Can You Flush Tissues in a Septic System?

Published in Septic Systems 2 mins read

No, you should not flush tissues in a septic system.

Tissues, especially facial tissues, are not designed to break down as quickly as toilet paper. This can lead to several problems within a septic system:

Problems Caused by Flushing Tissues

  • Clogs: Tissues don't disintegrate easily, leading to clogs in the pipes connecting your toilet to the septic tank. They can also clog the inlet baffle of the septic tank itself.
  • Septic Tank Overload: Because they break down slowly, tissues accumulate in the septic tank, reducing its capacity and potentially leading to backups into your home.
  • Drainfield Issues: Undigested tissues can make their way into the drainfield, clogging the soil and preventing proper wastewater filtration. This can lead to costly repairs or even drainfield failure.
  • Reduced Septic System Lifespan: Flushing tissues regularly can significantly shorten the lifespan of your septic system by causing undue strain and increasing the frequency of required maintenance.

What Can You Flush in a Septic System?

The general rule of thumb for septic systems is to only flush the "Three P's":

  • Pee
  • Poo
  • Toilet Paper

Even with toilet paper, it's best to use septic-safe varieties that break down quickly. Avoid using excessive amounts.

Alternative Disposal Methods

Instead of flushing tissues, dispose of them in a trash can. This simple change can significantly improve the health and longevity of your septic system.
