3. cooking grease and oil

Grease and oil must be removed from a container, and then disposed of in the trash, as they’ll harden, causing blockages in your drains or pipes.

4. Products for feminine hygiene

Tampons and sanitary pad are usually advertised to be "flushable, " but flushing them can cause problems later when they are combined with other items to cause a terrible clog.

5. Medicines

Medications should never be flushed through the toilet, as they can be a source of contamination for water sources.

6. Dental floss

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