Down the Drain

Episode DCON-201H

It may seem that the gunk we send down the drain or flush down the toilet just magically disappears, but there is some science to making it go away. We'll find out how garbage disposals are made and tested, see how Roto-Rooter tests their equipment with diapers and wooden dowels, and visit a water treatment plant to find out how microbes clean your water. Finally Matt tests one of the most powerful drain cleaners of all - as he clears lumber, roots, and concrete from pipes with a water jet!
