Posted by Perth Blocked Drains Plumber on 12 Jul 2026

Toilets are a common home appliance that we use daily. There’s a tendency to accept the convenience of it for granted, but it’s vital to remember that it’s no garbage can. Certain things shouldn’t go down the toilet since they can cause blockage in the drain or damage to sewer pipes.

Key Takeaways

  • Be careful not to flush certain items in the bathroom because they could block the drain or harm to pipes in the sewer.
  • Seven household items that you shouldn’t to flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking fat
    • Feminine hygiene products (tampons and pads for sanitary use)
    • Medicines
    • Dental floss
    • Paper towels
  • The act of flushing any of these items can lead to blockages in drains or damaged pipelines in your home’s plumbing system which comes at unimaginable expense to you.
  • Perth Blocked Drains Plumber offers unblocking blocked drains, drain clearing CCTV drain inspection and pipe relining services.

Seven household objects that you should never flush in the toilet.

1. Baby wipes

Baby wipes might seem useful however they don’t break down like toilet paper. They can also clog pipes. Throw them away in the garbage instead.

2. Condoms

The flushing of condoms in the toilet can lead to blockages in both your home’s plumbing and wastewater treatment facilities.

3. Cooking grease and oil

Oil and grease should be removed from a container, and then disposed of in the trash, because they can harden and cause obstructions in your drains, or pipes.

4. Products for feminine hygiene

Tampons and sanitary pad are usually marketed to be "flushable, " but flushing them could cause trouble later on when they join with other products to create a nasty blockage.

5. Medications

Medications should never be flushed down the toilet because they could pollute our water sources.

6. Dental floss

Dental floss is created to be strong so it won’t be able to break in water, causing the possibility of blockages to your pipes.

7. Paper towels

Unlike with 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.

The bottom line is that flushing any of these seven items can lead to blocked drains or damaged sewer pipelines within the plumbing system of your home, which will incur a huge cost to you. Be mindful of the items you put down the drain.
