Low Water Pressure in Cambridge, Massachusetts 02138
The typical home here dates from 1950, which predicts the supply pipe. Whole house or one tap, and who to call.
Free to homeowners in Cambridge — the contractor pays us for the introduction, you never do.
The short answer
With a median build year of 1950, Cambridge 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.

Cambridge has 49,732 occupied homes across 5 ZIP codes. Across all its housing, vacant units included, the median build year is 1950 — 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.Cambridge sits 16 years older than the MA median of 1966. Of the 176 MA towns we route calls in, its housing is older than 79% of them, and by number of homes it ranks 2nd.
What 1950 tells you about the pipe in Cambridge
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.
34% of occupied homes in Cambridge are owner-occupied, 26 points below the MA figure of 60%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Before calling anyone in Cambridge, 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.
