Actually, you should be able to handle that by tapping it into
the sink drain, at the P trap, and just be sure one part is hung
high enough to be higher than the entry point to the drain. You
don't HAVE to run it down thru the floor.
Probably a PITA, but run the hose thru the backs of the
cabinets, or even into a different P trap if there's one around
downstairs; all you need's a place to let some air in. The one
way air trap gizmos also work well, but I also discovered they
leak after awhile from the crud collection, so you want it where
you can get at it easy to check and/or change it out.
But, as you found out, you do need something to allow the
suction to break. Common problem lost of diy-ers run into the
first time. Including me <g>.
