The short answer
The median build year in Maple Valley is 1997, 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.

Maple Valley has 12,837 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1997 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

Of the 70 WA towns we route calls in, its housing is older than 10% of them, and by number of homes it ranks 27th.
What 1997 tells you about the pipe in Maple Valley
Housing of this vintage generally means copper as standard and the last of the polybutylene, which stopped being installed in 1995. Pressure complaints in houses this age are more often about the pressure-reducing valve drifting out of adjustment than about the pipe. More on 1990s supply pipe.
86% of occupied homes in Maple Valley are owner-occupied, 26 points above the WA figure of 60%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Maple Valley 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.
