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 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 drain arrangement that comprises a housing which has a first channel section with an inlet opening, a second channel section with an outlet opening, and a valve seat situated between the inlet opening and the outlet opening. It also has a valve body which is movable from the valve seat, an actuating unit to move the valve body, and an outflow pipe into which the second channel section opens. A first central axis extends centrally through the first channel section, and an outflow pipe central axis extends centrally through the outflow pipe. The outflow pipe central axis intersects the first central axis or alternatively the outflow pipe central axis is at a distance from the first central axis. The actuating unit has an actuating lever acting on the valve body, and an actuator element for actuating the actuating lever, wherein the actuator element extends laterally alongside the outflow pipe.

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.

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.

The present invention provides a press-type overflow drainage device for water container, comprising a lifting control mechanism; the lifting control mechanism is provided an up and down movement member and a fixed component with a through hole for the movement of the up and down movement member; one end of the connecting steel wire is connected with the up and down movement member, and the other end is connected with the transmission mechanism; the lifting control mechanism provides two upper and lower stop positions; the drainage device also comprises a horizontal button assembly which is provided with a button, and connected with the up and down movement member through a joint member while the corresponding up and down movement member stops in the upper and lower stop positions, and the button has the press-in and stop and pop-up and stop positions at the front and rear of the horizontal position. The present invention can make use of the cooperation of the lifting control mechanism, the horizontal button and the overflow outlet, and the button is located at the overflow outlet and can control the drainage device of the water container, and the operation is convenient and can indicate the drainage/storage mode of the drainage device.
