7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Adelaide Blocked Drains Plumber on 24 Oct 2025

Toilets are a common household fixture that we all are using every day. It’s easy to take its convenience for granted, but it’s essential to keep in mind that it’s not a garbage can. Certain things should never go down the toilet because they could cause blockage in the drain or damage in sewer lines.

Key Takeaways

  • Don’t flush certain items into the toilet because they could block the drain, or cause damages to the pipes.
  • Seven household items that you shouldn’t flush down the toilet include:
    • Baby wipes
    • Condoms
    • Oil and cooking fat
    • Products for female hygiene (tampons and pads for sanitary use)
    • Medications
    • Dental floss
    • Paper towels
  • Cleaning any of these items can result in blockages in drains or damaged pipelines within your home’s plumbing system. This can result in an unimaginable cost to you.
  • Adelaide Blocked Drains Plumber offers unblocking blocked drains drainage clearing, CCTV drain inspection, and pipe relining.

These are the seven items in your home should not be flushed in the toilet.

1. Baby wipes

Baby wipes are a convenient option however, they do not dissolve like toilet paper and can clog water lines. Put them in the garbage instead.

2. Condoms

Dissolving condoms in the toilet could cause blockages in the plumbing of your home as well as the wastewater treatment plant.

3. Cooking grease and oil

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

4. Female hygiene products

Tampons and sanitary pads are typically advertised as "flushable, " but flushing them could cause troubles later on if they mix with other things and cause a obstruction.

5. Medications

It is not recommended to flush medications into the toilet as they can contaminate our water sources.

6. Dental floss

Dental floss is designed to be tough and durable, meaning it won’t break apart when wet, which can lead to the possibility of blockages to your pipes.

7. Paper towels

In contrast to toilet paper, Paper towels have a thicker weave, which means they are less likely to deteriorate quickly once wet, meaning they can quickly cause blockages.

If you flush any of the seven items will eventually 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 put down the drain.
