The short answer
The median build year in New Castle is 1971, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.

What 1971 tells you about the pipe in New Castle
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
