The short answer
Walnut Grove has a median build year of 1977 across its housing. That is late enough for copper and early enough for polybutylene in places, which is why the pattern of the symptom is worth establishing before anybody is called out.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25035.
Walnut Grove has 1,131 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1977 — 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 1977 tells you about the pipe in Walnut Grove
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.
86% of occupied homes in Walnut Grove are owner-occupied, 24 points above the MO figure of 61%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Walnut Grove ZIP codes is $56,484, 9% below the MO median of $61,964.

The first thing to establish in Walnut Grove is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
