I live in a flat
if i have a RO inside with tank inside (in a store room) i think i'm right in thinking the waste water has to go into a drain.
just looking for clarification that there is no other way. or can i fill barrels- i mean how much waste do you produce for each unit of pure?
also, people use RO with DI polisher, is that right. is just RO on its own not good enough?
cheers, thanks for advice
