That waste with the RO unit is tough. We have a drought warning so I don't know if I want to do that. If I lose like a 2:1 ratio that would be a terrible waste. I wonder if there is a way to set the unit up outside and divert the waste water back into the house system while keeping like a 55 gallon drum with a float tube full of RO water.
That sounds like an expense though. Maybe I will just start getting it delivered or something.
