Plumbing Myths Busted: What Really Happens When You Flush These Items? Jan 07, 2026

If you've ever wondered what happens when you flush certain items down the toilet, you're not alone. Many of us have fallen victim to common plumbing myths that can lead to costly consequences. Today, we're debunking some of these myths and explaining what really happens when you flush these common household items.

Let's start by addressing a widespread myth: "Anything labeled as 'flushable' is safe for my plumbing." While it may be tempting to trust the label, the reality is more complex. Items labeled as flushable, such as certain wipes, don't break down like toilet paper. This can lead to clogs in your pipes or even cause havoc within municipal sewer systems. It's best to dispose of these items in the trash to avoid potential plumbing disasters.

Another common misconception is that cotton balls and paper towels can be flushed safely. Despite their fibrous texture, cotton balls and paper towels are notorious for absorbing water and not breaking down quickly. This characteristic can make them a prime suspect for toilet clogs and other plumbing issues. Flushing these items may seem harmless at first, but over time, they can merge with other residue, causing blockages that could require professional intervention from experts like The Drain Force.

You might also believe that dental floss is harmless because of its size, but it too can contribute to significant plumbing problems. Dental floss is made of non-biodegradable nylon or Teflon, which can form a net that traps other debris. When flushed, it can combine with other waste materials to create stubborn blockages. To keep your pipes clear and flowing, always throw dental floss in the garbage.

Grease might seem like a surprising addition to the list of non-flushable items, but pouring cooking grease down the toilet is another myth to be cautious of. Once it enters your pipes, grease can harden and create sticky, impenetrable residues that lead to major clogs. It’s advisable to dispose of grease in a heat-safe container and throw it away once it has cooled down. This simple step can safeguard your plumbing system from costly repairs.

Moreover, those leftover medications sitting in your medicine cabinet should never find their way down the toilet. Flushing medications do not necessarily cause immediate clogs, but it poses a significant environmental threat. Pharmaceuticals can contaminate the water supply, harming aquatic life and potentially making their way back into our drinking water. Many communities offer safe disposal options for old medications, such as take-back programs or designated drop-off locations, ensuring both your plumbing and environment remain safe.

In conclusion, maintaining a healthy plumbing system and protecting the environment requires mindful habits and an understanding of what should and shouldn't be flushed down the toilet. By debunking these common myths and adopting more responsible disposal practices, you can avoid unnecessary plumbing issues and ensure that your plumbing system remains efficient.
