Free to homeowners in Gresham — the contractor pays us for the introduction, you never do.
The short answer
With a median build year of 1991, Gresham is newer housing, and newer housing moves the likely cause away from the pipe. A pressure-reducing valve explains a whole-house drop more often than the supply does at that age.

Gresham has 1,075 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1991 — 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.Gresham sits exactly on the SC median of 1991. Of the 77 SC towns we route calls in, its housing is older than 51% of them, and by number of homes it ranks 64th.
What 1991 tells you about the pipe in Gresham
Housing of this vintage generally means copper as standard and the last of the polybutylene, which stopped being installed in 1995. Pressure complaints in houses this age are more often about the pressure-reducing valve drifting out of adjustment than about the pipe. More on 1990s supply pipe.
68% of occupied homes in Gresham are owner-occupied, which is about the SC figure of 73% once the survey’s margin of error is allowed for. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Gresham the first check is how many taps are affected, and on housing of this age a single weak one is the common case — an aerator or a supply stop, not the system. Normal supply is 45–80 psi; under 40 psi is low, and a gauge tells you in a minute. Whole house is a call; one tap is not.
