewer inspections for older homes
  • Address slow drains before they worsen
  • Be cautious about planting trees near sewer lines
Routine maintenance can often prevent costly sewer emergencies.

Sewer Line Repair and Replacement FAQs

How do I know if my sewer line is broken?
Signs of a broken sewer line often include multiple clogged drains, foul odors, sewage backups, or soggy areas in the yard. A camera inspection is the most reliable way to confirm damage.
Can tree roots really break sewer pipes?
Yes. Tree roots naturally seek moisture and can enter small cracks in sewer lines. Over time they expand inside the pipe and cause major blockages or pipe failure.
How long do sewer lines last?
The lifespan depends on the material. Older clay or cast iron pipes may last 50–75 years, while modern PVC sewer lines can last much longer when properly installed.

Is sewer replacement always expensive?
Not always. The cost depends on the location, length, and condition of the line. Early detection and targeted repairs can often prevent the need for full replacement.
