You mention a drain - do R/O and/or distillation systems need a drain? I figured there would just be some type of part or filter that would occasionally be replaced. There is a drain in an adjacent room, but I doubt it would be practical to run a line to it. I could just punch a hole in the exterior wall and let the water out that way, though.

Filters alone just won't cut it, they leave all kinds of crap behind.

Some RO's need drains and pretty much all distillers need drains.

Distillers don't boil the water all the way down when they make steam, they are left with a brine full of heavy solids and "crap" in the boiling vessel that must be disposed of. Boiling all the way down and not flushing the vessel would eventually ruin the unit due to scaling. Some RO systems use a high-pressure backflush to extend filter and membrane life, when backflushing, the contaminated discharge needs to be disposed of.
