Thanks for all the information you have posed about the J.E. machine.
I have seen Alkaline Water pH 9.7, but yet have an ORP of +230. Yet some ionizers as I have seen can get water of upto -800 ORP. This water might not have the adverse effects in the kidneys as it does not have bicarbonates in it.
I know you have said that JE machine 'runoff' has an alkiline pH, but could this be because you have hard water and the runoff is not really distilled? what is your water pH prior to going into the machine?
Do you know what is the ORP prior and after going into the machine, through the distiller and runoff part? That for me is an interesting questions.
