GT Water Products Master Plunger Toilet Plunger with Holder 18-1/2 in. L X 3 in. D

Clogs are cleared with plungers through the process of water displacement. The more water pushed towards the clog per plunge determines the ability of the plunger. Standard-design rubber cup plungers displace about 2 to 4 cups of water per plunge. The bellows design Master Plunger displaces between 8 to 10 cups per plunge, depending on the model.
