The short answer
Fairfax has a median build year of 1985 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.

Fairfax has 61,521 occupied homes across 5 ZIP codes. Across all its housing, vacant units included, the median build year is 1985 — 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 1985 tells you about the pipe in Fairfax
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.
