Water saving................

[woodcarver]

Hey Steve . The FAQ you are referring to applies to their regular R.O. systems. You need to look up their zero waste model . As it says the waste is fed back into the hot water plumbing so NO water goes down the drain.
As Chad pointed out it is a very simple concept but nice to see it on the market and could be a consideration especially for someone without R.O. and contemplating purchase.
