A stopper of a bathroom sink or tub includes a shank removably connected to a base part which is connected to the sink or tub and has a drain hole. A cap is connected to the shank and has a flange that extends radially from the cap. A connection portion is formed on the underside of the flange. A seal part is connected to the connection portion and includes a support ring and a collar. The support ring has at least one hook member formed in the inner periphery thereof so as to be connected to the connection portion of the cap. A positioning portion extends from radially from the support ring. The collar is a rubber collar and has a groove in the inner periphery thereof. The positioning portion of the support ring is engaged with the groove to prevent the collar from deformation and generating noise.

A drain for sanitary fixtures such as sinks, tubs or the like is described. The drain is provided with an automatic overflow mechanism, of the magnetic type, configured to be automatically activated when the water level in the sanitary fixture reaches the maximum level allowed. The overflow mechanism comprises a first magnetic element arranged on a stem of the plug, and a second magnetic element integral with the head of the plug and in-between the base and the first magnetic element. In the raised position of the plug, corresponding to the raised position of the head, the first magnetic element and the second magnetic element are magnetically coupled. When a threshold value of the water pressure acting on the head is exceeded, the first magnetic element and the second magnetic element are automatically uncoupled, causing the descent of the head towards the lowered position, corresponding to the opening of the mouth of the sanitary fixture initially closed by the plug. The drain preferably further comprises a manual lifting mechanism to lift the plug, configured to bring back the plug to the raised closed position following activation. Preferably, also the lifting mechanism is magnetic.

An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. A head of the drain closure assembly is fastened to a top end of a stem, wherein a bottom end of the stem is insertable in a drain shoe; and a gasket is fastened around an outer cylinder of the stem below the head. The gasket comprises an upper outer portion and a lower outer portion that each meet at a line that defines a hinge at which the gasket is able to bend, wherein the lower outer portion features a sloped surface from a bottom edge of a rim of the gasket to the line at a top of the lower outer portion, wherein the upper outer portion has a right circular cylinder shape.

The present disclosure is generally directed towards a clean drain system. The clean drain system includes drain stopper system, a seal, and a flange. The seal is coupled to the flange. The drain stopper system is positioned through the seal. The drain stopper system further includes a drain cover, a drain housing, and a basket. The drain cover along a vertical axis to allow or prevent the flow of water through the tailpipe. The basket includes a plurality of openings. The basket is configured to catch debris as it flows downward through the drain to prevent the drain from clogging. The clean drain system further includes an overflow cover, an overflow tube, and a collar. The collar is positioned around the drain housing. The overflow cover is coupled to the overflow tube. The collar is coupled to another end of the overflow tube.

A stopper of a bathroom sink or tub includes a shank removably connected to a base part which is connected to the sink or tub and has a drain hole. A cap is connected to the shank and has a flange that extends radially from the cap. A connection portion is formed on the underside of the flange. A seal part is connected to the connection portion and includes a support ring and a collar. The support ring has at least one hook member formed in the inner periphery thereof so as to be connected to the connection portion of the cap. A positioning portion extends from radially from the support ring. The collar is a rubber collar and has a groove in the inner periphery thereof. The positioning portion of the support ring is engaged with the groove to prevent the collar from deformation and generating noise.

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 clicker drain assembly includes a unitary main drain body. The clicker drain assembly further includes a drain stopper assembly, a clicker drain seal, an actuating assembly, and a drain trim ring. The drain trim ring is configured to couple to the main drain body and receive the clicker drain seal and the actuating assembly. The stopper assembly is configured to couple to the actuating assembly and actuate the actuating assembly when pressed by a user.

A system is provided. The system may include one or more of a tub, a platform, and a lift, coupled to a bottom surface of the platform. The tub includes a top surface, a bottom surface, and a concave well between the top and bottom surfaces. The platform includes water openings extending through a thickness of the platform. The lift is disposed within the tub and is configured to raise and lower the platform within the well.

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.
