7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Sydney Blocked Drains Plumber on 4 Feb 2026

Toilets are a common fixture in our homes that we utilize every day. It’s easy to take the convenience of it for granted, however it’s essential to keep in mind that it’s a toilet, not a garbage can. Certain things should not go down the toilet as they can cause blockage inside the sewer or damage in sewer lines.

Key Takeaways

  • Be careful not to flush certain items down the toilet as they could cause blockages in the drain or harm to pipes in the sewer.
  • Seven household items that you should never flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking grease
    • Feminine hygiene products (tampons and sanitary pads)
    • Medications
    • Dental floss
    • Paper towels
  • Doing this could result in blocked drains or damaged sewer pipelines inside your home’s plumbing system which comes at an unimaginable cost to you.
  • Sydney Blocked Drains Plumber offers unblocking blocked drains and drain clearing services, CCTV drain inspection, and pipe relining services.

These are the seven items in your home that you shouldn’t flush into the toilet.

1. Baby wipes

Baby wipes are a convenient option but they don’t disintegrate like toilet paper and could clog water lines. Dispose of them in the trash instead.

2. Condoms

The flushing of condoms in the toilet can result in blockages of both your home’s plumbing and wastewater treatment plants.

3. cooking grease and oil

Oil and grease must be removed from the container, then thrown in the trash, as they will harden and cause blockages in your drains and pipes.

4. Feminine hygiene products

Tampons and sanitary pads are frequently advertised to be "flushable, " but flushing them is not likely to cause problems later when they are combined with other items to form a nasty obstruction.

5. Medicines

Medications should never be flushed through the toilet, as they could contaminate water sources.

6. Dental floss

Dental floss is crafted to be sturdy that means it will not split when wet, which can lead to the possibility of blockages to your pipes.

7. Paper towels

Unlike with toilet paper, papers have a stronger weave that helps them to deteriorate quickly once wet, which means they won’t easily blockage.

If you flush any of the seven items will eventually lead to blocked drains or damaged pipes within the plumbing system of your home, which comes at an unforetold expense to the homeowner. Stay mindful of what you pour down your toilet.
