What 1977 tells you about the pipe in Amherst
Housing of this vintage generally means copper as the usual supply material, so corrosion narrowing the pipe is far less likely. In houses of this era a whole-house pressure drop points at the pressure-reducing valve, the main shut-off, or the supply side of the meter rather than at the pipe itself. More on 1970s supply pipe.
91% of occupied homes in Amherst are owner-occupied, 4 points above the NH figure of 87%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Amherst ZIP codes is $155,125, 51% above the NH median of $102,662.
Before calling anyone in Amherst, 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.
