Low Water Pressure in Chantilly, Virginia 20151

Free to homeowners in Chantilly — the contractor pays us for the introduction, you never do.
The short answer
The median build year in Chantilly is 1996, 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.

Chantilly has 18,024 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1996 — 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 1996 tells you about the pipe in Chantilly
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.
82% of occupied homes in Chantilly are owner-occupied, 16 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.

In Chantilly the first check is how many taps are affected, and on housing of this age a single weak one is the common case — an aerator or a supply stop, not the system. Normal supply is 45–80 psi; under 40 psi is low, and a gauge tells you in a minute. Whole house is a call; one tap is not.
