The significantly more heavy-duty 50-foot Manual Feed Drain Cleaning Drum costs $299.99, while the 50-foot Automatic-Feed Drain Cleaning Drum Machine will set you back a whopping $399.99.

You just need a pipe wrench, a 50- or 100-foot drain-cleaning snake, and a great pair of gloves. There are plenty of videos on YouTube that show you how to use a manual drain-cleaning snake.

Eventually, though, there'll be a heavy-duty obstruction that no amount of Drano can clear, forcing you to run a drain snake through the overflow, like the Baceyiou 25-Foot Drain Auger.
