Plumbing Inspection in Londonderry, NH
Londonderry turns over at about the national middle: 19% of its owner households arrived in 2018 or later. Common enough that most people know somebody who has had a report, rare enough that few have read the exclusions in one.
The one-paragraph answer
In Londonderry, 19% of owner-occupied homes have changed hands since 2018. Whichever side of a sale you are on, the exclusions decide what you know: a standard inspection stops at the visible plumbing and leaves the sewer lateral to a camera survey.

When Londonderry 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 Londonderry | Share of all owners |
|---|---|
| Moved in 2021 or later | 4% |
| Moved in 2018–2020 | 15% |
| Moved in 2010–2017 | 30% |
| Moved in before 2010 | 51% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 9,482 occupied housing units, of which 8,176 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
Neither standard requires an inspector to determine water flow, pressure, quality or potability. A report can be entirely clean on a house whose water arrives at a pressure nobody would live with, because that was never a defect it was looking for.

What it is required to cover
The water heater is covered in more detail than most of the system: InterNACHI takes in the energy source, the venting connections, the temperature and pressure-relief valve, seismic bracing where it applies, and the labeled capacity. What it stops short of is operating any of it.
The covered list in full. Most people read the exclusions and stop; the two only mean anything against each other.
What to do about it
Write down where the main water shut-off and the main fuel shut-off are. InterNACHI requires both locations to be described, and they are the two most useful lines in the document.
Before you accept a report, read what it did not have to cover against what it did. Then decide whether the drains outside need their own visit.
