Abstract:
A water filter system, comprising:a bracket; a plurality of valve bodies, each mounted to said bracket, each having a canister connection structure, a valve input port, a filter feed port, a filter receiving port, a valve output port, a filter feed passage between said valve input port and said filter feed port, and a filter output passage between said filter receiving port and said valve output port; a plurality of filter canisters, each having a housing, surrounding a water filter having an input and an output, said housing having a valve connection structure removably engaged with said canister connection structure of a corresponding one of said plurality of valve bodies, a canister inlet port opening at one end on an exterior surface of said housing and opening to said water filter input at another end, a canister outlet port opening at one end on an exterior surface of said housing and opening to said water filter output at another end, wherein said canister inlet port cooperates with said filter feed port of said corresponding one of said plurality of valve bodies and said canister outlet port cooperates with said filter outlet port of said one of said plurality of valve bodies; a final water line connected at one end to said valve outlet port of a final of said valve bodies; a final filter outlet spigot, having an on-off valve, connected to another end of said final water line; a first T-connection water tap-off in said water path between said outlet port of said first valve body and said inlet port of said final valve body, having an inlet port, a first outlet port and a second outlet port; an intermediate water line connected at one end to said second outlet port of said first T-connection water tap off; and an intermediate, user-accessible output spigot having an on-off valve, connected to another end of said intermediate water line, wherein a first of said valve bodies has its valve inlet port connected to an external water source, said valve output port of each other of said valve bodies is connected by a water passage to said valve input port of another of said valve bodies to establish a water path from said valve input port of said first valve body to said valve output port of said final valve body, said water path passing through said water filter of each of said plurality of filter canisters, and wherein said housing engagement structure of at least two of filter canisters' respective housing have common structure for interchangeable engagement with at least two of said valve bodies.
