Just got a tds meter, tested our tap water and it's reading at 064. Our fridge water is reading at 042. I read online that average tap water is between 140-400. We haven't hooked our RO/DI up yet.. had to order another hookup for it. Should the RO/DI read 000 before it's ready to go in our tank? Is our other water almost pure?
