I finally got my RO Unit installed a day or so ago. It came with a TDS meter. I checked the RO water...It read 20ppm...but I wasnt really sure how good that was. So I checked the water coming out of the fridge...734! I got busy and didnt get to check the tap. So anyone who questions why we preach RO water so adamently, thats why....the difference in RO and Tap is the same as the difference in tap and river water...Its just not as obvious!
