ABSTRACT:
A manual device for cleaning clogged drains has a manual pump and an electric suction cup, which is mounted on the pump, and communicates with an outlet of the pump. A piston rod with a piston and controllable seals are arranged on the manual pump and together form a valve. During repeated reciprocal displacement of the piston rod, the pump may be selectively operated in a suction mode, withdrawing particles from the drain by aspiration, or in a pressure mode, blasting particles through the drain, depending on the valve adjustment. The device therefore achieves an effective cleansing of drains from clogged particles, while providing convenient handling for a user.
