Free to homeowners in Williamston — the contractor pays us for the introduction, you never do.
The short answer
The median build year in Williamston is 1990, recent enough that the pipe itself is rarely the cause. On housing this age a house-wide drop more often turns out to be the pressure-reducing valve, and a single weak tap is usually the aerator on that fixture.

Williamston has 5,798 occupied homes across 1 ZIP code. 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 Williamston
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.
76% of occupied homes in Williamston 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.

Housing this new in Williamston 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.
