What Not to Flush Down Your Toilet Guide

Posted September 3, 2016

Toilets are designed to handle human waste and toilet paper, but many common household items can cause major plumbing issues if flushed. Even products labeled as “flushable” often fail to break down properly, leading to clogs, costly repairs, and environmental harm. To help you avoid these problems, we’ve compiled a list of items you should never flush down the toilet.

Items You Should Never Flush

  1. Disposable Wipes: Baby wipes, cleaning wipes, and even "flushable" wipes often don’t break down in water. They can accumulate in your pipes and sewer lines, causing significant blockages.
  2. Feminine Hygiene Products: Pads, tampons, and other products are designed to absorb moisture, not break apart. When flushed, they can expand and lead to stubborn clogs.
  3. Cotton Balls, Q-Tips, Paper Towels, and Facial Tissue: These items do not disintegrate like toilet paper and can create blockages in your plumbing system.
  4. Prescription Medications: Flushing medications doesn’t clog pipes but introduces harmful chemicals into the water supply, affecting ecosystems and water quality.
  5. Cigarettes: Cigarettes contain harmful chemicals and can clog pipes, as well as pollute water systems.
  6. Dental Floss: This stringy material can wrap around other debris, creating large clogs in pipes and sewer lines.
  7. Grease, Fat, and Oil: When poured down the toilet, these substances can solidify in pipes, leading to blockages and damage to your plumbing system.
  8. Hair: Hair tangles and combines with other debris, forming clogs that are difficult to remove.
  9. Cat Litter: Even “flushable” cat litter can clog pipes and is harmful to septic systems. It can also introduce harmful parasites, like Toxoplasma gondii, into waterways.
  10. Food Waste: While it may seem harmless, food waste can expand in water and contribute to blockages.

Why Flushing Improper Items Is Harmful

Flushing items that shouldn’t go down the toilet can cause serious plumbing problems, such as:

  • Clogged Pipes: Non-biodegradable materials can accumulate in your pipes, leading to backups and damage.
  • Sewer Overflows: Items like wipes and grease can clog municipal sewer systems, causing overflows that affect entire communities.
  • Environmental Pollution: Flushed medications and chemicals can harm aquatic ecosystems and contaminate drinking water supplies.

Tips for Proper Disposal

  • Dispose of wipes, feminine hygiene products, and other non-flushable items in a trash bin.
  • Take unused or expired medications to a pharmacy or local hazardous waste collection site.
  • Recycle grease and cooking oil by collecting it in a sealed container and disposing of it at a recycling center.
  • Compost food waste and organic materials instead of flushing them down the toilet.
