Its just occurred to me that I've got this RO unit which came with a freshwater tank a few years ago. Problem is... I've no idea what GPD it is... or anything about it for that matter! I haven't got a wrench so i can't get it open to see if there are any labels on the inside about what membranes it has in it.
Can someone advise me on what to do to get it up and running... or whether it looks usable?
Also, is the units GPD determined by the membranes or is it something else that determines that too? If I get 100gpd membranes then will it make it a 100gpd RO unit?
I will need a booster pump and tubing but beyond that im a bit unsure.
Thanks in advance!
