PSA: don’t flush tampons.
They are not designed to be flushed, and the vast majority of plumbing and sewage systems aren’t designed to process them. Even if they make it down your toilet, they can build up in your pipes or septic tank and cause expensive damage and disgusting, smelly backups. Waste products and toilet paper are all that should be flushed - in some places, even toilet paper is a no-go. Other products marketed as “flushable” are just trying to get you to buy them.
Menstrual products are expensive, but having your plumbing replaced because it’s become choked on tampons and is now overflowing through every drain in the building is way more expensive. Please dispose of them responsibly.
