Water purification system

A water purification system for a home brewing operation comprising:

• a housing having generally rectangular top and bottom walls and generally rectangular sidewalls interconnecting the top and bottom walls;
• a reverse osmosis filter having a longitudinal axis, a sidewall surrounding the longitudinal axis of the reverse osmosis filter, and first and second ends spaced along the longitudinal axis of the reverse osmosis filter, an inlet at the first end of the reverse osmosis filter, a permeate outlet at the second end of the reverse osmosis filter, and a retentate outlet at the second end of the reverse osmosis filter, wherein the reverse osmosis filter is located within the housing with its first end facing a shorter one of said sidewalls of the housing, wherein the longitudinal axis of the reverse osmosis filter is generally parallel to a longer one of the sidewalls of the housing, and wherein the sidewall of the reverse osmosis filter is adjacent to said longer one of the sidewalls of the housing;
• a sediment filter having a longitudinal axis, a sidewall surrounding the longitudinal axis of the sediment filter, and first and second ends spaced along the longitudinal axis of the sediment filter, an inlet at the first end of the sediment filter, an outlet at the second end of the sediment filter, wherein the sediment filter is located within the housing with its first end facing said shorter one of said sidewalls the housing, wherein the longitudinal axis of the sediment filter is generally parallel to said longer one of said sidewalls, and wherein the sidewall of the sediment filter is adjacent to the sidewall of the reverse osmosis filter;
• a carbon filter having a longitudinal axis, a sidewall surrounding the longitudinal axis of the carbon filter, and first and second ends spaced along the longitudinal axis of the carbon filter, an inlet at the first end of the carbon filter, an outlet at the second end of the carbon filter, wherein the carbon filter is located within the housing with its second end facing said shorter one of said sidewalls, wherein the longitudinal axis of the sediment filter is generally parallel to said longer one of said sidewalls of the housing, and wherein the sidewall of the carbon filter is adjacent to the sidewall of the sediment filter;
• a deionizing filter having a longitudinal axis, a sidewall surrounding the longitudinal axis of the deionizing filter, and first and second ends spaced along the longitudinal axis of the deionizing filter, an inlet at the first end of the deionizing filter, an outlet at the second end of the deionizing filter, wherein the deionizing filter is located within the housing with its second end facing said shorter one of said sidewalls, wherein the longitudinal axis of the deionizing filter is generally parallel to said longer one of said sidewalls of the housing, and wherein the sidewall of the deionizing filter is adjacent to the sidewall of the carbon filter;
• an automatic shut-off valve having a longitudinal axis, a sidewall surrounding the longitudinal axis of the automatic shut-off valve, and first and second ends spaced along the longitudinal axis the deionizing filter, first and second inlets at the first end of the automatic shut-off valve, first and second outlets at the second end of the automatic shut-off valve, wherein the first inlet and the first outlet of the automatic shut-off valve define a first flow path, wherein in the second inlet and the second outlet of the automatic shut-off valve define a second flow path that is separate from the first flow path, wherein the automatic shut-off valve is located within the housing with its first end facing the other one of the shorter ones of said sidewalls, wherein the longitudinal axis of the automatic shut-off valve is generally parallel to said longer one of said sidewalls of the housing, and wherein the sidewall of the automatic shut-off valve is adjacent to the other one of the longer sidewalls of said housing;
• and
• a flow restrictor having a longitudinal axis, a sidewall surrounding the longitudinal axis of the reverse osmosis filter, and first and second ends spaced along the longitudinal axis of the flow restrictor, an inlet at the first end of the flow restrictor, an outlet at the second end of the flow restrictor, wherein the flow restrictor is located within the housing, wherein the second end of the flow restrictor faces said shorter one of said sidewalls of the housing, wherein the longitudinal axis of the flow restrictor is generally parallel to said longer one of said sidewalls, and wherein the sidewall of the flow restrictor is adjacent to the other one of the longer sidewalls of said housing.
