What the camera does
What can a sewer scope inspection reveal?
A lighted waterproof camera provides a direct view of accessible pipe between the entry point and the distance the camera can travel. It can show pipe material changes, roots, open joints, cracks, scale, corrosion, deformation, debris, low areas holding water, and collapsed sections.
A compatible locator can often mark the camera head from the surface and estimate depth. That information is especially useful when a concern needs a repair estimate or falls near a property line or public right-of-way.
Timing matters
When should a homebuyer order a sewer scope?
The inspection is most useful while the purchase agreement still allows time to review findings, request additional evaluation, or obtain a repair estimate. Waiting until after closing removes those planning options.
A scope deserves particular consideration when drains are slow, the property has a backup history, mature roots are near the route, the sewer material is unknown, or an addition and landscaping make the original line path unclear. These clues do not prove damage; they justify looking.
Know the limitations
What can prevent a complete inspection?
A camera cannot travel through a complete blockage or collapse. Heavy wastewater, grease, scale, roots, or debris can also block the view. The line may need clearing or cleaning before a useful recording can be completed.
The camera shows visible interior conditions; it may not prove a tiny leak, exact remaining service life, soil condition, or the quality of a concealed repair. Findings should be interpreted in context rather than treated as an automatic pass-or-fail result.
- Document how far the camera traveled and why it stopped.
- Record inaccessible branches, missing cleanouts, or blocked sections.
- Use additional testing or focused exposure when the evidence remains incomplete.
Keep useful records
What should be included with the inspection?
Ask for a complete, playable recording—not only screenshots—and a plain-language summary of notable findings. The record should identify the access point, direction of travel, approximate distances, and any located surface points.
For Stevens Point properties, retained footage may also help with later municipal coordination. The City specifically advises residents to make sure lateral televising footage can be viewed later.
- Full video file or reliable shareable link
- Pipe material, accessible length, and inspection direction
- Distance and description of each significant concern
- Surface location and estimated depth when available
- Recommended cleaning, monitoring, repair, or specialist follow-up

Homebuyer Sewer Scope Checklist
Use this checklist before and after a sewer scope so the inspection produces useful evidence—not just a verbal opinion. Print it or keep it open while scheduling and reviewing the results.
Before the inspection
- Schedule the scope while the purchase agreement still allows time for follow-up.
- Confirm which cleanout or access point will be used and whether it is accessible.
- Ask what happens if a blockage, roots, or buildup prevents a complete view.
- Request a complete video recording and a plain-language written summary.
- Confirm whether electronic locating and depth estimates are available for significant defects.
Review with the inspector
- Record the pipe material, diameter, inspection direction, and total distance viewed.
- Document roots, cracks, offsets, open joints, corrosion, standing water, deformation, or collapse.
- Mark the approximate surface location and depth of significant findings when possible.
- Note where the camera stopped and why any portion of the line could not be inspected.
- Ask which findings need cleaning, monitoring, repair, replacement, or additional evaluation.
Before closing
- Save the full video file or a reliable shareable link with the written report.
- Clarify whether a defect appears to be on private property or in the public right-of-way.
- Get a property-specific repair estimate when the findings could affect the purchase decision.
- Verify current City program eligibility directly with Stevens Point Public Utilities when relevant.
- Keep inspection records for future maintenance, municipal coordination, and resale documentation.
