Apparatuses and methods for liquid control are provided. A liquid control apparatus may be for selectively treating and/or substituting a liquid flow from at least one of a plurality of supply lines. The ultimate liquid flow is for dispensing to a user by way of a liquid supply fixture such as a tap. The apparatus comprises a liquid conditioning module for connection in-line with at least one of the plurality of supply lines. The liquid conditioning module receives a diverted liquid flow of the at least one supply line from an upstream portion of the supply line. It then outputs a selectively treated and/or substituted liquid flow for returning to a downstream portion of the supply line for dispensing to the user. The apparatus has at least one flow sensor, each flow sensor associated with one of the plurality of supply lines. It has a controller, the controller configured to receive information indicative of the liquid flow of at least one of the plurality of supply lines from the at least one flow sensor. The controller, upon the occurrence of a predetermined flow characteristic, is operable to activate the liquid conditioning module to treat and/or substitute the liquid flow from one or more of the liquid conditioning module connected supply lines in order to provide a treated and/or substituted liquid flow at the liquid supply fixture.

A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate the measurement values determined by the at least one sensor. The central controller is designed to control the control elements depending on the received measurement values. The drinking water line system has a drinking water line section for supplying drinking water to multiple drinking water removal points. A volumetric flow rate sensor is provided in order to measure the volumetric flow rate of the water in the drinking water line section and/or a pressure sensor is provided in order to measure the water pressure in the drinking water line section. The controller is designed to carry out a measure.

The invention relates to an item of work furniture for sanitary applications, kitchens, or the like, for the defined arrangement of at least the following modules on a main body: a water supply module, at least one fitting module having a fitting that is connectable to the water supply module and/or to at least one water treatment module, and at least one drain module having a drain point for the at least one fitting of the fitting module and having a drain fitting, and at least the water treatment module is arranged interchangeably in the item of work furniture.

A hot water unit fluid supply control system comprises a switching device coupled to a hot water unit, a rainwater tank and a potable water source. The switching device is configured to selectively switch between a first state, which allows fluid communication between the hot water unit and the rainwater tank, and a second state, which allows fluid communication between the hot water unit and the potable water source. The hot water unit fluid supply control system comprises a control unit configured to: receive fluid characteristic information associated with fluid in the hot water unit from one or more sensors; activate or deactivate a pump of the rainwater tank based on a comparison of a fluid characteristic parameter of the fluid characteristic information with requirements of the hot water unit to thereby cause the switching device to assume the first or second state.

Apparatus and methods for improved hot water flushing of a water supply system.
