The short answer
Fairfield has a median build year of 1989 across its housing. That is late enough for copper and early enough for polybutylene in places, which is why the pattern of the symptom is worth establishing before anybody is called out.

Fairfield has 3,193 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1989 — 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.Fairfield sits 15 years newer than the PA median of 1974. Of the 303 PA towns we route calls in, its housing is older than 9% of them, and by number of homes it ranks 147th.
What 1989 tells you about the pipe in Fairfield
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.
88% of occupied homes in Fairfield are owner-occupied, 21 points above the PA figure of 67%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Before calling anyone in Fairfield, 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.
