The short answer
The median home in Charlestown dates from 1939 or earlier, which puts galvanized steel supply pipe in the frame: it loses bore from the inside and loses it everywhere at once. Weak pressure at every tap points at the supply, while one weak tap usually points at that fixture.

Charlestown has 9,389 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.
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.Charlestown 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 64th.
What a pre-1940 build tells you about the pipe in Charlestown
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.
50% of occupied homes in Charlestown are owner-occupied, 10 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.

Start in Charlestown by running the taps one at a time. Where the housing is this old, a single weak fixture is the more interesting finding, because it means the rest of the system is still delivering and something local is not. Normal supply is 45–80 psi; under 40 psi is low. Test it, then decide: whole house is a call, one tap is five minutes.
