ABSTRACT:
A system for clearing clogged drain pipes comprising a drain pipe section either straight or P-trap, having a closeable side inlet adjacent the upstream end of the pipe, means to connect the side inlet to a source of pressurized water, an anti-backflow device removably insertable in said side inlet, and a hinged flap valve inside the drain pipe hanging downwardly in its open position over the interior juncture of the side inlet and the drain pipe and movable upwardly to its closed position to prevent any upward flow through the drain pipe. This system is useful in all drains to remove obstructions in the drain pipe.
