A bath waste and overflow drain system of the present disclosure may comprise both drain and overflow assemblies. The drain assembly generally includes a drain elbow, drain gasket, drain spud, drain trim, and drain stopper. The drain trim may possess weep channels that urge stagnated water from a periphery of the drain spud and into the drain. The overflow assembly generally includes an overflow elbow, overflow gasket, retaining nut, and overflow faceplate. The overflow faceplate may have bayonet channels that engage with a protrusion of the overflow elbow so as to accommodate variances in tub design when effecting an installation. The system according to an embodiment may also comprise test plugs of the overflow and drain varieties which are, together, operable to permit pressure-related tests of the system prior to completing an installation. The overflow and drain test plugs are simple to manipulate and install/remove with quick-engaging, complementary locking features.

A drain assembly for connection to a sanitary-appliance, comprising: a drain pipe having a pipe inlet and a pipe outlet and a valve arranged in a valve section of the drain pipe having a sealing face and a valve body, wherein the valve body can be moved away from the sealing face from a closed to an open position by an actuating element. Also included is an overflow pipe, which extends away from the drain tube from a first branch lying upstream of the valve seen in the direction of flow of the water to a second branch lying downstream of the valve seen in the direction of flow and thereby bridges the valve. The valve body is at least partially mounted on an insert element; the drain pipe has an insert receptacle; and the insert element can be inserted into the insert receptacle on the drain pipe.

A monitoring system for monitoring a water level in a plumbing element. The monitoring system has a sensor unit, which includes at least one sensor for detecting a measured value and with the aid of which a water level in a receiving space of the plumbing element may be ascertained. A plumbing element is also provided that comprises a receiving space for accommodating water and at least one water outlet for emptying the water from the receiving space.

An overflow cover interconnection system utilizes an overflow elbow with an upper portion for insertion through an overflow drain hole in a bathtub wall; a nut, ring, or other component that fits on or around the upper portion to secure the overflow elbow in position; and an overflow cap that shields the upper portion and nut, ring, or other component from view of a user of the bathtub. The system is configured for use with bathtubs having varying wall thicknesses, without necessitating any modifications.

A sink having an invisible drainage device, comprising an overflow table (1), an overflow basin (2), an auxiliary water tank (3), and a water retaining component; the overflow basin (2) is embedded within the overflow table (1), and the auxiliary water tank (3) is in communication with the overflow basin (2); the water retaining component comprises a limiting plate (21), a movable water retaining plate (22) and a limiting block (23), the limiting plate (21) being fixedly disposed above a water outlet of the overflow basin (2), and the movable water retaining plate (22) being movably provided at a bottom portion of the limiting plate (21) and being located at a position at which the overflow basin (2) and the auxiliary water tank (3) communicate; the limiting plate (21) is disposed at a lower mouth of the overflow basin (2), and a bottom portion of the auxiliary water tank (3) is provided with a water outlet component. The overflow table (1) and the overflow basin (2) are integrally and seamlessly jointed so as to resolve persistent shortcomings such as dirt hiding, bacterium breeding and cleaning being impossible between traditional basins and tables. Moreover, problems such as dirty corners, odor leakage and cleaning being impossible are completely solved, being convenient and safe for users, while setting the mind at ease and alleviating worry. Meanwhile, the overall aesthetics are greatly improved, the sink being more beautiful and more harmonious.

An overflow device for an appliance such as a bathtub, sink or the like. The overflow device comprises a body which connects the overflow device to the appliance. The body includes a body inlet adapted to be connected to an appliance outlet. The body also includes a body outlet adapted to be connected to a soil stack. A drainage flowpath is defined between the body inlet and the body outlet. In use, the drainage flowpath creates a water seal between the body inlet and body outlet. The overflow device also includes a pipe arrangement in fluid communication with the body, where the pipe arrangement defines an overflow flowpath between the body inlet and the body outlet, such that, in use, at least a portion of the overflow flowpath is beneath the level of the water seal.
