Not necessarily, using higher pressure on mains (not just water) and a
regulator at the point of utilization is a classic design method to
insure there is always constant pressure at the point of utilization.





Living with a well, I found that plumbing with 1" copper helps a lot. My

Yep. It is impossible to design a city distribution system for equal
pressure at all elevations. Then there is the desire for high
pressure at hydrants for fire suppression vice reasonable pressure in
a residence.

Thus it is, at least here, up to the people living in the excessive
high pressure zones to install a pressure reducer.
