The short answer
Housing in Seneca has a median build year of 1990. Where the stock is that new, weak pressure is more often a valve or a fixture than a corroded supply line, and both can be checked before anything is assumed.

Seneca has 15,492 occupied homes across 3 ZIP codes. Across all its housing, vacant units included, the median build year is 1990 — 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 1990 tells you about the pipe in Seneca
Housing of this vintage generally means copper as standard and the last of the polybutylene, which stopped being installed in 1995. Pressure complaints in houses this age are more often about the pressure-reducing valve drifting out of adjustment than about the pipe. More on 1990s supply pipe.
69% of occupied homes in Seneca are owner-occupied, which is about the SC figure of 73% once the survey’s margin of error is allowed for. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Seneca ZIP codes is $68,610, 5% above the SC median of $65,603.

Housing this new in Seneca 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.
