The short answer
The median build year in Alto Pass is 1979, 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.

Alto Pass has 298 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1979 — 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 1979 tells you about the pipe in Alto Pass
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.
79% of occupied homes in Alto Pass are owner-occupied, 15 points above the IL figure of 64%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
