Is it normal for an RO
unit to take a while before the readings from the output water are close to 0? I have had mine running for 2 days and it is not permanently connected under my sink. I hook it up to the hose with an adapter. I have made about 15 gallons so far and my readings are at 12. Is this reading to high to use as top off water? When I test my store bought Publix purified water I get a reading of 1 with my TDS
meter. I hate to use water with a higher reading but if 12 is not considered bad I would like to use it since I have 5 gallons of it made.
