The report summarizes the inspector’s observations and recommendations. The video provides visual context and may help a qualified contractor understand the area being discussed. Together, they can help the buyer ask more informed questions.
When reviewing the results, consider:
- Was the intended portion of the line inspected?
- Did the camera reach the municipal connection or another identifiable termination point?
- Was visibility limited by water, debris, buildup, or pipe condition?
- Did the report recommend cleaning, locating, or specialist evaluation?
- Are distances or approximate locations included?
- Does the property have relevant maintenance, repair, or replacement records?

Root intrusion
Roots may enter a sewer line where an opening already exists, such as a crack, loose joint, or damaged connection. Once inside, they can continue growing and may contribute to restricted flow or a backup.
Not every visible root has the same significance. A small amount at one joint is different from dense growth occupying much of the pipe. The surrounding pipe condition, amount of intrusion, apparent effect on drainage, and history of recurring cleaning all deserve consideration.
Depending on what is observed, a recommendation may include cleaning and reinspecting the line, establishing a maintenance plan, or having a qualified sewer contractor evaluate the affected section. Root removal alone may not explain or correct the opening that allowed entry, so the condition of the pipe at that location also matters.
Cracks, breaks, and openings
A camera may reveal a visible crack, broken section, hole, or opening between pipe segments. These findings can vary considerably in size, location, and effect.
An opening may allow water, soil, or roots to enter the line. A more substantial break can affect the pipe’s shape or interfere with the camera’s travel. Camera footage documents the interior view, but it may not show the full exterior extent of the damage.
The report may recommend locating the area from the surface or obtaining a contractor’s evaluation. Location information can be especially useful when the buyer is seeking repair options or estimates.
Separated or offset connections
Sewer piping is commonly assembled in sections. Where two sections meet, the camera may show that the connection is not evenly aligned.
A slight irregularity and a substantial displacement are not equivalent. The size of the offset, whether material appears to collect there, whether roots or soil are entering, and whether the camera can continue all affect the interpretation.
An offset can sometimes create an edge that catches waste or debris. It may also indicate movement or an installation-related concern. Determining the appropriate response may require review by a qualified sewer contractor.
Debris, buildup, or an obstruction
Grease, waste, mineral deposits, foreign material, and other debris can reduce the usable interior space of a sewer line. Sometimes the material merely affects visibility. In other cases, it can restrict the camera or interfere with drainage.
If the camera cannot pass an obstruction, the portion beyond that point was not inspected. That limitation is important even when the visible portion appears acceptable.
Cleaning followed by another camera inspection may be recommended. The second inspection can provide a clearer view and may allow the camera to reach areas that were inaccessible during the original scope.
Our earlier article, Five Sewer Line Problems That May Be Hidden Beneath a Twin Cities Home, provides additional background on these common observations.
Standing water or a low area
Standing water may indicate that a section of the sewer line was not draining completely at the time of inspection. This condition is sometimes described as a low area or “belly.”
The amount of visible water matters. A shallow area that does not prevent inspection is different from a section in which the camera becomes submerged and the pipe cannot be adequately observed. The depth and length of the affected area, the amount of pipe obscured, and any related buildup or drainage symptoms should be considered together.
A sewer camera can document the presence of water, but it does not independently establish the exact slope, depth, or exterior cause of the condition. Additional locating or contractor evaluation may be needed.
Deterioration, corrosion, scaling, or deformation
Different sewer-line materials age and respond to surrounding conditions differently. A report may describe a rough interior surface, corrosion, scaling, deterioration, deformation, or a partial loss of the pipe’s original shape.
These terms describe what was visible; they do not by themselves determine the pipe’s remaining service life. The extent of the change, the material involved, apparent drainage, other defects, and whether the camera could pass through the section all help determine the appropriate next step.

Material transitions and previous repairs
A sewer scope may show a transition from one pipe material to another or evidence of a previous repair. A transition is not automatically a defect. It may simply confirm that part of the line was repaired, replaced, or constructed differently.
The connection between the materials still deserves attention. Buyers should consider whether the transition appears aligned, whether an opening or root entry is visible, and whether documentation exists for the prior work.
Useful records may include invoices, permits, warranties, repair diagrams, prior videos, or information about where the work began and ended. A statement that the sewer was “replaced” should be clarified whenever possible because it may refer to one section rather than the entire private line.
When the inspection is incomplete
Sometimes the most important result is that the entire intended line could not be observed.
The camera may be stopped by debris, roots, standing water, a tight bend, a damaged section, limited access, or another physical condition. Visibility can also be reduced even when the camera continues forward.
An incomplete inspection does not prove that the unseen portion is defective. It means its condition remains unknown. Depending on the reason, the next step may be cleaning, creating or improving access, locating the stopping point, or arranging further evaluation and reinspection.
Does a finding mean the line must be replaced?
No single descriptive term automatically means that the entire sewer line requires replacement.
The appropriate response depends on the complete set of observations and the advice of qualified professionals. Possible next steps may include:
- Requesting maintenance and repair records
- Cleaning the line and completing another scope
- Locating a specific area from the surface
- Asking a qualified sewer contractor to evaluate the finding
- Obtaining repair or replacement options and estimates
- Reviewing warranty coverage when applicable
- Confirming private and municipal responsibility
The buyer, with guidance from appropriate advisers, decides how the information affects the real estate transaction. The inspector’s role is to document visible conditions and recommend further action when warranted.
Questions buyers can ask after receiving the report
A focused conversation can be more useful than reacting to one image or unfamiliar term. Consider asking:
- How much of the intended sewer line was visible?
- Where is the finding located, and is that location approximate?
- Did the condition limit the camera’s travel or visibility?
- Is cleaning recommended before further evaluation?
- Should the line be reinspected after cleaning?
- Is evaluation by a qualified sewer contractor recommended?
- Are prior repair, cleaning, permit, or warranty records available?
- Which portion of the line is the property owner’s responsibility?
For newer and newly constructed properties, Do Newer Twin Cities Homes Need a Sewer Scope? explains why modern materials and recent construction do not provide a complete view of a buried line.
Use the findings to determine the next step
A sewer-scope finding is information, not a verdict on the home.
Some inspections document no significant visible concern in the accessible line. Others identify a maintenance item, an area that should be monitored, a limitation that prevents complete evaluation, or a condition that deserves prompt specialist review.
Understanding the wording, reviewing the video, and following the report’s recommendations can help the buyer move from an unfamiliar observation to a practical next step.
