Sewer Camera Inspection vs. Traditional Sewer Inspection: What’s the Difference?
Problems with a property’s sewer system are not always immediately apparent. Even when plumbing fixtures appear to function normally, underlying issues may still exist. For homeowners and prospective buyers, this uncertainty can raise questions about how thoroughly the sewer system should be evaluated.
Different inspection approaches are available depending on the situation. Understanding how a traditional inspection compares with a sewer camera inspection can help you determine what type of assessment may be needed. This article examines their differences and the considerations involved in choosing between them.
Understanding Traditional Sewer Inspections
A traditional sewer inspection involves checking drainage performance and examining accessible plumbing components. An inspector may run water through sinks and tubs, flush toilets, and observe whether wastewater drains as expected. Visible pipe connections and areas around floor drains may also be checked for leaks, standing water, or signs of previous backups.
The findings are then documented, and any concerns that require further investigation may be referred to a qualified plumbing professional.
How Does a Sewer Camera Inspection Work?
During a sewer camera inspection, an inspector feeds a flexible cable with a waterproof camera through a suitable cleanout or other accessible opening. The camera sends live video as it travels through the sewer line, allowing the inspector to examine visible sections of the pipe.
The images may show tree roots entering through joints, accumulated debris, cracks, displaced connections, or sections that appear damaged. Footage can help locate a visible defect and support recommendations for further evaluation or repair.
Key Differences Between Sewer Camera and Traditional Sewer Inspections
Both methods provide useful information, but they are designed to answer different questions. The table below compares their scope, findings, limitations, and cost.
Comparison factor | Traditional sewer inspection | Sewer camera inspection |
Inspection approach | Observes accessible plumbing and checks drainage performance at fixtures. | Feeds a camera into the sewer pipe to view its interior. |
Visibility | Shows surface conditions and symptoms, not the inside of buried lines. | Shows the interior of pipe sections the camera can reach. |
Problems identified | May reveal slow drainage, visible leaks, odors, or signs of backups. | May reveal roots, obstructions, cracks, offsets, and damaged joints. |
Findings | Relies on observed performance and visible conditions. | Provides visual footage that can help document specific defects. |
Limitations | Cannot establish the condition of hidden pipe interiors. | Limited by access, obstructions, water, and camera visibility. |
Cost | Often part of a broader plumbing or home inspection assessment. | Commonly a separate service with an additional charge. |
Which Sewer Inspection Method Should You Choose?
Choosing between a traditional sewer inspection and a sewer camera inspection depends on several factors. Consider the following before deciding which approach is appropriate for your property.
- Purpose of the Inspection: Determine whether you need a routine plumbing assessment or want to investigate a specific concern involving the sewer line.
- Existing Drainage Problems: Recurring clogs, slow drainage across multiple fixtures, and wastewater backups may indicate the need for a closer examination of the sewer line.
- Property Age and History: Older properties, previous sewer repairs, and mature trees near underground pipes may warrant additional investigation, even when obvious drainage problems are absent.
- Accessibility of the Sewer Line: Consider whether the property has a suitable cleanout or another access point. Access conditions can affect the feasibility and scope of an internal pipe inspection.
These factors can help you select an appropriate inspection method based on your property’s needs.
Conclusion
Traditional inspections can identify visible plumbing concerns and drainage symptoms. Camera inspections provide a closer look at the inside of accessible sewer pipes. Choosing between them depends on whether you need a general assessment or further information about a possible hidden problem.
