Think about it: There are many items that people may flush down their toilets that should not be flushed. The toilet was designed to take away human waste. It was not designed for people to toss their used or unused garbage into the toilet. Your toilet is not a garbage disposal! Flushing garbage can have disastrous effects such as:
Clogged toilets and pipes
Damage to wastewater collection and treatment facilities
Harmful to marine life
Cause toxic environmental issues
So what can you flush? Simply put, the waste that comes from your body -- urine, poop, and toilet paper -- should be the ONLY things that are flushed. Everything else should be disposed of in the garbage. Also, items should not be flushed down sink drains. Here is a list of items that may ultimately clog drains or pipes.
Don't flush down toilets or drains the following:
Any wipe that says "flushable"(and those that are non-flushable): Although the package may state they are flushable, these wipes do not easily break down. Their cloth-like feel can cause clogged drains, clogged pumps, and effectively can increase operation and maintenance costs to wastewater treatment plants.
