What Not to Flush: Protecting Your Septic System This Winter

February in the midwest means cold temps, frozen ground, and a septic system that’s already working hard. The last thing you want this time of year is a backup caused by something that should never have been flushed in the first place.

If you’re on a septic system, here’s a simple rule: Only flush toilet paper and human waste. Everything else can cause problems.

1. “Flushable” Wipes

Even wipes labeled flushable do not break down like toilet paper. They can clog pipes, collect in your tank, and lead to costly backups—especially in winter when cold temperatures slow everything down.

2. Paper Towels and Tissues

These are thicker than toilet paper and don’t dissolve properly. Over time, they build up in your tank and create blockages.

3. Feminine Hygiene Products

Tampons and pads are designed to absorb and expand. In a septic system, that means trouble. They can clog pipes and reduce your tank’s efficiency.

4. Grease, Oils, and Fats

While not typically flushed down a toilet, these often end up in drains. In cold February weather, grease hardens quickly and can block pipes before it even reaches your tank.

5. Diapers and Cotton Products

Diapers, cotton balls, and swabs do not break down in a septic system. They stay in the tank and increase the risk of overflow.

6. Harsh Chemicals

Bleach, antibacterial cleaners, and drain cleaners can kill the beneficial bacteria your septic tank relies on to break down waste. Without those bacteria, your system cannot function properly.

Why Winter Makes It Worse

Frozen soil and heavy ground moisture in Kansas and Missouri can already slow drainage in your leach field. Adding clogs or buildup to the mix increases the chance of backups inside your home—never fun, especially in February.

Keep It Simple

To avoid emergency service calls this winter:

• Flush only toilet paper and human waste
