Tampons can go down most toilet systems, but they can cause numerous issues from there. Unlike toilet paper, tampons are not designed to disintegrate in water. This means that they can get stuck in the drain and cause backups or impede wastewater facility functions.
There are many objects that people assume can be flushed that cannot. Among them are paper towels, condoms and tampons. In the past, many manufacturers have told consumers that tampons can be flushed, but they merely mean that the tampons fit through the drains. Tampons often get caught in sewer piping. While they do not always cause an immediate clog, things can build up around the caught tampon, and that can cause a clog. Tampons that do not clog the toilets they go down are often retrieved at wastewater facilities and then disposed of in landfill.
