The domestic RO systems put pressure on the clean water output and don't have recovery systems for brine pressure? What? My only experience with RO systems are on sailboats, where a brine pressure recovery system is the only way to get the power down, and the water trickles into the tank under low pressure from where it is pumped out.

The linked system above just sends the unfiltered tap water down the drain. I have had two iterations of the GE system and it says so in the manual, for instance. I am not sure about other brands and their systems.

Most in-home systems sold today drain to waste without any attempt at recovery to keep manufacturing costs low.
