Amherst Elite Trenchless prepared this field note for Amherst-area property owners. Build a defect map from the access point, distance counter, materials, joints, roots, standing water, transitions, and survey limits.
Begin at station zero
Write down where the camera entered, which direction it traveled, the opening condition, material, diameter, and whether the distance counter was reset. Every later observation depends on that reference.
Field questions to carry into the next step
Keep the property address, access point, pipe material, measured defect stations, unresolved survey limits, and the reason behind each proposed method. Compare complete scopes instead of comparing product labels. Ask who controls permits and inspections, what surfaces are restored, and what closing evidence will be delivered.
Build a simple evidence table with one row for each important station. Include the distance, visible condition, surface location, possible consequence, and the extra observation needed before a decision. Separate confirmed facts from assumptions. A property age can suggest likely materials, but only the exposed or recorded line identifies what is present. Rain timing can suggest infiltration or collection-system involvement, but it does not locate the defect.
Read every proposal beside that table. Check whether cleaning, locating, access, permits, branch connections, downtime, testing, closing footage, and restoration are included. If a bidder rules out a method, ask which recorded condition created that conclusion. If the proposed method changes in the field, require the new finding and revised scope in writing before the work expands.
A decision should remain conditional until the route and condition are documented. If the evidence changes after cleaning or locating, the scope should change with it. Retain the unedited source files, not only screenshots or a short summary. Future owners and service providers need the continuous record to understand what was inspected and what remained unseen.
Separate obstruction from pipe condition
Grease, scale, roots, sediment, and water can hide the wall. Label the first pass accurately and ask whether cleaning is required before a structural recommendation.

Treat transitions as decision points
Connections between cast iron, clay, Orangeburg, and plastic can concentrate movement or root entry. Record the exact station, geometry, and condition on both sides of the transition.

Know what the camera cannot establish
A camera does not directly measure soil support, exterior corrosion, precise slope, or the hidden route beyond a collapse. Surface locating, depth measurement, or other tests may be needed.

Common Questions
What should I keep from a sewer inspection?
Keep the complete video, access location, distance record, material and defect notes, survey limitations, and any written recommendation.
How does this diagnostics field note apply to one property?
Use it as a comparison checklist. The property route, serving system, current camera evidence, and local requirements still need to be confirmed.
Can a website determine the correct repair method?
No. The property and pipe need to be inspected. These field guides help owners compare the evidence and scope they receive.
When should a proposal be revised?
Revise the written scope when cleaning, locating, access, or inspection reveals a condition that changes the selected method, work zone, or restoration.
