The short answer
With a median build year of 2007, San Tan Valley is newer housing, and newer housing moves the likely cause away from the pipe. A pressure-reducing valve explains a whole-house drop more often than the supply does at that age.

What 2007 tells you about the pipe in San Tan Valley
Housing of this vintage generally means copper and the first widespread PEX. Neither corrodes closed, so a genuine whole-house pressure drop in a house of this age is almost always a valve, the meter, or the supply into the property — not the plumbing inside it. More on 2000s supply pipe.
82% of occupied homes in San Tan Valley are owner-occupied, 16 points above the AZ figure of 66%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Housing this new in San Tan Valley rarely has a materials problem, so the useful first step is the same one but the likely answer is different: count the weak taps, and if it is all of them look at the valve rather than the plumbing. Normal is 45–80 psi, under 40 psi is low — how to check. Whole house, or just the one.
