Taco 554-6 0011CF Under Sink Installation Kit The D-MAND System is a small, silent pump that you attach to the hot and cold water lines in the cabinet under the most remote kitchen or bath fixture in the home. When the D-MAND System is activated, the cool water you normally let run down the drain is recirculated back to the water heater through the cold water line. On demand, the pump circulates hot water from the water heater and returns the cooled water back through the cold water line.
