What Can and Cannot Go Down Your Drains

10 Things You Should Never Flush Into Your Septic System

Many homeowners accidentally damage their septic systems without realizing it. Your septic tank depends on healthy bacteria to break down waste, and flushing the wrong materials can destroy that balance.

At Duck’s Septic, Pumping & Install, we regularly help Arizona homeowners repair septic issues caused by improper flushing habits.

Here are 10 things you should never put into your septic system.

1. “Flushable” Wipes

Despite the label, flushable wipes do not break down like toilet paper. They commonly clog septic lines and contribute to expensive backups.

2. Grease and Cooking Oil

Grease hardens inside pipes and septic tanks, reducing flow and increasing the risk of blockages.

3. Feminine Hygiene Products

Tampons and sanitary products expand and do not decompose properly inside septic systems.

4. Paper Towels

Paper towels are much thicker than toilet paper and can quickly overload your septic tank.

5. Harsh Cleaning Chemicals

Bleach, antibacterial cleaners, and chemical drain cleaners can kill the beneficial bacteria your septic system needs.

6. Coffee Grounds

Coffee grounds accumulate inside septic tanks and do not break down efficiently.

7. Cat Litter

Cat litter can cause severe clogs and may contain harmful parasites.

8. Medications

Prescription drugs can contaminate groundwater and negatively affect septic bacteria.

9. Paint and Solvents

These hazardous chemicals should never enter your septic system.

10. Excessive Food Waste

Garbage disposals add significant strain to septic systems by increasing solid waste buildup.
