If you live in an old DC rowhouse, you should wrap in TP and throw in the garbage. DO NOT FLUSH.
Our line from the house down to the main sewer line under the street got clogged. We had our plumbers do an emergency snaking, since water was backing up in all our basement drains.
The plumber pulled out a tangle of tampons and sanitary pads the size of a softball. IT WAS DISGUSTING and had caused a total blockage.
