Toilets are a typical fixture in our homes that we utilize every day. The temptation is to consider its utility for granted, but it’s essential to keep in mind that it’s a toilet, not a garbage can. Certain things shouldn’t to be flushed into the drain since they can cause blockage within the drainage system or damage in sewer lines.

Key Takeaways

  • Seven household items that you shouldn’t flush down the drain are:
    • Baby wipes
    • Condoms
    • Cooking grease and oil
    • Products for female hygiene (tampons and sanitary pads)
    • Medications

These are the seven items in your home that you should never flush in the toilet.

Baby wipes might seem useful but they don’t break down like toilet paper and can clog pipes. You should dispose of them in the garbage instead.

2. Condoms

The flushing of condoms in the toilet can lead to blockages in both your home’s plumbing and the wastewater treatment plant.

3. Food preparation grease and oil

Oil and grease should be removed from a container and thrown away in the trash, because they’ll get hard and cause obstructions in your drains, or pipes.

4. Female hygiene products

Tampons and sanitary pads are often marketed to be "flushable, " but flushing them will only lead to troubles later on if they combine with other items and cause a blockage.

5. Medications

The flushing of medications should not occur in the toilet since they can contaminate our water sources.

6. Dental floss

Dental floss is created to be tough and durable, meaning it won’t be able to break in water, causing the possibility of clogging your pipes.

7. Paper towels

As opposed to toilet paper paper towels have a thicker weave that makes them less likely to degrade quickly after being wet, which means they won’t easily blockage.

If you flush one of these seven things will ultimately lead to blocked drains as well as damaged pipelines within the plumbing system of your home, which can result in an unexpected cost to the homeowner. Be mindful of what you send down the toilet.
