The short answer
With a median build year of 1993, Longmont 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.

What 1993 tells you about the pipe in Longmont
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.
69% of occupied homes in Longmont are owner-occupied, 4 points above the CO figure of 65%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

In Longmont 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.
