7 Household Items That Should Never Be Flushed Down the Toilet

Posted by Adelaide Blocked Drains Plumbing on 12 Jul 2026

The toilet is a ubiquitous fixture in our homes that we are using every day. The temptation is to consider its utility as a given, but it’s crucial to remember that it’s not a trash can. There are certain items that should never ever be flushed away down the toilet because they could cause blockage within the drainage system or damage for sewer drains.

Key Takeaways

  • Do not flush certain things in the bathroom because they could cause blockages in the drain, or cause damage to sewer pipes.
  • Seven household items that you shouldn’t flush down the drain are:
    • Baby wipes
    • Condoms
    • Oil and cooking fat
    • Products for female hygiene (tampons and sanitary pads)
    • Meds
    • Dental floss
    • Paper towels
  • The act of flushing any of these items can result in blocked drains or damaged sewer pipelines inside your home’s plumbing system. This can result in unimaginable expense to you.
  • Adelaide Blocked Drains Plumbing offers unblocking blocked drains and drain clearing services, CCTV drain inspection, and pipe relining services.

Seven household objects you shouldn’t flush into the toilet.

1. Baby wipes

Baby wipes may seem convenient however they don’t disintegrate like toilet paper, and they can block pipes. You should dispose of them in the trash instead.

2. Condoms

Toilet paper that contains condoms can cause blockages to both the plumbing in your home and wastewater treatment facilities.

3. The cooking grease and oil

Grease and oil should be disposed of in a container before throwing it away in the trash, as they will harden and cause blockages in your drains and pipes.

4. Female hygiene products

Tampons and sanitary pad are usually marketed by their name as "flushable, " but flushing them will only lead to issues later on when they join with other products to cause a terrible obstruction.

5. Medications

Medicines should not be flushed in the toilet since they could contaminate water sources.

6. Dental floss

Dental floss is crafted to be strong that means it will not break apart in water, causing the possibility of blockages to your pipes.

7. Paper towels

In contrast to toilet paper, paper towels have a thicker weave which helps them to deteriorate rapidly once they are they’re wet. They can quickly cause blockages.

The bottom line is that flushing any of these seven items can lead to blocked drains and damaged pipes in your plumbing system which will incur a huge price to you. Be aware of the things you put down the drain.
