The present invention is directed to a sink assembly that can separate particulate contaminants from a liquid in which they are suspended. The sink assembly includes a master trap and at least a first trap with a riser and valve assembly to collect particulates and prevent overflow from the master trap. The sink assembly provides a simple maintenance and cleaning solution.

Showerhead devices incorporate sensors to control bath fill levels. Showerheads have interchangeable attachments, including bristle attachments. Oral care devices are attachable to standard shower arms. Pump devices allow various lotions and fluids to be used in conjunction with showers. Shower organizing devices provide for ordered storage and access to accessories. Bathtub spouts including sensors and valves to control bathtub filled levels.

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.

An intelligent drainage device includes a power supply unit, a water discharge key, drain assemblies, a motor drive unit and a control unit. The drain assembly, installed to a bathtub drain hole, includes a waterstop member, a stepping motor and a receiving tube. The receiving tube engages fixedly and oppositely the waterstop member and a power transmission shaft of the stepping motor. The control unit receives a start/stop signal from the water discharge key, then transmits the signal to the motor drive unit for controlling the power transmission shaft to drive the corresponding waterstop member to move upward or downward. In this device, with a simple touch at the water discharge key, the control unit would control the motor drive unit to activate the stepping motors so as to have all the drain assemblies at the respective drain holes to discharge simultaneously and rapidly the water inside a bathtub.

A drain arrangement that comprises a drain valve 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. There also is a valve body, an actuating unit by way of which the valve body is movable, and an outflow pipe into which the second channel section opens by way of the outlet opening thereof. 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, and the drain arrangement furthermore comprises an overflow unit, which has a first connecting pipe, an overflow pipe and a second connecting pipe.

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.
