The short answer
The median home in Royal dates from 1939 or earlier, which puts galvanized steel supply pipe in the frame: it loses bore from the inside and loses it everywhere at once. Weak pressure at every tap points at the supply, while one weak tap usually points at that fixture.

Royal has 345 occupied homes across 1 ZIP code. Across all its housing, vacant units included, the median build year is 1939 or earlier — 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 a pre-1940 build tells you about the pipe in Royal
Housing of this vintage generally means galvanized steel supply pipe throughout, most of it decades past the point where the zinc lining has gone and rust has begun closing the bore from the inside. In houses this old the pressure loss is usually gradual rather than sudden, and it affects the whole house rather than one tap. More on pre-1940 supply pipe.

Before calling anyone in Royal, check whether every tap is weak or just one. On housing this old a whole-house drop is the expected finding, because galvanized steel loses bore from the inside and loses it everywhere at once. 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.
