The short answer
Housing in Waialua runs to a median build year of 1973. 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.

Waialua has 2,291 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1973 — 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 1973 tells you about the pipe in Waialua
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.
62% of occupied homes in Waialua 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 Waialua ZIP codes is $93,875, 3% below the HI median of $96,682.

The first thing to establish in Waialua is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
