Abstract: An automatic leak-proof water inlet device for a water tank, including an inner cylinder, an outer cylinder set, a floating casing and an assist floating set; wherein the outer cylinder set is consisted of an outer cylinder, a cover, a first connecting rod, a second connecting rod, an adjusting rod, an interlocking rod, an insert, a water stopper, a first spring and a second spring; the assist floating set includes a supporting seat and a float; by the above structure, it could stop water leakage of water tank automatically and close water inlet in time, to thereby avoid the waste of water resources.

Abstract: A universal kit for installing a flush lever (22) on a toilet water tank wall (12A), and a toilet with the kit components installed therein, whereby the same components can be used to quickly and efficiently install the handle on the front face, side face, or angled portion of the toilet tank. The kit comprises a fixture (66) for mounting a flush rod actuation handle (20) on a tank wall, whereby the handle can be rotated about an axis (58, 60) extending perpendicularly from the wall into the tank. A flush rod (34) is angulated in three dimensions and has opposite end portions (36, 38), having the same shape, such that either end portion is selectively securable in the mounting fixture (66) for corotation with the handle.

Abstract: An overflow assembly employs an overflow elbow having an externally threaded cylindrical fitting that extends through the tub overflow opening. An internally threaded retainer nut with integrally molded test cap is threadably engaged over the overflow elbow cylindrical fitting to compress gaskets against both the inside and outside surfaces of the tub. A test cap is integrally molded with the retainer nut and joined to the retainer nut by a thin, breakable connection. An undercut lip on the test cap facilitates use of a prying tool to break the thin connection and remove the test cap after testing of the drain plumbing. A trim cap snaps over the retainer nut to provide a finished appearance to the installed overflow assembly.

Abstract: A universal multi-path control valve system includes at least two sets of outlets controlled by a single on/off operator. A compact design allows the control valve system to save space in the compact areas where plumbing fixtures are typically installed. The control valve system is constructed entirely of molded plastic components. Fittings supplied with the control valve system allow for customized installation according to the needs of the installer. Appliances may be easily added or removed using threaded connections on the valve and fittings supplied as part of the control valve system.
