What’s Hiding Inside the Sewer Line?
A sewer line can appear to function normally while significant defects remain completely hidden underground.
You Can’t Inspect What You Can’t See
Most of a property’s sewer lateral is buried underground. Toilets may flush, sinks may drain, and there may be no obvious signs of a problem inside the home.
That does not tell us what condition the buried piping is in.
A sewer scope allows a camera to travel through the line so conditions inside the piping can be visually observed.
What We Observed
During this sewer scope inspection, a visible crack was observed in the sewer line approximately 87 feet from the camera access point.
Because the defect was underground, it would not have been visible during the general visual inspection of the property.
Why It Matters
Cracks in sewer piping can worsen over time and may contribute to leakage, root intrusion, soil infiltration, or eventual restriction or failure of the line.
The location of a defect can also matter significantly because access and repair requirements can vary depending on where the damaged section is located.
Why a Sewer Scope Is Different
A general home inspection evaluates readily accessible components and conditions. Buried sewer piping cannot be meaningfully evaluated from the surface.
A sewer scope extends the inspection into an area of the property that would otherwise remain unseen.
That is why a home can have apparently functional plumbing while still having a significant defect farther down the sewer lateral.
What Buyers Should Know
A sewer line does not have to be completely blocked to have a problem.
Camera inspections can reveal cracks, offsets, root intrusion, deterioration, obstructions, and other conditions before they become obvious from inside the home.
For this particular inspection, the important discovery was simple: approximately 87 feet away from where the inspection began, the camera found something nobody standing inside the house could see.
