Abstract
A water filtration system and water filtration system head provide interchangeable water inlet and outlet ports, so that a direction of a flow of water through the water filtration system can be reversed by configuring a valve provided in the water filtration system head that attaches to a cartridge housing containing a water filter cartridge. The head has a first fluid channel communicating with a fluid volume between the cartridge housing and the outer surface of a water filter cartridge, a second fluid channel in communication with an inside of the cartridge, and a multi-position valve that either conducts inlet water from a first port to the first fluid channel and conducts outlet water from the second fluid channel to the second port, or conducts inlet water from the second port to the first fluid channel and conducts outlet water from the second fluid channel to the first port.
