The short answer
The median build year in Riverhead is 1979, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.
Sources: US Census Bureau, American Community Survey 5-year estimates, table B25035; normal and low ranges as published by Grundfos in its homeowner guide to low water pressure.
Riverhead has 11,404 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1979 — 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 1979 tells you about the pipe in Riverhead
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.
70% of occupied homes in Riverhead are owner-occupied, 24 points above the NY figure of 46%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

The first thing to establish in Riverhead 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.
