A drain floor, including a drain base, a drain body including a cavity, a drain cup, a supporting frame; and a reset member. The drain cup includes a cup body, a stem, and a base. The cup body includes a through hole, and two ends of the stem are connected to the cup body and the base, respectively. The cup body is disposed in the cavity and the base is disposed out of the cavity. The space between the drain body and the drain cup forms an annular channel, and the annular channel communicates with the through hole. The annular channel includes a water inlet and a water outlet. The reset member is connected to the drain cup and is movable with respect to the drain cup to open and close the water outlet. The supporting frame connects the drain body and the reset member.

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.

A drainage system for engaging and removing accumulating drainage water with a sump pump liner, a sump pump disposed within the liner, and at least one contiguous void with an inner volume in fluidic communication with an inner volume of the liner. The void can comprise a low pressure void compartment disposed distal to the bottom of the liner, or the void can comprise a water harvesting arm with a proximal end retained by the main body of the liner and a body portion that projects from the main body. Liner-void apertures can be disposed in the bottom of the main body of the liner, and void-environment apertures can be disposed in a void bottom partition. The main body can have a rectangular cross section with a lateral water harvesting arm projecting from each sidewall.

A concealed embedded component for a waterway system includes a lower main body with a cool water inlet passage, a hot water inlet passage, a mixing water passage and at least an outlet passage; an embedded box including a box body and a fixing frame covering the box body; a water testing element with the bottom surface disposed with a first passage and a second passage. The lower main body is disposed in the box body, the water testing element is disposed in the box body, the water testing element covers the lower main body to constitute the outlet passage, and the mixing water passage is connected to the cool water inlet passage or the hot water inlet passage. Since the lower main body is disposed in the box body and is separated from concrete, it is convenient to disassemble the concealed embedded component for maintenance.
