I never had problems with flipping it over. My problem was after it was upright. The plug-in wouldn't fit right and it overflowed the catch pan. I had one last winter; after 2 months of either no water or ice, I returned it. I bought a bird bath heater and put it in a 5-gallon bucket. no problem there. I might buy one of the bottom heaters for my metal waters to see if that's any better.
