Flushing the wrong things can cause plumbing disasters. Some items clog pipes, harm the environment, or damage sewer systems. Even if they seem harmless, these items can lead to costly repairs and serious blockages. Toilets are designed to handle only human waste and toilet paper. Flushing anything else increases the risk of plumbing issues. Avoid these 12 common household items to keep your plumbing safe and functioning properly.
Baby Wipes and Wet Wipes
Baby wipes may say “flushable,” but they don’t break down like toilet paper. These wipes clog pipes and cause sewer backups. Unlike toilet paper, they stay intact in water, which means they collect and form large blockages. Many cities deal with massive sewer blockages from flushed wipes, sometimes called “fatbergs.” These can damage municipal systems and require expensive repairs. Even if a wipe makes it through your pipes, it still contributes to pollution. Always throw them in the trash instead of flushing them to prevent these problems.
Paper Towels and Napkins
Paper towels absorb water instead of breaking down. They are thicker than toilet paper, making them prone to clogging pipes. Even a single paper towel can start a blockage, leading to slow drainage or backups. These products are designed to be strong and absorbent, which means they do not dissolve easily in water. If flushed regularly, they can accumulate in pipes and cause severe plumbing issues. Instead of flushing, toss them in the trash or compost bin if they are made from biodegradable materials. This simple step can save you from expensive plumbing repairs.
Cotton Swabs and Cotton Balls
Cotton products don’t dissolve in water. Cotton swabs and balls expand when wet, making blockages worse. They also get tangled in pipes and lead to slow drains. Unlike toilet paper, which breaks down quickly, cotton fibers remain intact and form clusters that cause serious plumbing problems. When flushed, cotton products can also contribute to larger sewer blockages and damage wastewater treatment systems. To avoid costly repairs and potential water contamination, always throw cotton swabs and balls in the trash instead of flushing them.
Feminine Hygiene Products
Tampons and pads absorb liquid and expand. This makes them one of the worst things to flush. They block pipes, damage sewer systems, and cause plumbing backups. Because they are designed to retain moisture, they do not break down in water. Flushed feminine hygiene products often lead to expensive plumbing repairs and contribute to environmental pollution. Many wastewater treatment facilities struggle to filter out these materials, leading to blockages in public sewer lines. Always wrap them in toilet paper and dispose of them in the trash to keep your plumbing and the environment safe.
Dental Floss
Dental floss is small, but it causes big problems in pipes. It tangles with other debris, forming large clogs. Floss doesn’t break down and can create long-lasting blockages. Even though it seems harmless, its thin, stringy nature makes it a major contributor to plumbing issues. When flushed, dental floss can wrap around other debris and form large, stubborn clogs in household pipes and municipal sewer systems. Over time, these clogs can lead to serious backups and expensive repairs. Always throw floss in the trash to prevent plumbing issues and protect your drainage system.

Hair
Hair binds with grease and other debris to form solid clumps. These clumps grow over time and clog drains. Hair also sticks to pipe walls, making future blockages worse. When flushed, hair does not dissolve or break down; instead, it collects in pipes and forms knots that trap other debris. This leads to reduced water flow and slow drainage, eventually resulting in full blockages. Hair is one of the most common causes of drain clogs, and once it accumulates, removing it can be difficult. Instead of flushing, throw hair in the trash or compost it if possible.
Medications
Flushing medication contaminates water supplies and harms aquatic life. Wastewater treatment plants can’t remove all drug residues. This means flushed medicine can end up in rivers and oceans, where it affects fish and other wildlife. Certain drugs can disrupt ecosystems and even enter drinking water sources. Instead of flushing, take unused medication to a pharmacy or a drug disposal site. Many communities have take-back programs where expired or unwanted medications can be safely disposed of. Proper disposal prevents contamination and keeps waterways safe.
Cooking Grease and Oil
Liquid grease may seem harmless, but it solidifies in pipes. Over time, it creates thick blockages that trap other debris. These grease buildups cause sewer overflows and costly repairs. Even if grease is in liquid form when poured down the toilet, it will cool and harden inside the pipes, creating a sticky, stubborn blockage. The best way to dispose of cooking grease is to let it cool and harden in a container before throwing it in the trash. You can also reuse or recycle cooking oil in some areas. Never pour grease down any drain, including the toilet.
Cigarette Butts
Cigarette butts are made of plastic fibers that don’t break down. They contain toxic chemicals that pollute water supplies. Flushing them leads to environmental damage and clogs sewer systems. These butts can release harmful substances into the water, affecting aquatic life. Because cigarette filters are not biodegradable, they remain intact for years, contributing to pollution. Instead of flushing, always dispose of cigarette butts in the trash. Consider using designated cigarette disposal containers to keep these pollutants out of waterways and prevent plumbing issues.
Band-Aids and Adhesive Products
Band-Aids contain plastic and adhesives that don’t dissolve in water. They stick to pipes and create blockages. Over time, they contribute to sewer clogs. Since they are made with non-biodegradable materials, they remain in the plumbing system for a long time, worsening clogs over time. Wastewater treatment plants struggle to filter out these materials, which can end up in the environment. Instead of flushing, always throw used Band-Aids and adhesive products in the trash to prevent plumbing damage and reduce waste buildup.
Cat Litter
Even “flushable” cat litter isn’t safe for toilets. It absorbs water, clumps together, and blocks pipes. Cat waste also contains parasites that survive water treatment. Flushing cat litter can introduce harmful bacteria and parasites, such as Toxoplasma gondii, into water sources. These parasites can pose risks to marine life and even humans. Even if the packaging says the litter is flushable, it is best to dispose of it in the trash. This prevents plumbing problems and protects public water systems from contamination.
Disposable Face Masks and Gloves
Face masks and gloves became common during the pandemic. But they belong in the trash, not the toilet. They don’t break down and can cause major pipe blockages. Disposable masks and gloves are made of synthetic materials that remain intact for a long time. When flushed, they can clog pipes, damage sewage treatment systems, and contribute to environmental pollution. Always dispose of these items in a waste bin to prevent plumbing problems and keep sewer systems running smoothly.
Conclusion
Flushing the wrong items can lead to costly plumbing problems and environmental damage. Toilets are only designed for human waste and toilet paper. Anything else can clog pipes, harm water treatment systems, and contribute to pollution. By keeping these 12 items out of your toilet, you can avoid expensive repairs and protect the environment. Small changes in disposal habits make a big difference in plumbing health. Always use the trash for non-flushable items, and consider eco-friendly alternatives when possible.
