The short answer
With a median build year of 1990, Reston 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.

Reston has 29,047 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 Reston
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.
61% of occupied homes in Reston are owner-occupied, 5 points below the VA figure of 67%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Housing this new in Reston 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.
