The short answer
Housing in San Gabriel has a median build year of 1958. On stock that old a house-wide pressure drop is the expected finding rather than a surprising one, because galvanized steel narrows from the inside. The figure dates the housing, not the pipe in any particular house.

San Gabriel has 20,086 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1958 — 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.

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.San Gabriel sits 13 years older than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 90% of them, and by number of homes it ranks 95th.
What 1958 tells you about the pipe in San Gabriel
Housing of this vintage generally means galvanized steel still the norm, with copper appearing towards the end of the decade. A house from these years may have had part of its supply replaced and part left alone, which is why pressure can be fine in one bathroom and poor in another. More on 1950s supply pipe.
51% of occupied homes in San Gabriel are owner-occupied, which is about the CA figure of 53% once the survey’s margin of error is allowed for. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In a town of this vintage the first question in San Gabriel is still how many taps are weak, and the answer usually comes back "all of them" — which points at the supply rather than at any fixture. Normal is 45–80 psi, under 40 psi is low, and a gauge settles it in a minute. Whole house is worth a call; one tap is usually yours to fix.
