The short answer
Lake Grove has a median build year of 1970 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.

Lake Grove has 4,052 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1970 — 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 1970 tells you about the pipe in Lake Grove
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.
80% of occupied homes in Lake Grove are owner-occupied, 34 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.

In Lake Grove, 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.
