The short answer
Housing in Fontana runs to a median build year of 1989. 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.

Fontana has 62,789 occupied homes across 5 ZIP codes. Across all its housing, vacant units included, the median build year is 1989 — 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.Fontana sits 18 years newer than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 13% of them, and by number of homes it ranks 13th.
What 1989 tells you about the pipe in Fontana
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.
67% of occupied homes in Fontana 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.

The first thing to establish in Fontana is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
