My RO unit arrived today and since I can't fill my tank (story in another post) I've been playing with the unit (getting it mounted on the wall etc).
I used the tds meter on just my plain tap water and it was around 375. Then, after letting the RO unit run for 15 minutes I tested it and it was 9. I know if I also had a DI unit the reading would probably be 0, but is 9 typical for just RO?
