never really been involved with the setting up/process so please forgive me if i sound a bit slow on the take with this.  :

is there a ro system out there that doesnt need waste/drain?

was just wondering.

A reverse osmosis system works by splitting water. Water with sediment waste ect goes down the drain, Water without (or very low amounts) is retained. Therfore the very nature of RO means you need waste for it to work.
