Oceanus Posted July 26, 2014 Share Posted July 26, 2014 What is your TDS? And are you using a food grade trash bin? Like the Brute? Link to comment
knives2886 Posted July 26, 2014 Author Share Posted July 26, 2014 tds is 3 and no its in a utility room with the lights off except when doing laundry Link to comment
farkwar Posted July 26, 2014 Share Posted July 26, 2014 Get a brute with lid. Or better, a FDA rated potable water holding tank like Norwesco with a lid. If youre growing algae (much worse than a bacteria slime coat) you have nutrients in your water. All three, nitrate, phosphate, and potassium. Link to comment

nibor Posted July 28, 2014 Share Posted July 28, 2014 You are better off making water in bigger batches. When your RODI first starts up, the RO water is not so pure (TDS creep). After producing a little water, the TDS drops as the impurities are carried away from the product side of the membrane. Using a float valve like this makes the system produce lots of little batches of higher TDS water. This will hugely reduce the life of your DI. If your RODI TDS is three, it is already due for replacement. Link to comment
knives2886 Posted July 28, 2014 Author Share Posted July 28, 2014 ok so ill just turn it all on a day befre waterchanges to help that issue and ill replace filters Link to comment
AZDesertRat Posted July 29, 2014 Share Posted July 29, 2014 And keep it tightly sealed so contaminants do not enter the water. What is the temperature in that room? RO membranes do not like anything over 113 degrees nor does DI. Link to comment
