Posted by Melbourne Blocked Drains Plumbers on 29 Mar 2026

The toilet is a ubiquitous household fixture that we all use daily. It’s easy to take its convenience as something we take for granted, but it’s important to remember that it’s not a garbage can. There are some things that shouldn’t be flushed down the drain since they can cause blockage inside the sewer or damage the sewer pipe.

Key Takeaways

  • Do not flush certain things into the toilet because they can cause blockages in the drain or harm to pipes in the sewer.
  • Seven household items you shouldn’t to flush down the toilet are:
    • Baby wipes
    • Condoms
    • Oil and cooking fat
    • Products for feminine hygiene (tampons and sanitary pads)
    • Medications
    • 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 comes at an unimaginable cost to you.
  • Melbourne Blocked Drains Plumbers offers unblocking blocked drains and drain clearing services CCTV drain inspection and pipe relining.

These are the seven items in your home you should never flush down the toilet.

1. Baby wipes

Baby wipes may seem convenient however, they do not disintegrate like toilet paper and can clog your plumbing system. Throw them away in the trash instead.

2. Condoms

Dissolving condoms in the toilet can lead to blockages in the plumbing of your home as well as wastewater treatment plants.

3. The cooking grease and oil

Grease and oil should be disposed of in a container before throwing it away in the trash, because they’ll get hard and cause obstructions in your drains or pipes.

4. Feminine hygiene products

Tampons and sanitary pad are usually marketed as "flushable, " but flushing them will only lead to problems later when they mix with other things to cause a terrible clog.

5. Medicines

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

6. Dental floss

Dental floss is crafted to be sturdy that means it will not be able to break when wet, which can lead to possible blockages in your pipes.

7. Paper towels

In contrast to toilet paper, papers have a stronger weave that 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 eventually lead to blocked drains as well as damaged pipes in your plumbing system which comes at an unforetold cost to the homeowner. Be mindful of what you send down the toilet.
