Your toilet is designed to handle only human waste and toilet paper—nothing more, nothing less. Flushing anything else can lead to clogged pipes, sewer backups, and costly plumbing repairs. Yet, many people unknowingly misuse their toilets as trash cans.

In this blog, we’ll cover 10 items you should never flush down the toilet to protect your plumbing and the environment.

—

1. Wet Wipes (Even “Flushable” Ones)

Wet wipes are a major cause of plumbing problems. Even those labeled “flushable” don’t break down like toilet paper, leading to clogs and fatbergs in sewer systems.

Better Option: Toss all wipes in the trash.

—

2. Paper Towels and Tissues

Paper towels and tissues are thicker than toilet paper and don’t disintegrate quickly. Flushing them can block pipes and create plumbing headaches.

Quick Tip: Use toilet paper exclusively in the bathroom.

—

3. Feminine Hygiene Products

Tampons, pads, and liners are not designed to break down in water. They expand when wet and can easily cause blockages in your plumbing system.

Disposal Tip: Wrap them in tissue and dispose of them in the trash.

—

4. Cotton Balls and Q-Tips

While small, cotton balls, swabs, and similar items don’t dissolve in water. Over time, they can accumulate in your pipes and cause stubborn clogs.

Pro Tip: Use a trash bin for all personal care items.

—

5. Dental Floss

Dental floss may seem harmless, but it’s non-biodegradable and can tangle with other debris to form blockages.

Solution: Throw used floss in the trash to avoid plumbing problems.

—

6. Grease, Oil, and Fat

Pouring grease or oil into the toilet can harden inside your pipes, creating clogs that are difficult to remove. It also contributes to fatbergs in sewer systems.

Disposal Tip: Let grease cool and solidify, then scrape it into a container and throw it away.

—

7. Medications

Flushing expired or unused medications pollutes water systems and harms aquatic life. Most wastewater treatment plants can’t filter out these substances.

Eco-Friendly Option: Use a pharmacy’s medication disposal program.

—

8. Hair

Hair clumps together and can quickly form blockages in your plumbing system. Whether it’s a few strands or a large wad, always toss hair in the trash.

—

9. Diapers

It might seem obvious, but diapers are a common cause of toilet clogs. They’re too large and absorbent to pass through pipes.

Disposal Reminder: Wrap diapers securely and dispose of them in a trash bin.

—

10. Food Scraps

Toilets aren’t garbage disposals. Food scraps can attract pests and cause buildup in your plumbing, especially if they contain grease or oils.

Tip: Compost or throw food waste in the trash.

Why Flushing the Wrong Items is a Big Problem

Clogged Pipes: Non-flushable items block your plumbing and may require professional repairs.

Sewer Backups: When clogs occur in the main sewer line, it can lead to wastewater backing up into your home.

Environmental Damage: Many flushed items end up in rivers, oceans, and waterways, harming wildlife and ecosystems.
