Signs You May Have a Sewer Line Leak
If you notice any of these symptoms, you may have a sewer or drain line issue:
✔ Frequent drain backups
✔ Slow drains in multiple fixtures
✔ Gurgling sounds in toilets or sinks
✔ Sewage odors inside or outside the home
✔ Wet spots or soft soil near the foundation
✔ Cracks in slab or flooring
✔ Insect or rodent activity near drains
✔ Unexplained foundation movement
✔ High water bills (if tied to water lines)
Some of these warning signs can also indicate a hidden slab leak beneath the foundation, which requires specialized detection and repair. Early detection prevents structural damage and expensive repairs.
Common Causes of Sewer & Drain Line Leaks in Dallas Homes
Sewer and drain lines can deteriorate or break due to:
✔ Shifting clay soil (very common in North Texas)
✔ Old cast iron or clay pipes
✔ Pipe corrosion
✔ Tree root intrusion
✔ Poor installation
✔ Ground movement from weather changes
✔ Pipe separation at joints
✔ Heavy vehicle weight near plumbing
✔ Erosion beneath the slab
Dallas homes built before 1990 are especially prone to sewer line issues.
Sewer Camera Inspection — Find the Problem Fast
Before repairing a sewer or drain leak, we perform a sewer camera inspection to locate:
- Cracks
- Breaks
- Root intrusions
- Collapsed sections
- Off-grade pipes
- Belly/dips in the system
- Misaligned joints
This ensures repairs are accurate and cost-effective.
