Abstract
A water filter cartridge for refrigerators is configured to indicate leakage when a cartridge is installed in a manifold having a larger diameter, male inlet and a smaller diameter, coaxial, male outlet. The filter cap has a cylindrical recess that mates with an O-ring on the manifold inlet during use. A fluid passageway extends through the wall forming that recess and opens immediately adjacent that O-ring to carry any leaking water to the outside of the filter cap. The filter cap has a seal on a smaller diameter recess that mates with the sidewall of the male inlet at a distal end thereof. The smaller diameter recess may have slots that allow water to bypass seals on the male outlet member. Under normal water pressure the system will immediately visually exhibit a substantial leak if the filter cartridge is incorrectly coupled to the manifold.
