The short answer
Housing in Martinez runs to a median build year of 1975. Pipe of that era fails in more than one way, so the useful first step is counting weak taps: every tap points at the supply, one tap points at that fixture.

Martinez has 19,134 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1975 — 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.Martinez sits 4 years newer than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 40% of them, and by number of homes it ranks 101st.
What 1975 tells you about the pipe in Martinez
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.
72% of occupied homes in Martinez are owner-occupied, 19 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.
Median household income across Martinez ZIP codes is $121,023, 16% above the CA median of $104,737.

Before calling anyone in Martinez, check whether every tap is weak or just one. Normal supply is 45–80 psi and under 40 psi is low — how to test it in a minute. Whole house is a supply problem worth a call; one tap is usually a five-minute job you can do yourself.
