Abstract: A water filtering apparatus with water flow switch valve device includes a water container filled with filtering materials and a switch valve device. The switch valve device includes a valve seat, a split valve, a control rod, and a valve cover. The valve seat is provided with threaded holes for connection with water pipes. The split valve has an interior divided into two isolated and non-communicating chambers. The outer wall of the split valve enclosing the chambers is provided with spaced water holes. When the split valve is installed in the valve seat and the valve cover is assembled to the valve seat, the split valve may be used to control the direction of flow of water into the water container for purposes of filtering water or purging the water container.
