  • Patent number: 11927001
    Abstract: A pop up stopper comprising multiple aperture and at least one non-aperture lever rod engagement locations to allow use of the stopper as a replacement with different pre-existing actuating and drain systems when the existing stopper is broken, worn or needs to be replaced for aesthetic reasons. An existing lever rod is selectively positionable to engage with one of the lever rod engagement locations that are disposed at varying heights on the stopper. Most preferably, there are six lever rod engagement locations, four aperture locations and two non-aperture locations. A seal disposed below a cap and around a body of the stopper comprises an enlarged annular ring near its outer edge to provide increased surface area for sealing a drain opening. The body of the stopper has a maximum width measured in cross section of 1.04 inches or less.

  • Patent number: 9593473
    Abstract: A plumbing system includes a tub having a drain fixture lodged within a floor drain opening. The drain fixture comprises a body member beneath the floor and a drain cap member inserted into an exposed open inlet of the body member. The body member has a passageway extending between the open inlet and a downstream open outlet in communication with a sewer. A pipe connected to the body member between the inlet and outlet has one end in communication with the passageway and another end in communication with an overflow opening in the tub above the drain opening to vent the passageway. The drain cap member moves between a first position allowing liquid to flow through the passageway and a second position preventing the flow of liquid through the passageway.

  • Patent number: 8327474
    Abstract: A magnetic drain stopper assembly includes an actuating lever in a drain pipe and is movable to allow fluid flow into the drain pipe in an open position and to prevent fluid flow into the drain pipe in a closed position. A magnet on the drain stopper interacts magnetically with the actuating lever or a sleeve on the actuating lever. The magnetic drain stopper is easily removed by simply pulling it out of the drain pipe. Studs on the drain stopper catch objects that fall into the drain pipe for easy retrieval and further catch residue such as hair for easy cleaning.

  • Patent number: 8037558
    Abstract: A wash basin drain structure includes a tightening assembly, a control rod assembly, a drain pipe, and a plug. A threaded top ring of the fastening assembly relative to a threaded annular seat is screwed reversely to push an anti-leakage washer of the drain pipe upward, so that the threaded top ring and a washer are against the bottom of the wash basin and resilient portions of the resilient ring engages with a non-slip portion of the drain pipe. When a threaded fixing member in a threaded hole of a fixing seat of the control rod assembly is screwed inward, the end of the threaded fixing member will hold against the body of the drain pipe and pull an inner pipe portion of the fixing seat to seal and engage with an insertion hole of the drain pipe. A magnetic end head of a link rod of the control rod assembly is attracted to connect with a magnetic portion of a plug body of the plug to act as a lever. The present invention can be assembled with ease.

  • Patent number: 6154898
    Abstract: A wastewater drain control for fluid compartments has a waste water discharge port in the bottom thereof and in communication with a vertical drain pipe. A valve seat element is in the pipe below the port and has an inclined annular valve seat surface and a center opening. A spherical valve element has a diameter greater than the center opening in the valve seat surface and is adapted to close the center opening to fluid flow when dwelling on the valve seat element above the center opening. A valve stem is rigidly secured by an upper end to the spherical valve element. The lower end extends downwardly through the center opening and terminates in a lower end. This lower end is connected to a linkage assembly which extends through a seal element in the vertical pipe and extends to a remote location accessible in the environment of the fluid compartment.
