The short answer
The median build year in Waltham is 1967, which is copper territory and sometimes copper with polybutylene in part of the run. Normal supply is 45 to 80 psi and under 40 psi is low, so a gauge on an outside tap settles whether this is a supply problem at all.
Sources: US Census Bureau, American Community Survey 5-year estimates, table B25035; normal and low ranges as published by Grundfos in its homeowner guide to low water pressure.
Waltham has 25,692 occupied homes across 3 ZIP codes. Across all its housing, vacant units included, the median build year is 1967 — the most useful single fact for working out why the water pressure is weak, because it predicts what the supply pipe is made of.

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, 11 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.
Median household income across Waltham ZIP codes is $114,029, 10% below the MA median of $127,270.

The first thing to establish in Waltham is whether the problem is the house or one fixture, and it takes two minutes of walking around. Housing of this era can be copper throughout or copper with polybutylene in part, and the two fail differently enough that the pattern matters. Normal is 45–80 psi, under 40 psi is low — test it. Whole house is a call; one tap usually is not.
