The drain cleaner includes a stopper head having a seal sized to engage the drain inlet and an inlet passage extending from an inlet port formed in a top surface of the stopper head to an outlet port formed in a bottom surface of the stopper head. A stopper guide has a proximal end coupled to the stopper head bottom surface and a distal end, the stopper guide distal end including a tail piece adapted to operatively engage the actuating arm of the pop-up assembly.
