"What comes out of you and toilet paper." These are the only things that should be flushed down the toilet. This informative and entertaining video shows in a great visual way what happens to some common bathroom throw-aways when they're flushed down the toilet - so-called "flushable" things like kitty litter or baby wipes. In a demonstration by a sewage pre-treatment technician, wastewater customers (all of us) can see what happens when dental floss, facial tissue, cotton swabs and feminine napkins are sent through the wastewater system.
