The short answer
The median build year in Captain Cook is 1986, 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.

Captain Cook has 2,579 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1986 — 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 1986 tells you about the pipe in Captain Cook
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.

In Captain Cook, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
