The short answer

Wilmington has a median build year of 1960 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.

Wilmington has 14,959 occupied homes across 2 ZIP codes. Across all its housing, vacant units included, the median build year is 1960 — 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.

Wilmington sits 11 years older than the CA median of 1971. Of the 257 CA towns we route calls in, its housing is older than 86% of them, and by number of homes it ranks 131st.

What 1960 tells you about the pipe in Wilmington

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.

36% of occupied homes in Wilmington are owner-occupied, 17 points below 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 Wilmington ZIP codes is $61,440, 41% below the CA median of $104,737.

Source: US Census Bureau, American Community Survey 5-year estimates, 2023 release — tables B25003 (occupied units), B25035 (all units) and B19013 (households). How these are aggregated.

In Wilmington, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
