The toilet is a standard household fixture that we all use daily. It’s easy to take the convenience of it for granted, however it’s crucial to remember that it’s no garbage can. There are certain items that should never go down the drain because they can cause obstruction from the pipes or damage to sewer pipes.

Flushing condoms down the toilet could cause blockages in both your plumbing system and wastewater treatment plants.

3. Cooking grease and oil

Oil and grease should be put in a container, and then disposed of in the garbage, since they can harden and cause blockages in your drains or pipes.

4. Female hygiene products

Tampons and sanitary pads are typically marketed to be "flushable, " but flushing them can cause problems later when they join with other products to cause a terrible blockage.

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

7. Paper towels
