    I am thinking the pipe would have to have the bottom end in a bucket of liquid for that to work. Then the bucket could over flow and spill the liquid on the ground or be large enough to hold all it.

    Would you call that a coaxial siphon?

    Not if the drainpipe had a P trap like your bathtub or kitchen sink
    Never try to tell me it can't be done

    If you saw the protruding outlet off at the bottom, this will work without the bottle.
    Can anyone give me an example of where a protruding outlet like this would be used? I can’t think of any.

    I would say it's probably new construction this is the rough in drain for a tub or shower with P trap. It rained and the building was not dried in yet. This will drain off the majority of the water so the rest can be vacuumed up then dried.

    I have my parts washer tank set up with the protruding drain like that. When I am washing dirty parts, the solvent drains through the elevated pipe. This allows most of the dirt to settle on the bottom of the basin. After it has settled a while, I can remove the extension to drain the solvent, leaving the dirt behind to scooped out of the basin. Have to let it drain slowly so it does not flush the dirt down.
