Abstract
A water filter assembly is provided including a body defining a body cavity, a spool slidably positioned in the body cavity between an extended position and a retracted position, and a locking mechanism. The body cavity is also configured to receive a filter cartridge, which once fully inserted is configured to hold the spool in the retracted position. Additionally, when spool is in the retracted position, a body inlet of the body is in flow communication with a body outlet of the body through the spool and through the filter cartridge. The locking mechanism is provided to hold the filter cartridge in the fully inserted position.
