A water recirculating device, liter counter, and temperature regulator for showers, which allows the user to predetermine the water temperature required for any bathroom having cold water network and hot water network, whereby any water below the predetermined temperature is recirculated passing through the boiler of the house until it reaches the temperature preset in the device, wherein said device is composed of a housing, a temperature regulator, an LCD display, a LED ring, two water valves; a hot and cold water inlet; a three-way valve; a flowmeter connected to a pump; a thermostatic valve; a servomotor; and an integrated circuit board; and a method.

A device for a sanitary facility, intended for rapidly delivering Domestic Hot Water (DHW) to the supply points without wasting energy. The device according to the invention transfers the DHW rapidly from the source to the user as soon as there is a need for it. The method, which prevents any recirculation, makes it possible, in particular, to save the large amount of energy that is systematically wasted each time the DHW is distributed between its source and the supply points. The device essentially consists of a motorised, relatively powerful pump (2) which channels the DHW from the source (1) and injects it into a pipe with a very small cross-section (3) that conveys the entire flow rate required by the user at a high velocity to the supply point (41). An adapted sensor (5) controls the switching on and off of the motor pump (2) upon each use and controls its flow rate on the basis of the requirements. A single device can be used for supplying multiple supply points. It can be fitted to all new or existing facilities.

The object of the present invention is to provide a faucet apparatus in which both the area for the air inlet port and the area for the babble-water flow discharge port are secured, without excessively increasing sizes of a faucet aerator cap and a faucet apparatus. The air inlet port is provided in a lateral surface of the faucet aerator cap. The flow channel of the spout is provided with a communication port for guiding air between the outside wall and the flow channel toward the air inlet port.

The invention relates to the technical field of bath products and provides a faucet. The faucet comprises a water outlet part and a rotatable water outlet assembly. A water outlet end of the water outlet part is arranged horizontally, and the rotatable water outlet assembly is connected to the water outlet end. The water outlet assembly is rotatably arranged in the water outlet end and can rotate to allow water to be discharged upwards, downwards, leftwards, rightwards, forwards or backwards; in addition, the water outlet assembly can be pushed into the horizontal water outlet end to occupy less space when not used and to be protected.

A water outlet device with water stop and flow rate control comprises a body, a water stop assembly, and a flow rate control assembly. The body comprises a water outflow passage. The flow rate control assembly and the water stop assembly are disposed on the body, first ends of the water stop assembly and the flow rate control assembly are respectively disposed in the water outflow passage, and second ends of the water stop assembly and the flow rate control assembly are exposed out of the body to respectively define a water stop operation end and a flow rate control end. The water stop assembly comprises a first shaft that is operatively connected to the water stop operation end. The flow rate control assembly comprises a second shaft that is operatively connected to the flow rate control end.

A water recycling system embodying a tank used for collecting and recycling bathroom shower warm up water for other household needs. The collection tank is fluidly connected to the shower head via an engaged diverter valve by way of a first conduit. The collection tank may provide a second conduit and valve system operatively associated with the collected warm up water to the toilet or other household water needs.

A recirculation pump system provides the ability to recirculate water from a water heater outlet, back into a water heater inlet through a cold-water supply line. The recirculation pump system pumps heated water, which may have cooled to a sub-optimal temperature, into a water heater. The recirculation pump system provides the ability to use a plumbing network that does not contain a dedicated recirculation line. The recirculation pump system uses a water pump to circulate water, a temperature sensor to control system activation based on water temperature, and a check valve to control the direction of fluid flow. This recirculation pump system provides a minimally invasive way to install a recirculation system into a plumbing network that otherwise would not be able to accommodate recirculation functions, and service modern plumbing fixtures efficiently.

A cold water recycling and reusing apparatus includes a water inlet pipe, a cold water recycling apparatus, a recycling pipe, a cold water return apparatus, a return pipe, a recycling container, and a water outlet terminal. The cold water recycling apparatus is installed at a location near the water outlet terminal. The cold water return apparatus is installed at a location behind the cold water recycling apparatus. The cold water recycling apparatus enables cold water to flow into the recycling container via the recycling pipe. The cold water return apparatus draws the water in the recycling container into the water inlet pipe via the return pipe. The water is adapted to mix with hot water and flows out of the water outlet terminal.

Methods, systems, and devices are disclosed for implementing a water saving mechanism. In one aspect, a reservoir is provided to collect cold water while hot water is being heated. Once a desired temperature is reached, a valve is actuated to allow water to bypass the reservoir and be dispensed through a shower head. The reservoir can be used to dispense the cold water at a later time.

A motion-activated shower head adapter that saves water, energy and money and records the savings with a software analytics dashboard. The adapter allows cold water flow out when the shower is first turned on, and shuts off water flow once the water is heated. When the presence of the user is automatically detected, the shower flow resumes.
