Acidic water taste 22ppm, solutions?
We asked the water purifier technician to set the ppm of water at 80-100. He did it and it was 91 ppm, but after 4 weeks the Tds came down to 22 ppm and the water is tasting acidic. What to do? Does the tds become low again if the tds controller is set again at 80-100 ppm?
It's an RO water purifier
