The short answer
With a median build year of 1957, Plainview sits in the era when supply pipe was commonly galvanized steel. That matters because steel loses bore everywhere at once, so a whole-house symptom is ordinary there and a single weak tap is the odd one.

What 1957 tells you about the pipe in Plainview
Housing of this vintage generally means galvanized steel still the norm, with copper appearing towards the end of the decade. A house from these years may have had part of its supply replaced and part left alone, which is why pressure can be fine in one bathroom and poor in another. More on 1950s supply pipe.
93% of occupied homes in Plainview are owner-occupied, 47 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.

Start in Plainview by running the taps one at a time. Where the housing is this old, a single weak fixture is the more interesting finding, because it means the rest of the system is still delivering and something local is not. Normal supply is 45–80 psi; under 40 psi is low. Test it, then decide: whole house is a call, one tap is five minutes.
