I recently installed a brand new RODI system and my in line tds meter is reading 7 , I read that initially the reading can be high but eventually goes to 0. It’s been a week and I’ve run over 20 gallons of water through the system and it’s still reading 6-7 tds. Is this normal? When ca. I expect it to read zero and how can I know if the water is safe to use ?
My old RODI never read above 1-2 and I would change the filters and resins when it went above 0.
