Sewer Line Services

Sewer Line Repair & Replacement in Saint Michael, MN

A functioning sewer line is critical for safely transporting wastewater from your home or business to the city’s main system or a septic tank. When sewer lines become damaged or blocked, the result can be slow drains, backups, foul odors, and potential damage to property or landscaping. Ken Betz Plumbing and Drains provides professional sewer line repair and replacement services throughout Saint Michael, MN, helping homeowners and property managers resolve issues quickly and efficiently.

Common Sewer Line Issues

Sewer lines are built to last, but like any underground infrastructure, they’re susceptible to a variety of problems over time. Aging pipes, shifting soil, tree root intrusion, and heavy ground pressure can all cause pipes to deteriorate or collapse.


In many Saint Michael neighborhoods, older homes may still rely on clay or cast iron sewer lines. These materials are especially vulnerable to cracking, corrosion, and joint separation. Even PVC lines, though more durable, can be compromised by poor installation or ground movement.



Clogs caused by grease, debris, or foreign objects also obstruct flow and may mimic the symptoms of structural damage. That’s why proper diagnosis is a critical first step before any repair or replacement work begins.

Sewer Line Repair Methods

After diagnosing the issue—often with a video camera inspection— Ken Betz Plumbing and Drains determines whether the problem can be repaired or if full replacement is necessary. In cases where the damage is limited to a specific section, spot repairs can restore function without replacing the entire line.

Traditional Excavation

For pipes that are severely damaged or inaccessible by trenchless methods, excavation is used to dig out the faulty section, install new piping, and backfill the area. This method provides full access to the pipe and is effective for addressing collapsed lines or root damage.


Trenchless Sewer Repair

In situations where the existing pipe remains largely intact, trenchless methods may be used to avoid full excavation. Pipe bursting and pipe lining (cured-in-place pipe, or CIPP) allow for repairs with minimal surface disruption. These techniques are ideal for preserving lawns, driveways, and landscaping during the repair process.

Each repair is followed by pressure testing and camera inspection to confirm system integrity and flow before closing up the access points.

Identifying Sewer Line Problems

Sewer line issues often begin with subtle signs that worsen over time. Early detection helps prevent full system failure and costly property damage. Common indicators of sewer line problems include:

  • Multiple Slow Drains

    When several fixtures back up or drain slowly at the same time, the issue often lies in the main sewer line rather than in individual drains.

  • Gurgling Sounds or Foul Odors

    Noises from drains and persistent sewage odors indoors or in the yard can point to venting problems or sewer gas escaping from cracked pipes.

  • Wet Patches or Sinkholes

    A leaking or broken sewer line beneath the yard can cause soggy spots, unusually green grass, or depressions in the landscape above the pipe.

  • Sewage Backups

    Sewage coming up from floor drains, bathtubs, or toilets is a clear sign of a serious obstruction or pipe failure that needs immediate attention.

Sewer Line Replacement for Long-Term Solutions

When a sewer line is beyond repair—due to age, extensive root intrusion, or repeated failures—complete replacement is the most reliable solution. Replacement ensures that the entire system meets current code, eliminates chronic issues, and improves flow capacity.


Ken Betz Plumbing and Drains offers full-service sewer line replacement, including permit coordination and final inspections. New pipes are installed using modern materials such as PVC, which resist corrosion, shifting, and intrusion. Proper slope, cleanout access, and venting are factored into the replacement design to ensure reliable long-term performance.
