The short answer
Housing in Old Westbury runs to a median build year of 1969. Pipe of that era fails in more than one way, so the useful first step is counting weak taps: every tap points at the supply, one tap points at that fixture.

Old Westbury has 1,011 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1969 — 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 this site is
PressureTrace is a referral service, not a plumbing contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We do not perform plumbing work, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.Old Westbury sits 6 years newer than the NY median of 1963. Of the 364 NY towns we route calls in, its housing is older than 35% of them, and by number of homes it ranks 279th.
What 1969 tells you about the pipe in Old Westbury
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.
94% of occupied homes in Old Westbury are owner-occupied, 48 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 Old Westbury, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
