ABSTRACT:
A spring loaded drain cleaning device utilizing both positive and negative pressures to disrupt a clog. The invention is composed of a plastic hollow cylinder ending in an angled base cup having a gasket at its lower extremity, a cap at the top of the cylinder, a reciprocally mounted piston and a rod which permits the user to transmit forces onto the piston, and a biasing spring which acts on the piston. The user depresses the rod, causing the piston to descend down the cylinder resulting in fluidic compression in the drain above the clog, along with compression of the spring. Release of the rod results in a spring biased return of the piston up the cylinder, with an attendant negative fluidic pressure above the clog. The cycle is repeated in rapid succession until the clog clears.
