7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Adelaide Blocked Drains Plumber on 2 Nov 2026

The toilet is a ubiquitous home appliance that we regularly use. It’s easy to take the convenience of it for granted, however it’s crucial to remember that it’s a toilet, not a garbage can. There are some things that should not go down the toilet as they can cause blockage in the drain or damage for sewer drains.

Key Takeaways

  • Avoid flushing certain things into the toilet because they could block the drain or the damage of sewer lines.
  • Seven household items that you shouldn’t flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking oil, as well as cooking grease
    • Products for feminine hygiene (tampons and pads for sanitary use)
    • Medications
    • Dental floss
    • Paper towels
  • Cleaning any of these items will ultimately lead to blockages in drains or damaged pipelines within your home’s plumbing system, which will result in an unimaginable cost to you.
  • Adelaide Blocked Drains Plumber offers unblocking blocked drains Drain clearing, CCTV drain inspection, and pipe relining services.

Seven household objects should not be flushed down the toilet.

1. Baby wipes

Baby wipes may seem convenient however, they do not disintegrate like toilet paper and could clog your plumbing system. You should dispose of them in the garbage instead.

2. Condoms

Flushing condoms down the toilet can result in blockages of both your plumbing system and wastewater treatment facilities.

3. Food preparation grease and oil

Oil and grease must be removed from the container and thrown away in the garbage, since they can harden and cause blockages in your drains and pipes.

4. Products for feminine hygiene

Tampons and sanitary pads are frequently marketed as "flushable, " but flushing them is not likely to cause issues later on when they combine with other items to cause a terrible blockage.

5. Medications

Medicines should not be flushed in the toilet since they could pollute our water sources.

6. Dental floss

Dental floss is created to be strong and durable, meaning it won’t split in water, leading to the possibility of clogging your pipes.

7. Paper towels

In contrast to toilet paper, paper towels have a thicker weave which helps them to deteriorate rapidly once they are wet, meaning they can easily cause blockages.

If you flush any of the seven items could result in blocked drains as well as damaged pipes within the plumbing system of your home, that will result in a significant expense to you. 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.
