    Abstract: The pole plunger includes a main shaft having an upper disc secured to an upper end and a lower disc secured to a lower end. The lower disc has a radius greater than that of the upper disc, allowing the user to select the appropriately sized disc which matches the radius of a drain pipe to be plunged. Additionally, a handle portion may be secured to the main shaft, extending in a direction orthogonal thereto, providing the user with a handle to grip during the plunging process. The handle portion further has a handle disc secured to its free end, with the handle disc having a radius between that of the upper and lower discs, providing the user with a third size disc for plunging of the drain pipe.
