The short answer
With a median build year of 1941, Malverne 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 1941 tells you about the pipe in Malverne
Housing of this vintage generally means galvanized steel as standard, and at this age the inside diameter of a half-inch line can be materially narrower than it was when it was fitted. The classic sign is that pressure is worst at the fixtures furthest from where the water comes in. More on 1940s supply pipe.
95% of occupied homes in Malverne are owner-occupied, 49 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.

In a town of this vintage the first question in Malverne is still how many taps are weak, and the answer usually comes back "all of them" — which points at the supply rather than at any fixture. Normal is 45–80 psi, under 40 psi is low, and a gauge settles it in a minute. Whole house is worth a call; one tap is usually yours to fix.
