A sink system includes a sink basin and a discharge conduit coupled to the sink basin, which is positioned to expel fluid into the sink basin via an outlet thereof. The flow of fluid through the discharge conduit may be activated via a motion sensor or switch coupled directly to the basin or a spacer ring positioned between the basin and a countertop. Controls for adjusting the temperature and/or flow rate of fluid through the discharge conduit may also be coupled to the basin or a spacer ring positioned between the basin and the countertop, or alternatively, to a surface of the countertop. Methods of making and using sink systems are also provided.

A programmable system with user interface control for water flow rate or water temperature. Embodiments of the invention include a water temperature control system for a shower.

The invention relates to a heat recovery unit to transfer heat from a gray water source discharged from a bath or a shower to preheat fresh cold water supplying a bath, a shower, a boiler system or hot water heater. The heat recovery unit comprises an inner tube, an outer tube, a non-return valve, an anode, deflectors as well as associated piping and fittings. Fresh water from a pressurized public network or well flows through the inner tube while the gray water flows between the inner and outer tubes. The non-return valve installed in the fresh water pipe prevents contamination of the drinking water system. A translucent pipe may be installed in a section of the gray water piping system to detect any leaks. An insulated jacket may be placed around the unit to reduce heat loss. The heat recovery unit may be used in domestic, commercial, industrial and institutional buildings.

A water dispensing apparatus includes: a filter; a hot water tank; a water discharge nozzle; a hot water pipe connecting the hot water tank to the water discharge nozzle; a hot water discharge valve; a drain pipe branched from the hot water pipe; a drain valve disposed at the drain pipe; a first temperature sensor disposed in the hot water tank and configured to detect a first temperature of the hot water tank or water in the hot water tank; a second temperature sensor disposed in the hot water discharge valve and configured to detect a second temperature of water that is in the hot water pipe or introduced into the hot water discharge valve; and a controller configured to control the hot water discharge valve and the drain valve based on temperature information including the first temperature and the second temperature.

A domestic water tap (1000) is disclosed. The present application relates to a tap and an inner body for routing liquid within a tap, for example, a domestic water tap or faucet. The domestic water tap (1000) comprises an outer body (1010, 1012) and an inner body (100). The inner body (100) is housed within the outer body (1010, 1012). The outer body (1010, 1012) comprises at least one flow channel (1020, 1022) in which water can flow through the tap (1000) without contacting the outer body (1010, 1012). The inner body (100) is made from plastics and comprises at least one non-threaded bore for securely receiving a connector for delivering water from a source into the inner body (100).

A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

A hot water faucet system can include a housing, an outlet, a heating chamber, a valve assembly, and a handle. The valve assembly can include a valve assembly inlet, a valve body, a flow selector, and a valve cap. A handle is connected to and can rotate the flow selector within the valve body. The valve body includes a valve body aperture and the flow selector includes a notch. As the handle is rotated from zero degrees to approximately 90 degrees, the alignment of the notch, the valve body aperture, and the valve assembly inlet increases so that the flow of water from the valve assembly inlet increases. As the handle is rotated from approximately 90 degrees to approximately 160 degrees, the alignment of the notch, the valve body aperture, and the valve assembly inlet decreases so that the flow of water from the valve assembly decreases.
