I recently acquired a used ionizing water machine for free, brand name RadiRedWater (Japanese).
I connected the machine to the tap water through a water filter (the RadiRedWater also has an internal filter) and measured the pH of the processed water.
pH of input water = <6.8 (slightly acidic).
pH of processed water = >8.2 (alkaline).
So the machine does indeed change the water pH.
By the way, the pH of local bottled water = 7.7 (slightly alkaline).
Whether drinking alkaline water has any effect on PCa is another question. I am not qualified to discuss the chemical and biological arguements one way or t'other. However, personally I don't think that standard medicine has the answer as well, so I don't mind trying alternative remedies.
