Plumbing Inspection in Mukilteo, WA

21% of owner-occupied homes in Mukilteo have changed hands since 2018. That is an ordinary rate, which makes the ordinary mistake more likely: assuming the inspection covered the plumbing.

The one-paragraph answer

Turnover in Mukilteo sits near the middle, with 21% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

PresalePipe is a referral service, not a contractor or a home inspector. We connect homeowners and buyers with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no inspections and no work, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

When Mukilteo 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 Mukilteo	Share of all owners
Moved in 2021 or later	7%
Moved in 2018–2020	15%
Moved in 2010–2017	25%
Moved in before 2010	54%

Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 8,303 occupied housing units, of which 5,885 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

Visual means visual. Pipe inside a wall, under a slab or below grade is not observed, and neither standard asks anyone to open a sealed access panel to reach it. InterNACHI names polybutylene piping in its exclusions outright.

What it is required to cover

Both standards cover the interior drain, waste and vent system, and ASHI asks for the predominant material of the service, distribution and DWV pipes to be described. A report naming one material is describing the majority of the house, not every run in it.

Worth ten minutes before you read your own report: everything the two standards require, in the order an inspector does it.

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.

Ten minutes of reading covers it: what nobody was required to look at, what they were, and the drain run that is a separate instruction altogether.
