Here are seven household items you shouldn’t flush down the toilet.

1. Baby wipes

Baby wipes might seem useful but they don’t disintegrate like toilet paper, and they can block the plumbing in your home. Put them in the garbage instead.

2. Condoms

Toilet paper that contains condoms could cause blockages in both your home’s plumbing and the wastewater treatment plant.

3. Cooking grease and oil

Oil and grease must be put in a container and thrown away in the garbage, since they will harden and cause blockages in your drains and pipes.

4. Products for feminine hygiene

Tampons and sanitary pad are usually marketed in the form of "flushable, " but flushing them is not likely to cause issues later on when they are combined with other items to cause a terrible blockage.

5. Medications

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

6. Dental floss

Dental floss is crafted to be durable so it won’t be able to break in water, leading to possible blockages in your pipes.

7. Paper towels

As opposed to toilet paper paper towels have a thicker weave which helps them to deteriorate rapidly once they are wet, which means they won’t quickly cause blockages.
