Removable connector for filter system

A connector head for a water filter cartridge having a housing containing a filter material, comprising:

• a water filter cap having an open end and an opposed second end joined to the open by a wall, the water filter cap having a longitudinal axis encircled by the open end of the water filter cap;
• a first axial tube extending along the longitudinal axis and defining a first axial flow passage extending along a portion of the longitudinal axis of the water filter cap;
• a first lateral tube extending laterally outward and intersecting the first axial tube, the first lateral tube defining a first lateral tube passage in fluid communication with the first axial flow passage, the first lateral tube having a first opening in a sidewall of the first lateral tube at or adjacent to a proximal end of the first lateral tube;
• a second lateral tube extending laterally outward and intersecting at least one of the wall of the water filter cap and the second end of the cap, the second lateral tube defining a second lateral tube passage in fluid communication with an inside of the water filter cap, the second lateral tube having a second opening in a sidewall of the second lateral tube at or adjacent to a proximal end of the second lateral tube;
• and
• a tubular fitting intersecting at least one of the water filter cap or first lateral tube and extends along the longitudinal axis.
