A standard home inspection is broad and shallow by design. The inspector runs water, checks that drains flow, and moves on. What they do not do — because it requires equipment they do not carry — is look inside the sewer lateral running from the house to the city main.
That pipe is the buyer's responsibility once the deal closes. And on an older Champaign-Urbana property it is frequently the single most expensive undisclosed problem in the transaction.
Why the standard inspection misses it
A sewer lateral can be substantially compromised and still pass a flow test on a Tuesday afternoon with two people in the house. Water goes down. Nothing backs up. Everything looks fine.
Then a family of five moves in, runs the washing machine and two showers on the same morning, and a line that was marginal under light load fails under real load. That is the common story, and the timing — weeks after closing — is not a coincidence.
What the camera actually shows
- Root intrusion, and how far along it is — a few hairlines at one joint is a different situation from a line packed solid.
- Cracks, fractures, and collapse. Including whether the pipe still holds its shape, which determines whether it can be lined or has to be replaced.
- Bellies — sags where the pipe has lost its slope and now holds standing water. These cause chronic recurring backups and cannot be rodded away.
- Offset joints where sections have shifted apart.
- Pipe material. Clay tile, Orangeburg, cast iron, or PVC — this alone tells you a lot about remaining life. Orangeburg in particular is a known-failure material and finding it changes the whole conversation.
- Scale and grease buildup narrowing the effective diameter.
- Improper connections — including the occasional discovery that a previous owner tied a downspout or a sump discharge into the sanitary line, which is usually a code violation.
When it is genuinely non-negotiable
- The house was built before about 1980. Clay tile and cast iron laterals are at or past end of life.
- There are mature trees between the house and the street. See our article on tree roots in sewer lines.
- The property has a finished basement. The consequence of a backup is dramatically more expensive.
- The seller mentions any history of backups or drain work. One rodding disclosed usually means several undisclosed.
- The house sat vacant. Lines that have not been used regularly hide problems well.
For an older house, a camera inspection costs a small fraction of one percent of the purchase price. A full lateral replacement runs into five figures. There are very few inspections with that risk-to-cost ratio.
What you do with the findings
This is where a documented, PACP-coded inspection earns its keep. A national standard condition assessment with video is not one contractor's opinion — it is evidence, and it is far harder to wave off at the negotiating table.
Findings typically lead to one of four outcomes: the seller repairs before closing, the price gets adjusted by the repair estimate, a credit gets issued at closing, or — occasionally, and legitimately — you walk. Any of those beats discovering it in month two.
And when the camera comes back clean, that is worth something too. You know the condition of a component nobody else in the transaction looked at, and you have a baseline for the future.
How to schedule it
Get it done inside your inspection period, at the same time as the general inspection if possible. We can usually camera a lateral within a day or two of the call and get you the video and findings the same day.
Our crews are NASSCO-certified drain professionals with PACP-certified inspectors, and if the line does need work, we can quote both trenchless and conventional options so you know the real range before you negotiate. Get it on the schedule.
