Today I measured my incoming mains water pressure to be a little over 10
bar. About 145 PSI. About 100 metres "head"

Quite honestly I was surprised because instinctively I would have
expected it to be somewhat lower. What is normal though? Is 10 bar unusual?

It's never especially bothered me because I have an IMI pressure
regulator taking the in-house pressure down to about 3 bar....however
the regulator started playing up recently causing the in house static
pressure to increase a lot which could be quite alarming when filling a
kettle.

The regulator is now fixed....and I am just curious.
I'd expect 2-4 bar.
