A water control valve device includes a housing having one or more inlet orifices and greater openings for receiving water, and one or more check valves each having an inner casing engaged into the inlet orifice of the housing and an outer peripheral flange engaged in the opening of the housing, and each having a port for receiving water. The check valve includes one or more inclined surfaces for forming a closable and openable mouth which is openable when water flows into the casing and which may be closed for preventing the water from flowing out of the housing.
