The short answer
Columbia has a median build year of 1984 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.

Columbia has 39,859 occupied homes across 3 ZIP codes. Across all its housing, vacant units included, the median build year is 1984 — 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 1984 tells you about the pipe in Columbia
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.
