Low Water Pressure in Wilmington, Delaware 19801
The typical home here dates from 1957, which predicts the supply pipe. Whole house or one tap, and who to call.
Free to homeowners in Wilmington — the contractor pays us for the introduction, you never do.
The short answer
With a median build year of 1957, Wilmington sits in the era when supply pipe was commonly galvanized steel. That matters because steel loses bore everywhere at once, so a whole-house symptom is ordinary there and a single weak tap is the odd one.

Wilmington has 92,951 occupied homes across 25 ZIP codes. Across all its housing, vacant units included, the median build year is 1957 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

Contractors are required to hold whatever credential their state or municipality demands.

Of the 43 DE towns we route calls in, its housing is older than 95% of them, and by number of homes it ranks 1st.
What 1957 tells you about the pipe in Wilmington
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.
65% of occupied homes in Wilmington are owner-occupied, 7 points below the DE figure of 72%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Before calling anyone in Wilmington, check whether every tap is weak or just one. On housing this old a whole-house drop is the expected finding, because galvanized steel loses bore from the inside and loses it everywhere at once. 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.
