R/O Water Storage Question

[mike31154]

No worries, I have read other folks post that due to the very pure nature of RODI water, it has a tendency to be very aggressive in trying to absorb any kind of material it comes into contact with, including air, causing the TDS to naturally rise over a period of time. I'm just repeating info I have read in that regard, so no scientific evidence to back it up, but it does seem to make sense.
