The Top Things You Should Never Flush Down the Toilet

Updated: Jul 21, 2023


Flushing items down the toilet seems like a convenient way to get rid of waste, but not everything is meant to go down the drain. While toilets are designed to handle human waste and toilet paper, many other items can cause serious plumbing issues when flushed. Flushing the wrong things down the toilet can lead to clogs, backups, and even damage to your plumbing system. In this blog, we will explore the top things you should never flush down your toilet to maintain a healthy plumbing system and avoid costly repairs.

Infographic of things you should never flush down the toilet including wet wipes, feminine hygiene products, dental floss, paper towels, cotton balls, condoms, hair, medications, grease, cooking oil, and cat litter.

1. Wet Wipes and Baby Wipes

One of the most common culprits of toilet clogs is flushing wet wipes and baby wipes. Despite some products claiming to be "flushable," these wipes do not break down like toilet paper. Instead, they can accumulate in the pipes and cause stubborn clogs. Always dispose of wet wipes and baby wipes in the trash.

2. Feminine Hygiene Products

Tampons, pads, and other feminine hygiene products are not designed to be flushed. These items can quickly expand when exposed to water, leading to blockages in your plumbing system. Wrap them in toilet paper or use special disposal bags and throw them in the trash.


3. Dental Floss

Dental floss is thin and may seem harmless, but it is not biodegradable and can easily wrap around other items in the pipes, creating blockages. Throw dental floss in the trash instead.


4. Paper Towels and Tissues

While toilet paper is designed to break down easily in water, paper towels and tissues are not. Flushing them down the toilet can lead to clogs. Always throw paper towels and tissues in the trash.


5. Cotton Balls and Swabs

Cotton balls and swabs are not biodegradable and can cause blockages in the pipes. Dispose of them in the trash or consider using a compost bin for biodegradable items.


6. Condoms

Condoms are made of latex, which is not biodegradable and can clog pipes. Wrap them in tissue or paper and throw them in the trash.


7. Hair

While a few loose hairs may not seem like a problem, over time, hair can accumulate and create clogs in your plumbing system. Dispose of hair in the trash or compost it if possible.


8. Medications

Flushing unused or expired medications down the toilet can contaminate water sources and harm aquatic life. Follow local guidelines for safe disposal or take them to a medication drop-off location.


9. Grease and Cooking Oil

Pouring grease and cooking oil down the toilet can lead to clogs and sewer backups. Dispose of them in a sealable container and throw them in the trash.


10. Cat Litter

Cat litter is designed to clump when it comes into contact with liquid, making it a poor choice for flushing. It can quickly lead to blockages and cause damage to your plumbing system. Dispose of cat litter in the trash.





Flushing the wrong things down your toilet can cause serious plumbing issues and lead to costly repairs. To maintain a healthy plumbing system, it's essential to only flush human waste and toilet paper. Avoid flushing wet wipes, feminine hygiene products, dental floss, paper towels, cotton balls, condoms, hair, medications, grease, cooking oil, and cat litter down the toilet. Proper disposal of these items in the trash or using compost bins for biodegradable items will help keep your plumbing running smoothly and prevent unnecessary headaches. By being mindful of what you flush down your toilet, you can protect your plumbing system and ensure its efficient operation for years to come.
