The Hidden Dangers of Sewer Line Damage

May 20, 2025

Most homeowners rarely think about their sewer lines—until something goes wrong. Garner Plumbing Services knows how quickly sewer line damage can occur and how quickly it can escalate. When left untreated, sewer line damage can cause health hazards, expensive repairs, and serious property damage. Knowing the warning signs and acting fast protects your home and wallet.

Common Causes

Several factors can lead to sewer line damage. Tree roots often invade sewer pipes through tiny cracks, causing blockages and leaks. Aging pipes made of clay or cast iron can corrode or collapse over time. Severe clogs from grease, wipes, and foreign objects also lead to major damage. In some cases, ground shifting, heavy traffic above ground, or poor initial installation can weaken pipes and cause them to fail.

Warning Signs You Should Never Ignore

Catching issues early saves thousands in repairs. Watch for these red flags:


  • Slow Drains: When multiple drains empty slowly, the problem likely lies in the main sewer line.
  • Sewage Backups: Frequent backups, especially in the lowest drain, often point to a major blockage.
  • Foul Odors: Persistent sewer smells around your home or yard signal a broken or leaking sewer line.
  • Lush Patches of Grass: Unusual green patches in your yard may indicate a leaking underground sewer pipe.
  • Mold Growth: Sewer leaks inside your home can cause rapid mold growth behind walls and under floors.


Backflow issues also connect to sewer line damage. If wastewater flows backward into your sinks, tubs, or toilets, you need immediate help.

Solutions to Sewer Line Damage

Early intervention can often save the sewer line with professional cleaning. High-pressure hydro jetting clears out stubborn clogs and restores flow. If the damage is extensive, sewer line replacement might be necessary. Modern trenchless technology allows repairs with minimal digging and disruption.


Trust an expert plumber to assess the situation and recommend the best solution based on the condition of your pipes. Acting fast prevents further damage and protects your home’s foundation.
