In the treatment of water, an end piece is connected to a treatment cartridge housing and inserted into an appliance having bypass, inlet, and outlet valves. The end piece has an end piece wall from which an inlet fitting, outlet fitting, and protrusion extend. The inlet fittings, outlet fittings, protrusion, and cartridge housing each have a longitudinal axis. The inlet and outlet fittings have a cam surface for actuating the inlet and outlet valves, respectively. Further, the cam surfaces of the inlet and outlet fittings are angled and vectored in relation to their respective longitudinal axis. The protrusion is shaped for actuating the bypass valve.

What is claimed is: 1. An end piece for operatively engaging a head assembly, the head assembly comprising one or more valves, for the treatment and control of fluid passing through the head assembly, said end piece comprising: A. an end piece wall; B. an inlet fitting having a cam surface, said inlet fitting having a longitudinal axis; and C. an outlet fitting; and D. a protrusion having a longitudinal axis; Wherein said inlet fitting, said outlet fitting, and said protrusion extend from said end piece wall, wherein said protrusion is positioned between said inlet and said outlet fittings, wherein the distance from said longitudinal axis of said inlet to said longitudinal axis of said outlet is less than the distance from said longitudinal axis of said inlet to said longitudinal axis of said protrusion, and wherein the distance from said inlet to said longitudinal axis of said protrusion is greater than the distance from said longitudinal axis of said outlet to said longitudinal axis of said protrusion, wherein the distance from said longitudinal axis of said inlet to said longitudinal axis of said outlet is about 2 cm, and wherein the distance from said inlet to said longitudinal axis of said protrusion is about 2 cm, and wherein the distance from said longitudinal axis of said outlet to said longitudinal axis of said protrusion is about 2 cm, and wherein at least a portion of said cam surface is vectored from said longitudinal axis of said inlet fitting. 2. A unit for use in the treatment of fluid, said unit comprising: A. An end piece, said end piece comprising: i. An end piece wall; ii. An inlet fitting having a cam surface distal a sealing surface for actuating an inlet valve, said inlet fitting having a longitudinal axis, said inlet valve having a follower; iii. An outlet fitting for actuating an outlet valve, said outlet fitting having a sealing surface and a longitudinal axis; and iv. A protrusion for actuating a bypass valve; Wherein said inlet fitting and said outlet fitting extend from said end piece wall, and wherein a portion of said cam surface of said inlet fitting is vectored from at least one of said longitudinal axis of said inlet fitting and said longitudinal axis of said outlet fitting; and B. A head assembly, said assembly comprising: i. An inlet receiving port housing for receiving said inlet fitting, said inlet receiving port housing containing at least a portion of said following of said inlet valve; ii. An outlet receiving port housing for receiving said outlet fitting; and iii. A bypass passageway housing which contains said bypass valve, wherein said bypass housing is so arranged to receive said protrusion and said bypass valve is actuated by said protrusion; Wherein said inlet and outlet receiving port housings are so arranged to receive said inlet and outlet fittings, respectively, and said inlet and outlet sealing surfaces seal between said inlet and outlet fittings and said inlet and outlet receiving port housings, respectively, and said follower of said inlet valve is actuated by said cam surface. 3. The unit of claim 2, wherein said protrusion is positioned between said inlet and said outlet fittings. 4. A cartridge for operatively engaging a head assembly, the head assembly comprising one or more valves, for the treating and control of fluid passing through the head assembly, said cartridge comprising: A. An end piece, said end piece comprising: iv. an end piece wall; v. an inlet fitting having a cam surface, said inlet fitting having a longitudinal axis; vi. an outlet fitting having a cam surface, said outlet fitting having a longitudinal axis; and vii. a protrusion having a longitudinal axis and positioned between said inlet fitting and said outlet fitting; Wherein said inlet fitting, said outlet fitting, and said protrusion extend from said end piece wall; and B. A cartridge housing having a first end, a closed second end, and a longitudinal axis extending therebetween; Wherein said end piece wall is connected to said first end of said cartridge housing, and wherein a portion of said cam surface of said inlet fitting is vectored from at least one of said longitudinal axis of said inlet fitting, said longitudinal axis of said outlet fitting, and said longitudinal axis of said cartridge housing, and wherein a portion of said cam surface or said outlet fitting is vectored from at least one of said longitudinal axis of said inlet fitting, said longitudinal axis of said outlet fitting, and said longitudinal axis of said, cartridge housing.
