A method and apparatus for monitoring a water level in a basin are disclosed. An automatic refill system includes a level sensor coupled to a refill valve system. The refill valve system has a valve driven by an actuator. The actuator receives a signal from a controller in response to a measured water level. The refill valve system flows water into a basin from a water source until a desired level is reached.

A waste outlet having a top section, with an inlet and an outlet, and a bottom section, with an inlet and an outlet. The top section and the bottom section are both mounted upon a substantially elongate member. A tubular seal element encloses the outlet of the top section and the inlet of the bottom section and one of the top section and the bottom section is connected to the elongate member and the other of the top section and the bottom section is slidably mounted on the rigid elongate member so that it can slide therealong to adjust the distance between the respective sections.

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 drain system for controlling a water level in a bathtub includes a drain exit assembly coupled to an exit drain of the bathtub and configured to receive water exiting the bathtub, a valve fluidly coupled to the drain exit assembly and operably coupled to a motor, and a pressure sensor communicatively coupled to the valve and in fluid communication with the drain exit assembly. The motor is configured to change the operational state of the valve based on a pressure sensed by the pressure sensor to control a water level within the bathtub.

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 press-type overflow drainage device for water container includes a lifting control mechanism provided with an up and down movement member and a fixed component with a through hole for the movement of the up and down movement member. The lifting control mechanism provides two upper and lower stop positions. The drainage device includes 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. The button has the press-in and stop and pop-up and stop positions at the front and rear of the horizontal position. The button is located at the overflow outlet and can control the drainage device of the water container.
