Multiplexed system for dispensing multiple chemicals to multiple destinations

A liquid chemical dispensing system for use with a plurality of liquid chemical containers, said system comprising:

• a first fluid transport means;
• a plurality of system input tubes;
• an input multiplexer coupling said plurality of system input tubes to said first transport means, said input multiplexer operatively coupling a selected system input tube to said first transport means, said input multiplexer including a plurality of first multiplexer tubes, at least a portion of each of said first multiplexer tubes capable of being pinched in order to restrict a flow of a chemical in said tube, a plurality of pinchers, each of said pinchers coupled to a corresponding first multiplexer tube, and pinchers pinching said corresponding first multiplexer tube if said corresponding first multiplexer tube is not selected;
• and a flow enabler coupled to a pincher corresponding to a selected first multiplexer tube, with each of said pinchers including a spring mechanism, said spring mechanism for establishing a force on said corresponding first multiplexer tube thereby pinching said first multiplexer tube;
• a water supply;
• and
• a second fluid transport means coupled to said water supply and to said first fluid transport means, wherein an output of said second fluid transport means comprises a solution of said selected liquid chemical and said water.

A liquid dispensing system having a reservoir of chemicals and a supply of water, said system comprising:

• a first fluid transport means adapted to create a flow of said chemicals;
• a system input tube;
• an input valve in fluid communication with both said first fluid transport means and said system input tube, with a portion of said input tube adapted to be collapsible and said input valve having a valve element including a pincher positioned proximate to said collapsible end portion, said pincher being resiliently biased to apply a spring force against said collapsible end to selectively pinch-off fluid flow therethrough, with a flow enabler operably coupled to said pincher to selectively reduce said spring force and allow fluid flow through said collapsible end;
• and
• a mixing apparatus coupled to both said water supply and said first fluid transport means, said mixing apparatus being adapted to create a flow of said water and mix said flow of water with said flow of chemicals, defining a dilute chemical flow.
