Water is piped in similar to electricity. A main water lines has a lot of pressure because *insert number* of houses are using it, when that main line is branched, they can install a pressure regulator that only allows…1000 psi (a guess) for that brand based on that neighborhood. Each brand after that may be 200 for a few houses. Either before or after your personal water tap is a pressure regulator that is regulating pressure to your home to 50 PSI.
With power lines, some may be 500,000 volts. By the time is it ran through *insert number* of transformers, it’s only 240 volts.
