The short answer

What 1959 tells you about the pipe in Syosset
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.

Start in Syosset 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.
