I run a 75GPD RO and have another RO aswell that i have had to use for parts. Can I use both membranes on one RO like this one? If i can how do i plumb it in ? do i have two waste pipes ?
I know 75GPD is rubbish, but its keeping me going at the moment till i can upgrade. So can i add the other 75 membrane on to make a 150 or am i dreaming ?
