How does plumbing work?

You use it to go number 1 or number 2 (sorry but I'm not gonna write it )then you flush and it goes down to the sewer.

and if your not asking about that I'm sorry and listen to this.

It flushes and it goes down and how that happens is the part in the squarish part uses special equipment and when you pull down the handle it trigger the tubes to shoot put water and the toilet sucks it down.
