Amherst Elite Trenchless prepared this field note for Amherst-area property owners. How Amherst sanitary sewer I&I inspections, covered pre-1965 homes, defect records, and correction paths fit a property transfer.
Start with the municipal rule, not a generic home-inspection checklist
The Town of Amherst publishes a Time of Sale sanitary sewer inflow and infiltration inspection process for covered residential structures built before 1965 in the designated area. A buyer, seller, attorney, or agent should verify whether the parcel is covered and which current forms apply. This municipal review and a private due-diligence camera scope may overlap, but they should not be assumed to be identical.
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.
Keep the full lateral record
Ask for the inspection date, access point, distance reached, pipe material, visible defects, and the complete video. If the run could not be completed because of a trap, blockage, missing cleanout, or collapse, keep that limitation visible during negotiation.

Turn a defect into a comparable correction scope
A useful correction proposal identifies the station, material, affected length, method, access, permits, restoration, and closing proof. Root entry at one joint is a different decision from widespread corrosion, a belly, or a full collapse.

Preserve evidence at closing
Store the municipal paperwork, contractor scope, before-and-after video, invoices, product or replacement-pipe details, and inspection signoff with the property file. Those records can prevent the same buried question from reopening during a later transfer.

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 home buying 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.
