Sewer lines, like other home systems, eventually require replacement. Ignoring sewer line issues can lead to severe damage and health risks. Exposure to sewer gas can cause nausea, headaches, dizziness, and other health concerns, not to mention unpleasant odors. Addressing sewer line problems promptly is essential.
At M & B Services, we provide expert plumbing solutions in Minneapolis and St. Paul, offering a variety of sewer line repair methods tailored to your property’s needs.
Sewer Line Repair Methods
1. External Excavation
The traditional approach involves digging trenches to expose the sewer line fully. While it makes repairs easier, this method can disrupt landscaping, driveways, or other structures.
2. Interior Access Excavation (Trenchless Repair)
This method minimizes digging, reducing property disruption. Although trenchless repair can be more costly upfront, it often saves money on restoring your yard. Methods like pipe bursting and pipe lining (cured-in-place piping) fall under this category.
Reasons for Excavating Sewer Lines
- Existing Damage: Tree roots, grease buildup, or improper items flushed down the toilet can damage sewer lines. Regular drain cleaning helps prevent costly repairs.
- Septic System Upgrades: Switching from a septic system to a city sewer or repairing an old septic tank may require new sewer line installation.
- New Construction: Installing sewer lines for new residential or commercial properties necessitates excavation.
Sewer Line Excavation Process
Before excavation, all utility lines are marked to prevent service interruptions or injury. Video inspection technology is used to assess the pipes and determine the best repair method. Permits and additional inspections may also be required.
Comparing Repair Methods: Pipe Bursting vs. Open-Top Excavation
Pipe Bursting
Pipe bursting is a trenchless method that removes old pipes and replaces them with new ones using a pneumatic or hydraulic head. This method avoids digging large trenches, minimizes property disruption, and is ideal for homeowners concerned about landscaping damage.
Pipe lining is another trenchless option, relining existing pipes with epoxy to restore their function without removing old pipes. Both techniques can reduce labor costs and the expense of yard restoration.
Open-Top Excavation
When trenchless repairs aren’t feasible, open-top excavation exposes the pipe fully, allowing for comprehensive repairs or replacement. While effective, this method is labor-intensive, time-consuming, and may require extensive restoration of landscaping and structures.
Conclusion
Prompt sewer line replacement is essential to avoid property damage and health risks. Choosing the right repair method—whether trenchless or open-top excavation—depends on the condition of your pipes and property.
