Seven household objects that should not be flushed down the toilet.

1. Baby wipes

Baby wipes might seem useful but they don’t dissolve like toilet paper and can clog the plumbing in your home. Throw them away in the garbage instead.

2. Condoms

Dissolving condoms in the toilet can lead to blockages in both the plumbing in your home and wastewater treatment facilities.

3. Food preparation grease and oil

Oil and grease should be disposed of in a container and thrown away in the trash, as they’ll harden, causing obstructions in your drains, or pipes.

4. Female hygiene products

Tampons and sanitary pads are frequently advertised in the form of "flushable, " but flushing them will only lead to problems later when they join with other products to cause a terrible obstruction.

5. Medicines

The flushing of medications should not occur through the toilet, as they could pollute our water sources.

6. Dental floss

Dental floss is made to be durable that means it will not break apart when wet, which can lead to the possibility of clogging your pipes.

7. Paper towels

As opposed to toilet paper the paper towels have a more dense weave which means they are less likely to deteriorate rapidly once they are they are wet. This means that they will not easily cause blockages.

In conclusion, flushing any of these seven items could result in blocked drains or damaged pipelines within your home’s plumbing system which can result in an unexpected cost to you. Be mindful of the items you send down the toilet.
