The short answer
Kahuku has a median build year of 1978 across its housing. That is late enough for copper and early enough for polybutylene in places, which is why the pattern of the symptom is worth establishing before anybody is called out.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25035.
Kahuku has 803 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1978 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.
What this site is

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.Kahuku sits exactly on the HI median of 1978. Of the 30 HI towns we route calls in, its housing is older than 53% of them, and by number of homes it ranks 27th.
What 1978 tells you about the pipe in Kahuku
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
63% of occupied homes in Kahuku are owner-occupied, which is about the HI figure of 61% once the survey’s margin of error is allowed for. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Kahuku ZIP codes is $73,393, 24% below the HI median of $96,682.

In Kahuku, 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.
