We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Steve Walker"
saying something like:

You have mains pressure at 100psi, eg nearly 7bar?
That sounds extraordinarily high to me, but IANAP

My supply pressure is way above that during the small hours. A pressure
regulator is an absolute must around here - at the bottom of a 500'
hill, on top of which a reservoir/pumping station sits.

For years, I've wondered why the Council doesn't fit pressure regulators
in the main supplies, as they're forever digging up mains to repair
them. I suppose that's too easy.
