This video shows you how to unclog a toilet using a plunger. Usually a toilet clog is caused by too much toilet paper. If the water runs out of the toilet, use towels on the floor to absorb excess water. You should place the plunger down into the toilet at an angle and start pumping. When dealing with a low water clog, you can flush the toilet while pumping to get more water into the toilet. You can use any type of plunger.
