You can never tell, water come from different sources. Go ten miles from here and you are in a different water authority.

[EandM]

Mine is 300 out of the mains
My well is 70
My ground water / uv drinking supply is 128
and the rainwater we harvest is between 11-30.

Best local water is 66 and runs out of a hill into a cattle trough.

I've had over 450 from our tap. Came out in block form so it did!   

Seriously though, 340 is the lowest I've seen it, down to about 20 after RO then big fat zero through the jets.
