Septic safe toilet paper: how to choose it

Updated October 2026 · By the Septic Numbers team · How we estimate

Short answer

Septic safe toilet paper is paper that breaks apart quickly in water. Look for 1-ply or recycled paper, or rolls labeled septic safe, and skip thick quilted or heavily scented rolls. A simple jar test at home shows which brand breaks down fastest. And only toilet paper should go down the toilet: never wipes, paper towels or tissues.

The 2-minute jar test

  1. Put a few squares of each brand into separate jars.
  2. Fill each jar most of the way with water and close the lid.
  3. Shake each jar hard for a few seconds, like a flush.
  4. Check which paper has broken into small bits. The fastest is the best for your system.

Even products labeled "septic safe" vary, so testing is worth the two minutes.

What never goes down the toilet

The EPA's rule is simple: only flush human waste and toilet paper. Its never-flush list includes:

  • Non-flushable wipes, such as baby wipes and other wet wipes
  • Paper towels
  • Feminine hygiene products
  • Cooking grease or oil, and coffee grounds
  • Cat litter, dental floss and cigarette butts
  • Household chemicals such as gasoline, oil, pesticides, antifreeze and paint

Septic companies add "flushable" wipes and facial tissues to that list: both are made to hold together when wet.

Solids that don't break down fill the tank faster and can reach the drain field. See how often to pump to stay ahead of it.

Frequently asked questions

Is 2-ply toilet paper bad for septic systems?

Thicker, multi-ply paper takes longer to break down and can clump in pipes or the tank. It is not banned, but thinner paper is safer. Test your brand with the jar test.

Are flushable wipes septic safe?

Septic companies advise against them: many 'flushable' wipes don't break down the way toilet paper does and can sit in the tank or snag in pipes. The EPA's own rule is to flush only human waste and toilet paper.

Is recycled toilet paper better for septic?

Generally yes. Recycled paper has shorter fibers, which break apart more easily in water.

Can I flush paper towels or tissues?

No. The EPA lists paper towels among items never to flush, and septic companies note both towels and tissues are made to stay strong when wet.
