The short answer
Housing in Rock City has a median build year of 1946. 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.

Rock City has 509 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1946 — 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 1946 tells you about the pipe in Rock City
Housing of this vintage generally means galvanized steel as standard, and at this age the inside diameter of a half-inch line can be materially narrower than it was when it was fitted. The classic sign is that pressure is worst at the fixtures furthest from where the water comes in. More on 1940s supply pipe.
90% of occupied homes in Rock City are owner-occupied, 26 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.
Median household income across Rock City ZIP codes is $83,542, 9% below the IL median of $91,306.

In a town of this vintage the first question in Rock City is still how many taps are weak, and the answer usually comes back "all of them" — which points at the supply rather than at any fixture. Normal is 45–80 psi, under 40 psi is low, and a gauge settles it in a minute. Whole house is worth a call; one tap is usually yours to fix.
