The short answer
Housing in New Castle has a median build year of 1955. On stock that old a house-wide pressure drop is the expected finding rather than a surprising one, because galvanized steel narrows from the inside. The figure dates the housing, not the pipe in any particular house.

Of the 303 PA towns we route calls in, its housing is older than 89% of them, and by number of homes it ranks 16th.
What 1955 tells you about the pipe in New Castle
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.
72% of occupied homes in New Castle are owner-occupied, 4 points above the PA figure of 67%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Before calling anyone in New Castle, check whether every tap is weak or just one. On housing this old a whole-house drop is the expected finding, because galvanized steel loses bore from the inside and loses it everywhere at once. Normal supply is 45–80 psi and under 40 psi is low — how to test it in a minute. Whole house is a supply problem worth a call; one tap is usually a five-minute job you can do yourself.
