The short answer
Hilo has a median build year of 1977 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.
Hilo has 17,912 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1977 — 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
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.Hilo sits 1 year older than the HI median of 1978. Of the 30 HI towns we route calls in, its housing is older than 60% of them, and by number of homes it ranks 5th.
What 1977 tells you about the pipe in Hilo
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.
66% of occupied homes in Hilo are owner-occupied, 5 points above the HI figure of 61%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Hilo ZIP codes is $78,537, 19% below the HI median of $96,682.

The first thing to establish in Hilo 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.
