Sewer Line Inspection: What a Camera Reveals About Your Pipes
Sewer Line Inspection: What a Camera Reveals About Your Pipes
Your sewer line is the most important pipe you never see. Running underground from your home to the municipal sewer (or septic tank), this 4-inch pipe carries all of your home’s wastewater. When it fails, the consequences are severe — sewage backups, yard excavation, and repair costs of $3,000-15,000. A sewer camera inspection ($200-400) lets you see the condition of your sewer line before problems become emergencies.
According to the U.S. Department of Energy (energy.gov) and plumbing industry data, proactive sewer inspections are one of the highest-value plumbing services available, saving homeowners thousands in emergency repairs.
What a Sewer Camera Shows
A professional sewer camera is a waterproof, self-illuminating camera head on a flexible cable that travels through your sewer line, transmitting real-time video to a monitor. The technician can see tree root intrusion (the number one cause of sewer line failure in the DMV), pipe cracks, breaks, and collapses, bellied pipe (sagging sections that collect waste), pipe corrosion and deterioration, offsets at joints where sections have shifted, blockages and buildup, and the pipe material and condition.
When to Schedule a Sewer Inspection
Before buying a home: A sewer camera inspection during the home inspection period can reveal problems that cost $5,000-15,000 to fix. This is the single most valuable pre-purchase plumbing inspection available.
When experiencing recurring clogs or slow drains throughout the house.
When you notice wet spots, sinkholes, or unusually green patches in your yard.
When your home is over 30 years old and the sewer line has never been inspected.
After a sewer backup to determine the cause and condition.
Common Findings and Repair Options
| Finding | Severity | Repair Method | Cost Range |

| Bellied/sagging pipe | Moderate-High | Spot repair or replacement | $2,000-6,000 |
| Cracked or broken pipe | High | Pipe lining (trenchless) or excavation | $3,000-12,000 |
| Offset joints | Moderate-High | Pipe lining or spot repair | $1,500-5,000 |

Trenchless vs. Traditional Repair
Trenchless sewer repair (pipe lining or pipe bursting) repairs or replaces your sewer line without excavating your yard. A resin-coated liner is inserted into the existing pipe and cured in place, creating a new pipe inside the old one. Cost: $4,000-10,000 depending on length and condition. Traditional excavation involves digging a trench to access and replace the pipe. Cost: $5,000-15,000 including landscape restoration.
