The short answer
The median build year in Oyster Bay is 1961, 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.

Oyster Bay has 3,700 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1961 — 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 1961 tells you about the pipe in Oyster Bay
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.
72% of occupied homes in Oyster Bay are owner-occupied, 25 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.
