The short answer
Bethesda has a median build year of 1968 across its housing. That is late enough for copper and early enough for polybutylene in places, which is why the pattern of the symptom is worth establishing before anybody is called out.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25035.
Bethesda has 34,212 occupied homes across 6 ZIP codes. Across all its housing, vacant units included, the median build year is 1968 — 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 1968 tells you about the pipe in Bethesda
Housing of this vintage generally means the changeover years. Copper is common by now but galvanized is still in the ground and in the walls, so what matters is not the build year but which sections were ever replaced. A pressure test at the outside tap tells you more than the age does. More on 1960s supply pipe.
70% of occupied homes in Bethesda 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.
Median household income across Bethesda ZIP codes is $231,284, 94% above the MD median of $119,156.

The first thing to establish in Bethesda is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
