The short answer
The median build year in Boise is 1984, 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.
Boise has 109,780 occupied homes across 28 ZIP codes. Across all its housing, vacant units included, the median build year is 1984 — 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.Boise sits 4 years newer than the ID median of 1980. Of the 30 ID towns we route calls in, its housing is older than 47% of them, and by number of homes it ranks 1st.
What 1984 tells you about the pipe in Boise
Housing of this vintage generally means copper throughout in most cases, with polybutylene fitted in some homes built from the late seventies onward. Polybutylene was discontinued in the mid-nineties and is worth identifying, because its failures are sudden rather than gradual. More on 1980s supply pipe.
66% of occupied homes in Boise are owner-occupied, 7 points below the ID 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 Boise ZIP codes is $82,586, 12% above the ID median of $73,830.

In Boise, 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.
