Abstract

Disclosed is a basement sewer drain pump housing that draws fluid from a drain into a housing, where after the fluid is discharged from the housing and out of the basement. The device comprises a pickup tube having a fluid level sensor, which is placed within a sewer main drain or floor drain. The housing comprises an enclosed volume, a suction tube connected to the pickup tube, a suction pump, and a discharge pump. The pump is activated by a switch controlled by the pickup tube fluid sensor, the fluid is drawn into the housing from the drain and discharged through a discharge pipe. The device operates from outlet or battery and serves as a basement drain pump that prevents fluid and sewage backflow during power outages and plumbing blockages. Another modification provides two donuts to prevent the flow of fluid locking both the floor drain and the main sewer drain. Another embodiment show an inflator to stop the flow of fluids.
