For you people that are using your R/O units for drinking - are you also sanitizing the R/O unit at least every 6 months? 
If not, you should start. Bacteria will accumulate in your systems. 
We have a separate R/O unit  for our drinking water here (we're on a well) and the instructions state that sanitization every 3 - 6 months is recommended.
