Plumbing Inspection in Oswego, IL
Roughly 26% of the people who own in Oswego bought since 2018. A normal rate for a town this size, and normal is where the gaps in a standard inspection do their quiet work.
The one-paragraph answer
26% of owners in Oswego bought in 2018 or later, an ordinary rate. Ordinary is where the usual mistake happens, which is assuming the inspection covered the plumbing: the buried lateral is excluded by both published standards.

When Oswego moved in
A middling turnover figure is the least informative kind, which is its own useful fact: it means you cannot infer much about any particular house from the town, and the report on the one in front of you is the only evidence that counts.
| Owner households in Oswego | Share of all owners |
|---|---|
| Moved in 2021 or later | 7% |
| Moved in 2018–2020 | 18% |
| Moved in 2010–2017 | 26% |
| Moved in before 2010 | 48% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 14,200 occupied housing units, of which 12,240 are owner-occupied. This counts when the CURRENT occupant moved in, so it measures recent moves as a share of the housing stock — not a rate of sales per year.
What the inspection will not cover
Clothes washer connections are excluded, which surprises people because the machine is in the house and plumbed into it. The supply valves behind it and the standpipe it drains into were not part of the job.

What it is required to cover
ASHI requires the energy source and vent system of the water heating equipment to be covered, and InterNACHI requires the same ground from the other direction. Where the two standards overlap is the part of the report you can rely on whichever association the inspector belongs to.
The full list of obligations is published here. Reading it once is what stops a standard note from looking like a finding.
What to do about it
If you are selling, establish it before somebody else does. The same finding is worth more to a buyer who discovered it than to one who was told.
The two standards are published in full and worth ten minutes: what is excluded, what is covered, and why the drains outside the house are a separate instruction.
