Low Water Pressure in Waltham, MA

Waltham has 25,692 occupied homes across 3 ZIP codes, and the typical one was built in 1967. That year is the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.
Waltham sits 1 year newer than the MA median of 1966. Of the 176 MA towns we route calls in, its housing is older than 49% of them, and by number of homes it ranks 12th.
What 1967 tells you about the pipe in Waltham
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.
49% of occupied homes in Waltham are owner-occupied, 28 points below the MA figure of 77%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Waltham ZIP codes is $114,029, 10% below the MA median of $127,270.
Before calling anyone in Waltham, check whether every tap is weak or just one. 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.
