Posted by Melbourne Blocked Drains Plumber on 13 Dec 2025

The toilet is a ubiquitous fixture in the home that we utilize every day. We tend to think of its convenience as something we take for granted, but it’s important to remember that it’s a toilet, not a garbage can. There are certain items that shouldn’t to be flushed into the drain as they can cause blockage inside the sewer or damage to sewer pipes.

Key Takeaways

  • Avoid flushing certain things down the toilet as they can cause blockages in the drain or damage to sewer pipes.
  • Seven household items you should never flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking oil, as well as cooking grease
    • Products for female hygiene (tampons and pads for sanitary use)
    • Medical Treatment
    • Dental floss
    • Paper towels
  • Cleaning any of these items will ultimately lead to blocked drains or damaged sewer pipelines inside your home’s plumbing system, which will result in an expense that is unimaginable to you.
  • Melbourne Blocked Drains Plumber offers unblocking blocked drains, drain clearing, CCTV drain inspection, and pipe relining services.

There are 7 household things you should never flush into the toilet.

1. Baby wipes

Baby wipes are a convenient option but they don’t dissolve like toilet paper. They can also clog your plumbing system. Throw them away in the trash instead.

2. Condoms

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

3. The cooking grease and oil

Oil and grease must be removed from the container, and then disposed of in the trash, as they’ll get hard and cause obstructions in your drains, or pipes.

4. Produits for female hygiene

Tampons and sanitary pads are typically advertised by their name as "flushable, " but flushing them is not likely to cause trouble later on when they mix with other things and cause a clog.

5. Medications

Medications should never be flushed down the toilet because they can be a source of contamination for water sources.

6. Dental floss

Dental floss is designed to be strong so it won’t split in water, causing the possibility of clogging 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 they’re wet. They can easily cause blockages.

In conclusion, flushing any of these items will ultimately lead to blocked drains or damaged pipelines within your home’s plumbing system which will incur a huge expense to the homeowner. Be mindful of what you send down the toilet.
