The short answer
The median build year in Dover is 1975, 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.
Dover has 15,021 occupied homes across 3 ZIP codes. Across all its housing, vacant units included, the median build year is 1975 — 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.Dover sits 4 years older than the NH median of 1979. Of the 127 NH towns we route calls in, its housing is older than 76% of them, and by number of homes it ranks 4th.
What 1975 tells you about the pipe in Dover
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.
51% of occupied homes in Dover are owner-occupied, 21 points below the NH figure of 72%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.
Median household income across Dover ZIP codes is $92,793, 10% below the NH median of $102,662.

In Dover, count the weak taps before you do anything else. Every one of them points at the supply; a single one points at that fixture, and the difference decides whether this costs you five minutes or a contractor. Normal supply is 45–80 psi and under 40 psi is low (here is the test). Then: whole house or one tap.
