Plumbing Inspection in Black Diamond, WA
Black Diamond is a town that moves. 40% of its owner-occupied homes have changed hands since 2018, which puts the plumbing of a great many of them in front of an inspector inside the last few years.
The one-paragraph answer
In Black Diamond, where 40% of owners bought in 2018 or later, a great many homes have been inspected recently. A standard inspection looks at what can be seen and operated; the drain line under the garden is outside its published scope and needs a camera survey.

When Black Diamond moved in
Where houses move this often, inspections are a familiar part of the process and the risk shifts. It stops being whether one was done and becomes whether anyone understood what it was not required to cover.
| Owner households in Black Diamond | Share of all owners |
|---|---|
| Moved in 2021 or later | 19% |
| Moved in 2018–2020 | 21% |
| Moved in 2010–2017 | 22% |
| Moved in before 2010 | 39% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 2,425 occupied housing units, of which 2,124 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
Wells, pumps, pressure tanks, storage tanks and filters are excluded by both standards. On a property with its own supply, the equipment feeding the whole house sits outside the inspection carried out on it.

What it is required to cover
Knowing what is required is what lets you read the report properly. A finding against something the standard covers is a finding; silence about something it excludes is not reassurance. Most people read the document without that distinction and it is the difference between two very different pieces of paper.
The full covered list, and why the distinction between the two lists is the whole of reading a report properly.
What to do about it
Read the exclusions in your own report before the findings. The findings say what was looked at; the exclusions say what you still do not know, and only one of those two lists gets attention.
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.
