Can you flush facial tissue (kleenex) with a septic tank?
The short answer for facial tissue (kleenex) and a septic tank: trash. Facial tissue is treated with wet-strength chemicals so it holds together when wet — the opposite of what you want in a septic tank.
It breaks down much more slowly than toilet paper, adding to the solids the tank has to hold. Toss used facial tissue in the trash rather than the toilet.
- Verdict
- Trash — wet-strength additives make it dissolve far slower than toilet paper
