When I run my RO unit, I just let the rejected water run right down the sink....for 2 hours. I net just under 6 gallons of good water in that time frame. I imagine it is much the same way for a lot of us. Don't you think that's pretty wasteful? I mean I certainly don't have any suggestions to remedy this, so I don't really have a point. What do you do with your rejected RO water? Do you have any good ideas to recycle it somehow? Is there something I am missing with regards to how water flows through our systems and such?
