The short answer
Port Jefferson has a median build year of 1971 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.

Port Jefferson has 3,628 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1971 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

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.Port Jefferson sits 8 years newer than the NY median of 1963. Of the 364 NY towns we route calls in, its housing is older than 29% of them, and by number of homes it ranks 174th.
What 1971 tells you about the pipe in Port Jefferson
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.
74% of occupied homes in Port Jefferson are owner-occupied, 28 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.
