The short answer
Housing in Lopez Island runs to a median build year of 1985. Pipe of that era fails in more than one way, so the useful first step is counting weak taps: every tap points at the supply, one tap points at that fixture.

What this site is
PressureTrace is a referral service, not a plumbing contractor. We connect homeowners 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 do not perform plumbing 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.Lopez Island sits 5 years older than the WA median of 1990. Of the 70 WA towns we route calls in, its housing is older than 74% of them, and by number of homes it ranks 64th.
What 1985 tells you about the pipe in Lopez Island
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.
79% of occupied homes in Lopez Island are owner-occupied, 19 points above the WA figure of 60%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Lopez Island, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
