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.

What are typical plumbing method/materials used in your area?

Everything I've read/heard says that normal DW pressure should be ~60 PSI or less. Personally I like a little higher for better showers, but not sure at what point "a little higher" becomes too much.
