The short answer
With a median build year of 1998, Round Rock 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 1998 tells you about the pipe in Round Rock
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.
64% of occupied homes in Round Rock are owner-occupied, 7 points above the TX figure of 57%. It matters here because the run between the meter and the house belongs to the property owner, not the utility.

Housing this new in Round Rock 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.
