>Important to point out that usually these safety systems are entirely physical, distributed, and not connected to the web in any way. So hard to cyber hack, though possible to individually disable somehow.

^^^^^^^^^ Yes. Very much agreed. Multiple physical Safety Systems would need to be disabled in order to allow significant overpressurization. Physical safety systems aren't exactly something you can "hack". Think of a physical padlock. You need a physical key to open the physical padlock - a computer doesn't do shit.

>Zero safety systems after the house meter as far as the lines go. Some plumber or other trade worker, depending on area, instllaed everything after the meter. If there was a high pressure surge that was still within the limits of the meter regulator range that got through to aging pipes or shoddy workmanship, it could have comp’d the lines within the homes. Perhaps that’s why the damage was random and spread out.

That makes sense.
