Abstract
A vented toilet plunger that includes a cup and a handle. The cup has a vent valve assembly that extends through a high point of the cup. The vent valve assembly is a check valve that contains a ball that normally allows communication through the check valve. The ball of the check valve is of a weight that is not overcome by air, but is overcome by water, so as to allow communication through the check valve when the cup is first put into the water so as to allow the air trapped in the cup to be vented out, but once the air is vented out, the water fills the cup and moves the ball of the check valve to block communication through the check valve so as not to allow the water to pass therethrough.
