Sewer Scope Inspection
A Sewer Scope Inspection is a visual inspection of the home's main sewer lateral using a specialized high-definition camera inserted into the drain system. The inspection evaluates the condition of the sewer line from the home toward the municipal sewer connection or septic system and can help identify defects that may not be visible during a standard home inspection.
What Is Inspected?
• Main sewer lateral condition
• Pipe material and approximate size
• Root intrusion
• Cracks, fractures, and breaks
• Offset or separated pipe joints
• Bellies (low spots holding water)
• Corrosion and deterioration
• Obstructions and blockages
• Grease buildup and debris accumulation
• Evidence of previous repairs
• Improper pipe slope or installation issues
Common Defects Found
• Tree root intrusion
• Cracked or broken pipes
• Collapsed sewer lines
• Offset joints
• Standing water (bellies)
• Heavy scale buildup in cast iron piping
• Foreign objects obstructing flow
• Separated pipe sections
Benefits of a Sewer Scope Inspection
• Identifies hidden defects before they become costly repairs
• Helps evaluate the remaining service life of the sewer line
• Provides valuable information for home buyers and homeowners
• Can help prevent unexpected sewer backups and property damage
What Is Included
• Video recording of the sewer line inspection
• Images of significant findings when applicable
• Written report documenting observed conditions and recommendations
Limitations
• Inspection is limited to portions of the sewer line accessible by the camera.
• The inspection cannot predict future failures or determine exact remaining life expectancy.
• Some areas may be inaccessible due to blockages, pipe configuration, or other limitations.
A sewer line replacement can cost thousands of dollars. A sewer scope inspection is one of the most valuable additional inspections available when purchasing a home.
