Embodiments of the present disclosure generally provide a grey water interface valve liquid level sensor system. The liquid level sensor system may deliver information about the water level and the water movement that occurs in a water reservoir. A control unit may then activate a valve to open so that the water can be removed via vacuum.

The embodiments disclosed herein provide an adjustable wash basin drain wherein a fitting angle of the contact surfaces between the wash basin and the drain can be adjusted to achieve a better seal between the wash basin and the drain. The wash basin drain may include a split-type drain flange that includes an upper connector seat, a lower connector seat, and a flange connector. The upper connector seat is configured to snap fit to an upper end of a water discharge hole of the wash basin. The lower connector seat is connected to a water discharge pipe, and may be disposed beyond a bottom end of the wash basin. The flange connector connects the upper connector seat with the lower connector seat.

The present disclosure provides a system for recovering and reusing graywater generated from at least one graywater source in a building. The system includes a controller configured to control recovery and reuse of the graywater; a graywater recovery device communicably coupled to the controller and configured to recover the graywater from the graywater source of the building; and a graywater distributor communicably coupled to the controller, connected to the graywater recovery device, and configured to distribute the recovered graywater to at least one target position in the building for reuse, wherein the controller controls the graywater recovery device to deliver the graywater to the graywater distributor according to a control signal sent by a user, and the controller controls the graywater distributor to deliver the graywater to a target position designated by the user for reuse according to a control signal sent by the user.

A countertop assembly and method of making same. The method includes obtaining at least first and second layers that each include first and second alignment openings defined therein, disposing adhesive onto the upper surface of the first layer or the bottom surface of the second layer, stacking the second layer on the first layer, aligning the first alignment openings and aligning the second alignment openings, inserting a first alignment rod through the aligned first alignment openings, inserting a second alignment rod through the aligned second alignment openings, allowing the adhesive to dry to form a countertop stack assembly, and machining the countertop stack assembly to remove at least a portion of a surface of the first layer and at least a portion of a surface of the second layer to form a finished countertop assembly.

A sanitary equipment with a water supply system, a water route system, and a hand washing table are provided. The sanitary equipment includes a machine having a machine water outlet; a movable hand washing table pivoted on the machine and located below the machine water outlet, the movable hand washing table being capable of opening or retracting with respect to the machine; and a water route system disposed in the machine and connected to the machine water outlet to discharge potable water and non-potable water from the machine water outlet.

A conventional bathroom sink has an overflow port and an overflow conduit. A conventional drain pipe for the conventional sink has overflow ports in fluid communication with the sink's overflow port. A vessel sink does not have an overflow port. A prior art drain pipe that does not have overflow ports has been used with vessel sinks. The present invention provides a new drain pipe with overflow ports for a conventional sink and means for covering and sealing the overflow ports in the new drain pipe so that the new drain pipe can also be used with a vessel sink that does not have an overflow port. Means for covering and sealing the overflow ports include an inner sleeve that fits inside the drain pipe, an outer sleeve that surrounds the drain pipe and grommets and hole plugs that that fit inside the overflow ports, where all of the means cover and seal the overflow ports so that the new drain pipe does not leak when used with a vessel sink that does not have an overflow port.

A washstand arrangement with a fountain jet water discharge device. More particularly, a washstand device includes a washstand having a wash-bowl sink and a water discharge device, configured for discharging water in the form of a fountain jet composed of individual jets and comprising a plurality of water discharge nozzles which are arranged in the wash-bowl sink for discharging the individual jets in associated individual jet directions from the wash-bowl sink obliquely upwards and back again to the wash-bowl sink. The water discharge nozzles are arranged within a strip-type nozzle assignment region having a strip length extending in sink circumferential direction and a strip height perpendicular thereto, wherein its strip length is greater than its strip height, and its strip length extends at most across half the sink circumference.

A connector apparatus featuring a main pipe with first and second opposed ends. Each has a corresponding male-threaded fastening section for mating with the complimentary female-threaded fastening section on a respective conventional pipe-locking ring or collar. A valve-housing for supporting a one-way flow valve assembly interiorly, and a riser mounted on and supported by the valve housing for ultimate connection to the output or exhaust nozzle of a medical scavenger device.
