Abstract: A humidifying system includes a water panel, and a distribution tray, where the distribution tray provides water to the water panel. The system includes at least one eductor fluidly coupled to the distribution tray and a scale control tray. The system also includes a valve assembly fluidly coupled to a water supply at a first inlet and is fluidly coupled to the at least one eductor via an outlet, where the valve assembly controls water flow through the at least one eductor. The valve assembly includes a second inlet in fluid communication with the scale control tray, where a wastewater flow from the scale control tray through the second inlet is controlled by a first valve and a freshwater flow from the water supply through the first inlet is controlled by a second valve. A configuration of the first valve is based on an operational state of the second valve.
