Re: RO questions

I just got a 4-stage 50 gpd RO/DI unit. Can I put a 75 gpd RO membrane in it when I replace it, and then it is suddenly a 75 gpd unit? Or is there more to that than just the membrane?

Might want to check your RO number again - it has to be higher than 3. At 3 that would mean your membrane has a 99.4% rejection rate -- unlikely.
