Airplane toilets use an active vacuum instead of a passive siphon, and they are therefore called vacuum toilets. When you flush, it opens a valve in the sewer line, and the vacuum in the line sucks the contents out of the bowl and into a tank.
When flushed, a normal toilet sends waste through a trap, into a waste line, and onto the main drain line to the sewer or septic tank. Because that drain line is below the level of the toilet, gravity pulls the contents of the waste line into it. Itâs the same with sinks and tubs. Macerating toilets (aka upflush toilets), on the other hand, send waste to a macerating unit located behind the toilet or in the wall.
