What 2006 tells you about the pipe in Ashburn
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.
74% of occupied homes in Ashburn are owner-occupied, 7 points above 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 Ashburn 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.
