ABSTRACT:
The present invention relates to an improved water filter which comprises a cone-shaped tank, a filtering bed layer, four conduits provided in the tank and concealed in the filtering bed and a four-way valve provided on the outer wall of the tank at the junction of the conduits which allows passage between any two adjacent conduits by means of a moveable plug operated in a predetermined turn so that the filtering and backwashing process of the tank can be easily controlled by the valve in practical use and the filtering bed is prevented from boiling and cracks along the side walls of the tank.
