A drinking water supply system includes a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, and a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor. The system also includes a presence detector designed to determine information about the presence of a person, or an acoustic sensor designed to measure measuring values for the volume. The central control device is designed to control the drinking water supply system as a function of the information about the presence of a person or as a function of the measured values for the volume. A method for controlling such a drinking water supply system and a computer program that causes the method to be carried out are also provided.

This disclosure relates to a sanitary fitting for dispensing prepared liquids, for example, for beverages. A disclosed system includes a first control element for setting a quantity of the prepared liquid to be dispensed and an actuating element for providing the quantity of prepared liquid set by means of the first control element, wherein at least one second control element is configured to select a type of preparation, for example, from at least two different types of preparation, of non-prepared liquid, wherein the first and the at least one second control element are actuatable independently of one another.

The present disclosure provides a water supply system. The system comprises a central water supply, a plurality of water taps, at least one operation device located at one water tap, a piping system connecting the central water supply and the plurality of water taps, the piping system comprising a separate flow path from the central water supply to each water tap, and a controller for individually controlling a flow of water from the central water supply to the plurality of water taps and individually controlling an outlet temperature of the flow of water at an outlet of the central water supply. The controller is located at the central water supply, and the controller is operable via the operation device at the water tap.

A customized water outlet setting method, a customized water outlet method for a quantitative faucet, and a quantitative faucet are provided. The method comprises receiving a first touch/press signal of a water outlet setting switch, and entering a customized setting mode; receiving a quantitative gear position setting signal of a flow selection switch, and obtaining a corresponding quantitative gear position as a customized water outlet gear position; receiving a second touch/press signal of a water outlet control switch, controlling a water outlet valve to be opened, and controlling a flowmeter to start flow counting; after receiving the second touch/press signal of the water outlet control switch again, controlling the water outlet valve to be closed, and controlling the flowmeter to end the flow counting; setting a capacity obtained by the flowmeter as a water outlet capacity corresponding to the customized water outlet gear position; and exiting the customized setting mode.

A shower system includes a sprayer removably coupled to a receiver that is in moving engagement with a track. The shower system includes a control system operably coupled with the receiver. The control system can change a height of the receiver along the track.

A faucet having a pressure-sensitive surface for dynamically adjusting the faucet's water flow rate and/or temperature based on an amount of pressure applied to the surface of the faucet is disclosed. A pressure sensor may be electronically connected to one or more electronic valves of the faucet to control the flow of water through either the cold or hot water lines, thereby controlling the flow rate and/or temperature of water coming from the faucet.

The present invention provides an electronic plumbing fixture fitting including a learning system and a reference system. The electronic plumbing fixture fitting includes a user input module and a processor. The user input module includes a mechanism to receive from the user numerical value(s) of parameter(s) for water to be delivered through a discharge outlet of the electronic plumbing fixture fitting (e.g., a temperature) and a mechanism to deliver to the user the numerical value(s) of the parameter(s) via the water delivered through the discharge outlet of the electronic plumbing fixture fitting. Additionally, the processor includes a mechanism to learn a range of the numerical value(s) of the parameter(s) from a minimum value of the parameter to a maximum value of the parameter (e.g., from a lowest achievable temperature to a highest achievable temperature).

The present invention relates to systems and methods for reducing microbial contamination, particularly biofilm formation, in plumbing fixtures. In particular, the invention provides a computer implemented method for counteracting biofilm formation in a plumbing fixture, and a plumbing fixture in which the method may be applied. The method comprises: monitoring a parameter relating to microbial presence within the plumbing fixture, for example using a sensor; determining a level of risk related to biofilm formation based on the monitored parameter, for example based on sensor data; and in accordance with the determined level of risk, applying a countermeasure to the plumbing fixture in order to counteract biofilm formation.

The invention relates to a sanitary fitting that is comfortable to use for outputting mains water and prepared water of at least one preparation type, in particular filtered and/or boiling and/or chilled and/or carbonated water, wherein at least one control unit is provided for controlling the respective water flow of the mains water and/or the prepared water, and an operating unit is provided for contactlessly influencing at least one of the water flows, in particular both water flows, and for generating and forwarding control signals to at least one of the control units.

A pot filler including a metered dispense input device for dispensing of predetermined volumes of water. The pot filler illustratively includes an electrically operable valve operably coupled to a metered dispense input unit, and a control module configured to control operation of the electrically operable valve.
