Quite--like double. I'm extremely surprised they've not blown out
toilet valves, etc., routinely at those pressures altho perhaps the
secret has been that restriction dropped pressure when running so only
static pressure has/is so terribly high.

It's definitely time for the PRV...

82PSI is considered normal domestic water supply pressure here in
Waterloo Region (Ontario Canada) and 90 is NOT out of the ordinary.
A 150 ft tower will provide 65psi by gravity alone to houses built at
the same level. If the tower is on a hill 50 feet higher, ot a house
is in a valley 50 feet lower, you have over 85psi. Pressure reducing
valves are virtually unheard of here.
