Abstract
A toilet plunger has a hollow tube with a rotatable handle at one end and a bell shaped plunger member with a top opening secured at the other end. A helix shaped stem is connected to the handle and extends the length of the tube. The stem extends through the upper section of a declogger member which is positioned adjacent to the stem. Rotational turning of the handle causes the declogger member to travel down the stem, through the top opening and out the plunger member, to assist in unclogging stopped-up toilet drainage lines and the like. Reversing the rotation of the handle causes the declogging member to be withdrawn back into the tube, but not before it is scrapped clean by a wiper member protruding from the top opening, into the interior space of the plunger member.
