Signs Your Sewer Line Needs Repair

Sewer line problems often develop gradually before becoming major plumbing emergencies. Recognizing the warning signs early can help prevent property damage and more extensive repairs.

You may need sewer line repair if you notice:

  • Multiple drains backing up at the same time
  • Slow-draining sinks, showers, or tubs throughout the property
  • Gurgling sounds from toilets or drains
  • Sewage odors inside or outside the building
  • Water backing up into floor drains
  • Wet or unusually green areas in the yard
  • Frequent drain clogs despite repeated cleaning
  • Foundation moisture near sewer piping
  • Wastewater pooling around outdoor cleanouts

If several plumbing fixtures are affected simultaneously, the problem may involve the main sewer line rather than an individual drain.

Common problems


Common Sewer Line Problems We Repair

Sewer systems can experience a variety of issues over time due to age, ground movement, root growth, and everyday use.

Some of the most common sewer line problems we repair include:

  • Cracked sewer pipes
  • Broken pipe sections
  • Tree root intrusion
  • Pipe joint separation
  • Offset sewer pipes caused by shifting soil
  • Corroded or deteriorated piping
  • Minor sewer line leaks
  • Partial pipe collapses
  • Blockages caused by grease or debris
  • Damaged cleanouts

Trenchless sewer repair


Trenchless Sewer Line Repair (Pipe Lining)

Some sewer line problems can be repaired using trenchless methods that minimize excavation. One commonly used option is pipe lining, which creates a durable new lining inside certain damaged sewer pipes without requiring complete replacement.

Trenchless sewer repair may offer benefits such as:

  • Less disruption to landscaping
  • Reduced excavation
  • Shorter project timelines in many situations
  • Restoration of damaged pipe interiors

However, trenchless repair is not appropriate for every sewer line. Pipes that have collapsed completely or experienced extensive structural failure may require traditional repairs or replacement instead.

Diagnosis & repair


How We Diagnose and Repair Sewer Line Issues

Accurate diagnosis is essential for successful sewer repairs. Rather than relying on assumptions, C.A.B. Backflow follows a structured process to identify the source of the problem.

Initial Inspection


We discuss the symptoms you have noticed and evaluate how your plumbing system has been performing.

Sewer Camera Inspection



A camera inspection allows us to examine the inside of the sewer line in real time. This helps identify cracks, root intrusion, corrosion, collapsed sections, blockages, and other hidden problems.

Repair Planning


Once the issue has been identified, we explain the available repair options, discuss the condition of the sewer line, and provide transparent pricing before work begins.

Professional Repair


Our licensed plumbers complete the recommended repair using quality materials and methods that comply with Illinois plumbing codes. After the repair is complete, we verify that the sewer system is operating properly.

Repair vs. Replacement: How We Decide

Not every damaged sewer line needs to be replaced. In many situations, a properly completed repair can restore reliable performance for years to come.

When evaluating your sewer line, we consider several factors, including:

  • The age of the existing pipe
  • The extent of structural damage
  • The number of damaged sections
  • Whether recurring repairs have already been performed
  • The condition of surrounding pipe sections
  • The long-term value of repairing versus replacing the line

If repair provides a dependable solution, we recommend that approach. If replacement offers greater long-term reliability, we explain the reasons clearly so you can make an informed decision based on the condition of your plumbing system.
