The short answer
The median build year in Frederick is 1992, 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.

Frederick has 56,763 occupied homes across 4 ZIP codes. Across all its housing, vacant units included, the median build year is 1992 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

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.
68% of occupied homes in Frederick are owner-occupied, which is about the MD figure of 69% 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.

Before calling anyone in Frederick, check whether every tap is weak or just one. On housing this recent a house-wide drop more often turns out to be the pressure-reducing valve or the meter than the pipe itself. Normal supply is 45–80 psi and under 40 psi is low — how to test it in a minute. Whole house is a supply problem worth a call; one tap is usually a five-minute job you can do yourself.
