In the early '80s, the Norge Village where I did my laundry as a college student took out its Norge top-loaders and installed White-Westinghouse front loaders. And they did that very thing: they took out all of the standpipes that served the Norges and installed a trough. And they did drain through the floppy rubber hoses. Sometimes those things would flop around like a balloon losing air and spray water everywhere. And sometimes they'd jump out of the trough and drain on the floor. They tried all kinds of things to prevent that from happening; they eventually wound up encasing them in short lengths of PVC pipe.
