Plumbing Inspection in Duvall, WA
Roughly 23% of the people who own in Duvall 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
23% of owners in Duvall 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 Duvall moved in
With turnover near the middle, roughly one owner in five or six arrived recently. For everyone else the last time the plumbing was examined by a third party was whenever they bought.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 3,995 occupied housing units, of which 3,588 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 covered list is shorter than the excluded one and it is not thin. Every fixture run, every toilet flushed, the drain-waste-vent system described, the water heater and its venting examined, the shut-offs located. That is a real morning of work and it is worth knowing it happened.
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
Two categories are worth chasing before you exchange: water somewhere it should not be, and anything the report could not see the end of. Both are open-ended, and open-ended is what moves a price.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
