The short answer
The median build year in Germantown is 1989, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.
Sources: US Census Bureau, American Community Survey 5-year estimates, table B25035; normal and low ranges as published by Grundfos in its homeowner guide to low water pressure.
Germantown has 31,447 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1989 — 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 1989 tells you about the pipe in Germantown
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.

The first thing to establish in Germantown 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.
