Understanding Sewer Line Camera Inspections
Category: sewer | Difficulty: beginner
Video camera inspections reveal the true condition of your underground sewer pipes without digging. Learn what to expect.
When to Get a Camera Inspection
A sewer camera inspection is recommended in several situations: when you experience recurring sewer line clogs, before purchasing an older home (homes built before 1970 often have clay or Orangeburg pipes nearing end of life), when you notice signs of sewer problems (slow drains, yard odors, sinkholes), or after clearing a major blockage to assess the pipe's overall condition. The inspection is also valuable after sewer line repairs to verify the work was done correctly.
What the Inspection Involves
A professional plumber inserts a waterproof camera attached to a flexible push cable into the sewer line through a cleanout or removed toilet. The camera transmits real-time video to a monitor while a technician advances it through the entire length of the pipe. Modern cameras include a radio transmitter that allows the technician to mark the exact surface location and depth of any problems found. The inspection typically takes 30 to 60 minutes for a standard residential sewer line and costs $150 to $400.
What the Camera Reveals
The camera inspection can identify root intrusion (roots entering through joints or cracks), offset joints (where pipe sections have shifted and no longer align), bellies (low spots where waste and water accumulate), cracks or fractures in the pipe wall, scale and corrosion buildup, pipe material and diameter, and the overall condition of the line from house to municipal connection. The technician should provide you with a video recording and a written report of findings, including the location and severity of any defects.
Using the Results
The camera inspection results guide repair decisions. Minor issues like light root intrusion may be manageable with periodic cleaning and root treatments. Offset joints and bellies may not require immediate action but should be monitored. Major cracks, multiple offsets, or pipe collapse require repair or replacement. For home buyers, the inspection results provide negotiating leverage — the cost of necessary sewer repairs can be requested as a seller concession or reflected in the purchase price. Keep the video recording for future reference and comparison with subsequent inspections.
