A drain stopper and strainer for a kitchen sink has a cap, a cap seal, an open-close mechanism, a strainer connected to a lower end of the open-close mechanism with an easy-connect mechanism, and an annular seal engaged with the strainer that seals an annular space between the strainer and a drain fitting. The cap seal preferably seals against the strainer. The stopper/strainer can be pushed into and pulled out of the drain fitting without assembly or disassembly. The strainer can be easily disconnected for cleaning and can be easily reconnected afterwards. For a drain fitted with a garbage disposal unit, the strainer has a hub-and-spoke structure for preventing eating and cooking utensils from falling into the garbage disposal unit.

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 tub shoe having a cross-bar with a threaded opening. An anchor having prongs is provided for a tub shoe having a cross-bar with no opening. A wheel-shaped anchor having an O-ring about its perimeter is provided for a drain that does not have a tub shoe.

A push-type drain stopper is usable in a drain pipe that has a pivot rod port surrounded by a stub by sealing a rod that protrudes into the pipe through the stub. The stopper is pressed transversely into engagement with the rod, which is an anchor. The drain pipe has a drain flange that seals around a drain opening in a sink. If the flange becomes worn and unsightly or if one desires to change a color scheme for the sink, a cap that has a diameter greater than the drain flange hides the drain flange from sight. A retrofit kit includes the drain stopper, pivot balls sized to fit different pop-up drain assemblies, a rod that passes through the ball into the drain pipe, and a wing nut fixed to an end of the rod for tightening the rod against a stub cap.

Sinks and drains for sinks permitting the attachment of the drain to the sink such that the drain is substantially disposed below the top surface of the sink basin, and such that there is no discernable separation between the base of the sink basin and the drain when viewed from above the sink. A method of making a sink such that there is no discernable separation between the base of the sink basin and the drain when viewed from above the sink.

A bath or basin waste having a plug in which the upper face of the cap is substantially bellow the upper face of the bottom of the bath or basin to which it is fitted when in the closed position and substantially flush with the upper face of the bottom of the bath or basin when in the open position.

A drain stopper assembly that can be simply pushed into and pulled out of a drain pipe includes an open-close mechanism, a cap, a drain seal, and a means for engaging the open-close mechanism with the drain pipe and preferably also includes a strainer. The means includes a wheel-shaped disc that rests on crossbars in the drain pipe and has an annular seal about its perimeter; a ball-and-spring detent mechanism for attaching the drain stopper to crossbars; and a magnet attached to the open-close mechanism, preferably with a ferrous adapter for the drain pipe. The open-close mechanism is a push mechanism, a lift-and-lock mechanism or a lift-and-turn mechanism.

The embodiments disclosed herein provide an adjustable wash basin drain wherein a fitting angle of the contact surfaces between the wash basin and the drain can be adjusted to achieve a better seal between the wash basin and the drain. The wash basin drain may include a split-type drain flange that includes an upper connector seat, a lower connector seat, and a flange connector. The upper connector seat is configured to snap fit to an upper end of a water discharge hole of the wash basin. The lower connector seat is connected to a water discharge pipe, and may be disposed beyond a bottom end of the wash basin. The flange connector connects the upper connector seat with the lower connector seat.

A sink drain may include a drainage tube, a strainer, an O-shaped sealing pad, a push-type water valve, and a general bolt. The drainage tube has a blocking edge at an upper end thereof, and a thread nut is disposed on the drainage tube. The strainer has a cup-shaped main body, and a thread portion is formed on the outer periphery of a lower section of the main body. The thread nut of the drainage tube is engaged with the thread portion of the strainer to complete the connection between the drainage tube and the strainer. The sealing pad, which is elastically deformable, has a first section and a second section, and the first section having a larger diameter than the second section is located above the second section. The push-type water valve with a second O-ring is downwardly put into a third drainage hole of a sink.

A drain stopper apparatus is disclosed and configured for being installed within a drain hole of a fixture, for preventing any buildup of hair or other materials within an associated drainpipe of the fixture. In at least one embodiment, the apparatus provides a stopper body sized and shaped for being positioned within the drain hole of the fixture, in contact with an inner surface of a basin of the fixture. A stopper tailpiece is engaged with a bottom of the stopper body. A stopper is positioned within the stopper body and configured for selectively moving between one of an open position and a closed position. A drive coupler interconnects a lower end of the stopper tailpiece with an upper end of the drainpipe, the drive coupler providing a drive mechanism positioned and configured for selectively actuating the stopper between the open and closed positions.
