Abstract:
A system for providing purified water to a point of use (POU) from a municipal water source or the like, which system comprises:a plurality of individual modules each of which includes a separable head and a canister, each of said heads having liquid inlet and outlet passageways, and means joining said heads of said plurality of modules one to another to create a composite manifold, said heads being of substantially identical construction and said canisters being of substantially identical construction so that such can be inexpensively manufactured, said canisters being hollow and having at least two interengaging sections including an upper section which mates with said head and a lower section, said hollow canisters containing different operating units, with at least one of said units being a pump and another being a purification unit, said upper section of each of said canisters containing an adaptor that creates a desired liquid flow arrangement between said inlet and outlet passageways in said head and the respective operating unit in said canister, and said modules in said composite manifold being interconnected for liquid flow between adjacent modules and being arranged so that said module containing said pump is upstream of said module containing said purification unit, whereby any canister of any module, including that containing said pump, can be easily and quickly replaced with a substitute.
