The short answer
Lompoc has a median build year of 1974 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.
Source: US Census Bureau, American Community Survey 5-year estimates, table B25035.
Lompoc has 18,135 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1974 — 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 this site is
PressureTrace is a referral service, not a plumbing contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We do not perform plumbing work, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.Lompoc sits 3 years newer than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 44% of them, and by number of homes it ranks 107th.
What 1974 tells you about the pipe in Lompoc
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
56% of occupied homes in Lompoc are owner-occupied, 3 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 Lompoc, 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.
