Product review (3 stars): Only works in some cases.
I managed to make this work but it's not easy.  Dish washers generally come with a drain hose.  Some come with the hose permanently attached and some come with the hose loose.  For the latter, you can substitute this longer hose.  For the former, if you need a really long hose you can attach this to the end of the factory installed hose.  If the two together are too long, you are screwed as you cannot cut this spiral plastic hose.  It cannot be coupled together (and seal) if you do.  When it does work, its a perfect solution.
