7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Perth Blocked Drains Plumbers on 13 Dec 2025

The toilet is a ubiquitous home appliance that we regularly use. There’s a tendency to accept its convenience as a given, but it’s essential to keep in mind that it’s no garbage can. There are some things that should never be flushed down the toilet as they can cause blockage inside the sewer or damage the sewer pipe.

Key Takeaways

  • Don’t flush certain items in the bathroom because they can cause blockages in the drain, or cause harm to pipes in the sewer.
  • Seven household items that you shouldn’t flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking fat
    • Female hygiene products (tampons and sanitary pads)
    • Medicines
    • Dental floss
    • Paper towels
  • The act of flushing any of these items could result in blockages in drains or damaged pipelines in your home’s plumbing system which comes at an unforetold cost to you.
  • Perth Blocked Drains Plumbers offers unblocking blocked drains drainage clearing, CCTV drain inspection, and pipe relining.

There are 7 household things that you should never flush into the toilet.

1. Baby wipes

Baby wipes can be convenient but they don’t break down as easily as toilet paper and could clog pipes. Dispose of them in the garbage instead.

2. Condoms

Toilet paper that contains condoms can result in blockages of both your home’s plumbing and wastewater treatment facilities.

3. cooking grease and oil

Oil and grease should be removed from a container before throwing it away in the trash, because they can harden and cause blockages in your drains and pipes.

4. Products for feminine hygiene

Tampons and sanitary pads are typically marketed as "flushable, " but flushing them will only lead to trouble later on when they join with other products to cause a terrible blockage.

5. Medicines

Medicines should not be flushed in the toilet since they can contaminate our water sources.

6. Dental floss

Dental floss is designed to be tough that means it will not be able to break in water, leading to potential blockages in your pipes.

7. Paper towels

Unlike with toilet paper, the paper towels have a more dense weave which will make them less likely to break down quickly when wet, meaning they can quickly cause blockages.

In the end, flushing any of these seven items can lead to blocked drains as well as damaged pipes within your plumbing system which can result in an unexpected cost to the homeowner. Be mindful of the items you put down the drain.

Item Reason for not Flushing
Baby wipes Do not break down like toilet paper and can clog your plumbing system. Dispose of them in the trash instead.
Condoms Leads to blockages both at home’s plumbing and treatment plants.
Cooking grease and oil Will harden and cause blockages in your drains or pipes.
Feminine hygiene products Combining with other items creates a nasty clog despite being marketed as "flushable".
Medications Can contaminate our water sources.
Dental floss Designed to be strong, leading to potential blockages in pipes.
Paper towels Less likely to deteriorate quickly once wet, easily causing blockages unlike with toilet paper.
