I was told years ago by a plumber that you "don't really need" an airgap for reverse osmosis filters (I was complaining about the drain noise). He told me how to hook the hoses up to eliminate the airgap, which I won't go into here because my question is: is this safe? Is this airgap really only there for when my SEWER backs up into my sink? If so I think I can live without it! Or does a sink clog backing up present some sort of flowback danger to my RO unit? Thanks in advance.
