That's too easy! thank you sir. I have a couple more questions, others may want to chime in.

I have some extra parts laying around and I've seen people do this. What is the point of running two RO membranes and how do you hook them up? Is it just refiltering the waste water from the first membrane so you have less waste? Also, if I ran two canisters with DI resin, in theory it should last twice as long, right? Sorry for the dumb questions, just curious to see if I can make a frankenRO unit and if it'd be worth it.
