The short answer
The median build year in Kapolei is 1999, recent enough that the pipe itself is rarely the cause. On housing this age a house-wide drop more often turns out to be the pressure-reducing valve, and a single weak tap is usually the aerator on that fixture.

In Kapolei the first check is how many taps are affected, and on housing of this age a single weak one is the common case — an aerator or a supply stop, not the system. Normal supply is 45–80 psi; under 40 psi is low, and a gauge tells you in a minute. Whole house is a call; one tap is not.
