Low Water Pressure in Mckinleyville, California 95519
The typical home here dates from 1991, which predicts the supply pipe. Whole house or one tap, and who to call.

Free to homeowners in Mckinleyville — the contractor pays us for the introduction, you never do.
The short answer
With a median build year of 1991, Mckinleyville is newer housing, and newer housing moves the likely cause away from the pipe. A pressure-reducing valve explains a whole-house drop more often than the supply does at that age.

Of the 257 CA towns we route calls in, its housing is older than 11% of them, and by number of homes it ranks 193rd.
What 1991 tells you about the pipe in Mckinleyville
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.
61% of occupied homes in Mckinleyville are owner-occupied, 8 points above the CA figure of 53%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Mckinleyville 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.
