The short answer
Housing in Rockville runs to a median build year of 1975. Pipe of that era fails in more than one way, so the useful first step is counting weak taps: every tap points at the supply, one tap points at that fixture.

Rockville has 57,555 occupied homes across 4 ZIP codes. Across all its housing, vacant units included, the median build year is 1975 — 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 this site is

Contractors are required to hold whatever credential their state or municipality demands.

We do not perform plumbing work, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.Rockville sits 7 years older than the MD median of 1982. Of the 159 MD towns we route calls in, its housing is older than 76% of them, and by number of homes it ranks 3rd.
What 1975 tells you about the pipe in Rockville
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
54% of occupied homes in Rockville are owner-occupied, 15 points below the MD figure of 69%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Rockville ZIP codes is $122,093.

Before calling anyone in Rockville, check whether every tap is weak or just one. 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.
