Water quality maintenance system are disclosed herein. The systems are configured to automatically switch between an open state allowing for purging of water from a water line and a closed state preventing water flow. The systems comprise a controller is configured to automatically generate a control signal and a purge valve comprising an electromagnetic actuator in electromechanical communication with the controller. Also disclosed herein are fixtures comprising the systems and methods of using the systems.

The invention relates to a method for operating a circulation system comprising a cooling device with an input port and an output port for cooling water. The invention also relates to a circulation system for implementing said method.

A water management method for controlling at least one operational parameter of at least one water control device, wherein the operational parameter is associated with water used by the water control device, the method comprising: sending, from an electronic controller of the water control device, operational data associated with the operational parameter to an embedded electronic device; receiving, at the embedded electronic device, the operational data, and developing control data based on the received operational data and sending the control data to the electronic controller; and receiving, at the electronic controller, the control data and controlling the operational parameter of the water control device based on the received control data.

An improved, wholly mechanical, valve unit is provided to automatically allow for flow between a high temperature liquid line and a cooler temperature liquid line in order to maintain the immediate availability of hot liquid immediately upstream of the valve, especially for hot water used in a building. The valve unit of the present invention includes a thermally-activated, bi-metal, or more broadly bi-flexive, valve disc, and a smaller diameter valve seat that concentrically contacts the valve disc intermediate the outer circumference and the center of the disc. The bi-flexive disc is provided two-sided, circumferential support, thus substantially equalizing the pressure against both sides of the disc, even when in the closed valve position between the higher temperature, higher pressure, hot water line and the lower pressure cold water line. The valve opens when the temperature differential across the valve disc decreases below a preset amount.

A system and method of minimizing the time between opening a hot water valve and hot water reaching a point of use by temporarily diverting the water to another point of use. The system and method embody a thermally sensitive valve arranged so as to permit the flow of cool water from a hot water supply line to be diverted to a point of use that is insensitive to the temperature of the water provided. Embodiments of the invention may also comprise timers that function to limit the amount of time that water may flow to a point of use that is insensitive to the temperature of the water provided. Such embodiments may operate without user intervention or may require that a user or other device provide a signal that causes the invention to divert water to a point of use that is insensitive to the temperature of water provided.

A water circulation system having a feed line, a return line, a string that connects the feed line to the return line is disclosed. A temperature control unit connects the feed line to the return line, a consumer, a valve, at least one temperature sensor and a system control. A method is disclosed which includes the steps of determining a first temperature, a second temperature and a lowering time; detecting the water temperature; controlling the first temperature by controlling the valve; and controlling the second temperature by controlling the valve during the lowering time.

A digital water timer may include a main body, a water valve, a locating base, a driving base, and a timer. The main body has a water inlet and a water outlet, and a valve tube protrudes from a lateral side of the main body. The water valve connected to the main body is controlled by the timer to achieve on/off operation of channels inside the main body. The locating base is secured on the main body, and the driving base is adapted to have rotation relative to the locating base and be secured at a specific position after rotated. The timer installed in the driving base comprises a display panel and an operation interface which are exposed externally for operation. The driving base with the timer is rotated relative to the locating base, and the display panel is adjusted as needed to provide an optimal view for operation.
