Hi folks, I heard recently that there is an R/O unit that produces 1 gallon of water and wastes only one gallon. My question is there such a unit or is this like many other things a myth? If not true what would be the most efficient unit to buy wasting the least amount of water? The unit I have now wastes about ten gallons for every one produced. Another question has anyone used Proper pH 6.5 to reduce the pH and keep it stable? TIA, Jerry F.
