Well think about it. We used to drink right from the streams. Drinking pure ro water is only supposed to be bad for u cause it's soo pure that the theory is that it will take as much outta ur body as good it would do.
As for drinking the waste water. Well yea the stuff that didn't go through the membrane is concentrated, but my tds meter sais that my waste is only in the 500's. Well national standards are something like 500 isn't it? So it's not that far outside the "national safe range". I personally wouldn't worry about it.
As for the kidney stones, been there and done that more than twice. Not fun. Doc said that no amount of water good or bad canhelp. I was instructed to cut out the sodas and incorperate as much lemon juice into my diet as possible. Supposedly that's about the only natural solvent for the solids that collect in the kidneys.
One thing that I'm not sure about is at what point the flouride gets taken out of the water. I don't know if it's getting trapped by the charcol or if that's something that the ro membrane handles. I would ges not the membrane. Ifthats the case then ok. But if something like the flouride or chlorine or chloramines are concentrated in the waste, well then I would think twice about drinking it.
