摘要：
A water filter is disclosed having a water reservoir in fluid communication with the porous ceramic core filter element and the drinking water control valve of a filter assembly, for holding a volume of water therein. The water reservoir provides a compressed air space, the air being compressed by an intake flow of water from the filter assembly. The compressed air in the water reservoir is released as a washing water control valve of the filter assembly is opened, thereby causing water from the reservoir to flow backwards through the filter element from inside out. This reverse flow carries dirt from small holes in the filter element, for draining from the washing water control valve.
