The short answer
West Covina has a median build year of 1966 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.
West Covina has 33,082 occupied homes across 3 ZIP codes. Across all its housing, vacant units included, the median build year is 1966 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

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.West Covina sits 5 years older than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 68% of them, and by number of homes it ranks 43rd.
What 1966 tells you about the pipe in West Covina
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.
61% of occupied homes in West Covina are owner-occupied, 8 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 West Covina 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.
