A wastewater drain assembly is provided that includes a selectively openable drain stopper. The wastewater drain assembly is interconnected to a fluid basin wherein a flange, which is interconnected to wastewater plumbing, is situated within the sink. The flange receives an insert that has a portion that conceals the flange.

A bathtub drain stopper includes an open-close mechanism having threaded upper and lower ends, a cap, a seal, and means for anchoring the open-close mechanism in a drain pipe, where the length can be adjusted and fixed with a lock nut. A threaded anchor is provided for a tub shoe having a crossbar with a threaded opening. An anchor having prongs is provided for a tub shoe having a crossbar with no opening. A wheel-shaped anchor having an O-ring about its perimeter is provided for a drain that does not have a crossbar.

Drain valve assembly for a basin includes a drain having a sidewall, which defines a first opening in fluid communication with the basin and with a first portion of the drain. Sidewall includes wall formation positioned within the drain which extends across the first opening separating the first portion of the drain from a second portion of the drain. First portion of the wall formation extends in a first direction away from the basin and defines an outlet opening which extends through the first portion. Plug member is aligned with the outlet opening and movable from a first position with the plug member abutting the first portion and closing the outlet opening and to a second position wherein the plug member is positioned spaced apart from first portion placing the outlet opening in an open position providing fluid communication between the first portion and the second portion of the drain.

A stopper cartridge for a drain system of a fluid basin, components thereof and related methods are provided. The stopper cartridge includes a stopper head and a strainer to strain fluid passing through the drain system when the stopper head is in a drain position. The stopper head and the strainer may be selectively removable from the drain system by manipulating the stopper head relative to the drain system or a component installed in the drain system.

A drain control assembly having a pop-up stopper controlled by a cam actuating mechanism allowing the stopper to alternately seal and unseat from the drain opening by pressing down on the stopper. Actuator guide rings extending from vertical fins and tabs are used to align and removably secure the actuator in position within the drain pipe. The stopper seal seats against the sink housing the drain providing a water tight seal. The assembly has a removable catch screen to retain items fallen into the drain. The stopper and actuator assembly can be dislodged and the entire assembly removed and items in the catch screen can be retrieved or the actuator removed for cleaning. The assembly can then be reinstalled by simply inserting it down into the drain.

A drain strainer is provided that includes a flange and a basket. The flange transitions to a central cavity. The basket defines the central cavity and includes perforations that are sized to enable liquid to drain through the basket while debris is collected in the basket. The basket has a flexibility of a sufficient value such that the basket may be stretched in a downstream direction to a predetermine value and then released to eject the debris from the basket.

The present utility model provides a magnetic suspension drain, comprising a first connecting member and a second connecting member that are connected with each other and adapted to respective connection to a drain opening of a drain device and a drain pipe. The magnetic suspension drain further comprises a magnetic suspension inner core arranged in the first connecting member, and the magnetic suspension inner core comprises a rotary floating rod and a rotary sealing cover. The rotary floating rod is provided with a first magnet, and a repulsive second magnet is provided inside the first connecting member. The magnetic suspension inner core is configured as follows: in a sealed state, the rotary floating rod drives the rotary sealing cover to maintain sealing with a drain end of the first connecting member under the action of a repulsive force of the first magnet and the second magnet; and in a draining state, the rotary sealing cover is disengaged from the sealing with the drain end of the first connecting member under the action of water pressure and rotates along with the water flow to promote drainage. The present utility model provides a magnetic suspension inner core that utilizes magnetism to realize automatic sealing and drainage, and rotates along with the water flow during drainage to promote drainage through the rotary floating rod and the rotary sealing cover that are integrated into one whole piece.

A drain assembly includes a drain body and an expanding assembly. The drain body includes a first flange and a second flange that each extend away from an inner surface of the drain body towards a center of the drain body. The expanding assembly is positionable within the drain body between the first flange and the second flange. The expanding assembly includes a lattice body. The lattice body can be adjusted relative to the drain body such that the expanding assembly applies an axial force to the first flange and the second flange.
