Free to homeowners in Chelsea — the contractor pays us for the introduction, you never do.
The short answer
Housing in Chelsea has a median build year of 1939 or earlier. On stock that old a house-wide pressure drop is the expected finding rather than a surprising one, because galvanized steel narrows from the inside. The figure dates the housing, not the pipe in any particular house.

Chelsea has 13,522 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1939 or earlier — 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.Chelsea sits at least 28 years older than the MA median of 1966. Of the 176 MA towns we route calls in, its housing is older than 99% of them, and by number of homes it ranks 34th.
What a pre-1940 build tells you about the pipe in Chelsea
Housing of this vintage generally means galvanized steel supply pipe throughout, most of it decades past the point where the zinc lining has gone and rust has begun closing the bore from the inside. In houses this old the pressure loss is usually gradual rather than sudden, and it affects the whole house rather than one tap. More on pre-1940 supply pipe.
29% of occupied homes in Chelsea are owner-occupied, 30 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.

In a town of this vintage the first question in Chelsea is still how many taps are weak, and the answer usually comes back "all of them" — which points at the supply rather than at any fixture. Normal is 45–80 psi, under 40 psi is low, and a gauge settles it in a minute. Whole house is worth a call; one tap is usually yours to fix.
