Re: Reconstituting RO/DI Water/ RO Water comes in at 5.5pH
....That's what I've always been told as well.........R/O is 7.0 pH unless
something affects it......but even if something affects it such as breathing
on it etc. if given time........15-20-60 minutes it will drive itself back
to 7.0 unless some buffers or additives are added to REALLY change it!
......but straight R/O water wants to come out and stabilize......if that's
possible, at 7.0 pH.
