There are a number of items that should never be flushed down the toilet. Non-flushable items can cause problems for residential and business sewer lines in the District.

Toilet paper is really the only thing you should be flushing.

You can help by never flushing the following:

  • Wipes of any kind. Including the “flushable” ones.
  • Paper towels and napkins
  • Rags and towels
  • Tampons, pads, or any other feminine products
  • Cat litter or aquarium gravel
  • Syringes and needles
  • Rubber items such as latex gloves and condoms
  • Band-aids
  • Dental floss
  • Q-Tips, cotton balls, cosmetics, and razors
  • Diapers and underwear
  • Prescription medications (learn how to properly dispose of medications HERE)
  • Cleaning sponges, disposable toilet brushes, and disinfecting wipes
  • Gum, cigarette butts, and cigars
  • Grease or oil
