Abstract: A preheating backwater device comprises a tank body fabricated with a pump, a control module, a Y-pipe and a plurality of pipes inside. The device is assembled with a general hot-water heater and existing hot water and water supply pipes in a building. Users can activate the device either by pressing wire-linked buttons or using a wireless remote control. Lower temperature water in the hot water pipes can be pumped out and recirculated to the hot-water heater of the backwater device for a preset amount of time. If the automatic control module fails and preheating is not stopped automatically, an overheat protection device activates to guide the hot water to a cold water pipe via a backwater gate. A pressure control device installed in one end of a three-port connector of the overheat protection device stabilizes the pressure in the pipes. The design can prevent dangerous overheating situations.
