The short answer

Housing in Mill Valley runs to a median build year of 1961. 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.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25035.

Mill Valley has 12,534 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1961 — 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.

Mill Valley sits 10 years older than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 82% of them, and by number of homes it ranks 149th.

What 1961 tells you about the pipe in Mill Valley

Housing of this vintage generally means the changeover years. Copper is common by now but galvanized is still in the ground and in the walls, so what matters is not the build year but which sections were ever replaced. A pressure test at the outside tap tells you more than the age does. More on 1960s supply pipe.

67% of occupied homes in Mill Valley are owner-occupied, 14 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 Mill Valley ZIP codes is $210,217, 101% above the CA median of $104,737.

Before calling anyone in Mill Valley, 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.
