Put trash in a trash can, not the toilet

 

Put trash in the trash can, not the toilet

What does "flushable" really mean? It means that it will fit down the toilet bowl, not that it is safe for sewers or will actually biodegrade in the sewer system. Sewer pipes and treatment plants were only designed to handle toilet paper so when it comes to flushing, the only trash allowed down the toilet should be toilet paper, which disinigrates.

Helpful Hint: Use the four "P's" to help people remember the only things that should be flushed: Pee, Poo, Puke and Paper (toilet paper, that is).

Don't flush trouble - these items belong in the trash can!
