The short answer
With a median build year of 1991, Union Mills 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.

Union Mills has 940 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.

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.

Housing this new in Union Mills rarely has a materials problem, so the useful first step is the same one but the likely answer is different: count the weak taps, and if it is all of them look at the valve rather than the plumbing. Normal is 45–80 psi, under 40 psi is low — how to check. Whole house, or just the one.
