Sinks have an integral drain overflow protection or a conventional overflow port but not both. Conventional drain assemblies have a body comprising a hollow cylinder having either solid upper body portion or an upper body sidewall portion including an opening. The present invention defines a drain assembly having an upper body sidewall portion including a knock out blank which may be left in place or knocked out for use with either type of sink. A knock-out band can be used in combination with the knock-out drain assembly body to be positioned over the knocked out body hole providing a water tight seal should the user chooses to use the knocked out drain assembly in a sink having a conventional overflow port.

The invention describes a quick install lift rod pop-up sink drain assembly comprising a drain body, a drain plug, a horizontal pivot rod used as a lever for raising and lowering the drain plug, a lock ring which rotatably secures the horizontal pivot rod to the drain body, and a lift rod rotatably connected to the outer free end of the horizontal pivot rod and used to raise or lower the free end of the horizontal pivot rod. A spherical portion of the horizontal pivot rod is rotatably captured inside a free end of a connector which is integral with the drain body and which contains pawls which capture the spherical portion of the rod and allow up and down movement of the rod with respect to the drain body, causing the drain plug to open and close.

The present invention relates to plumbing fixtures, and more particularly to drain stopper assemblies used to control the flow of fluid through a drain opening of a sink or bathtub. More specifically, the present invention is a novel drain stopper device that can be attached or removed from a drain without the use of tools and without requiring a user to access the space underneath the drain. The device is preferably comprised of a drain stopper head portion having a repositionable push button in mechanical communication with a spring, a shaft and a pair of repositionable jaws such that the pair of jaws are repositioned to grip or release a pivot rod when the push button is repositioned between a first and a second position.

An accelerated drain system for a walk-in bathtub with a water outlet in a side wall communicates water to a diverter valve biased to circulate the water in the bathtub and movable selectively to communicate water through a reverse check valve to a drain, the reverse check valve biased closed to prevent water flow and movable selectively to allow water flow to the drain, with a controller configured for moving the diverter valve selectively from the second position to the closed position for subsequent use of the walk-in bathtub. A method of rapid draining of a walk-in bathtub is disclosed.

A valve assembly includes a valve head. A valve stem extends from the valve head and into a drain bore in a housing. A first guidance retainer ring is mounted around the valve stem at a first axial location on the valve stem. A second guidance retainer ring is mounted around the valve stem at a second axial location on the valve stem spaced apart from the first axial location.

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.

A pop-up drain assembly for a sink has drain piping, a stopper in the drain piping, a pivot rod for opening and closing the stopper and tends not to clog because the pivot rod is not within a fluid flow path. In one embodiment the stopper has flow diverter plates that channel fluid flowing through the drain piping away from the pivot rod so that hair, waste and debris does not catch on and accumulate on the pivot rod. In another embodiment the stopper and the pivot rod are engaged through magnetic coupling, and the pivot rod does not protrude into the fluid flow path. The stopper is preferably variable in length for adjustment to fit different distances from the pivot rod to the top of the drain piping.

The present disclosure discloses a drain assembly, has a downpipe and a sealing plug; the upper end opening of the downpipe is provided with a connecting pipe seat by integral molding and the upper end opening of the connecting pipe seat serves as a sewer outlet; the downpipe and the connecting pipe seat internally share a connector that can move upward or downward; the upper end part of the connector is linked with the sealing plug; the pipe wall of the downpipe is integrally provided with a guide seat at the position corresponding to the lower end part of the connector; the guide seat is communicated with interior of the downpipe. Furthermore, the stay wire component is elastically clamped on the downpipe through a wave spring, therefore, the installation speed is increased and the sealing effect of the connection is ensured.

The new product improves upon a standard pop-up drain stopper which is controlled by a horizontal pivot rod as is used in bathroom/lavatory sinks. The stopper has a bell receiving base threaded to match a like threaded male “L” shaped pivot rod allowing the stopper removal or installation to be done without removal of the pivot rod to clear a clogged drain. The invention is installed by inserting the “L” shaped directional rod into receiving port of drain tube then inserting the threaded stopper on to the threaded pivot rod and turning in a clockwise motion until fully seated. To remove, push lever downward to raise stopper to apex and turn in a counter clockwise direction and lifting out of drain opening. This allows cleaning of drain clogs without disassembling the mechanical components located under the sink as is required to remove the typical pop-up stopper.
