The short answer
Commack has a median build year of 1964 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.

Commack has 9,189 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1964 — 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 1964 tells you about the pipe in Commack
Housing of this vintage generally means the changeover years. Copper is common by now but galvanized is still in the ground and in the walls, so what matters is not the build year but which sections were ever replaced. A pressure test at the outside tap tells you more than the age does. More on 1960s supply pipe.
93% of occupied homes in Commack are owner-occupied, 46 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.
