What 1977 tells you about the pipe in Machesney Park
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.
80% of occupied homes in Machesney Park are owner-occupied, 16 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.

In Machesney Park, 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.
