Basically, the only things you should ever flush down a toilet are human waste (urine and feces) and toilet paper. Even though some products such as wipes and baby diapers claim to be flushable, they aren’t.
Besides, what happens to toilet paper when flushed?
When you press the flush button, your wee, poo, toilet paper and water go down a pipe called a sewer. … This might be soapy water from baths and showers, or water left over from washing dishes and clothes. Together, all of these wastes are called “sewage”. The pipes they travel through are called “sewerage pipes”.
