7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Perth Blocked Drains Plumbing on 13 Dec 2025

Toilets are a typical fixture in our homes that we use daily. It’s easy to take the convenience of it as a given, but it’s important to remember that it’s no garbage can. There are certain items that shouldn’t ever be flushed away down the toilet because they can cause obstruction in the drain or damage the sewer pipe.

Key Takeaways

  • Avoid flushing certain things down the toilet as they can cause blockages in the drain, or cause the damage of sewer lines.
  • Seven household items you should never flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking grease
    • Products for feminine hygiene (tampons and pads for sanitary use)
    • Medical Treatment
    • Dental floss
    • Paper towels
  • The act of flushing any of these items can result in blockages in drains or damaged pipes within your plumbing system, which will result in an unforetold cost to you.
  • Perth Blocked Drains Plumbing offers unblocking blocked drains drainage clearing CCTV drain inspection and pipe relining services.

Here are seven household items should not be flushed down the drain.

1. Baby wipes

Baby wipes can be convenient but they don’t break down like toilet paper, and they can block pipes. Dispose of them in the garbage instead.

2. Condoms

Dissolving condoms in the toilet can lead to blockages in both the plumbing in your home and the wastewater treatment plant.

3. cooking grease and oil

Grease and oil should be disposed of in a container, and then disposed of in the trash, as they can harden and cause blockages in your drains and pipes.

4. Feminine hygiene products

Tampons and sanitary pads are often advertised by their name as "flushable, " but flushing them is not likely to cause problems later when they join with other products to form a nasty blockage.

5. Medicines

It is not recommended to flush medications through the toilet, as they could pollute our water sources.

6. Dental floss

Dental floss is designed to be tough and durable, meaning it won’t split in water, causing possible blockages in your pipes.

7. Paper towels

As opposed to toilet paper paper towels have a thicker weave, which makes them less likely to degrade quickly after being they’re wet. They can easily cause blockages.

In conclusion, flushing any of the seven items will ultimately lead to blocked drains or damaged pipes within your home’s plumbing system which will incur a huge cost to you. Be mindful of the items you pour down your toilet.

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".

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.
