A dispenser for the mixing and dispensing of chemicals is provided which utilizes a draw-through distribution manifold connected to a number of concentrated chemical base solution containers. Solenoids corresponding to each chemical base are selectively operable to allow one chemical at a time to run through the manifold and a pump connected to the manifold outlet to be mixed with water from a general solenoid valve. A system for flushing the manifold is provided wherein a flush port is provided at the opposite end of the distribution manifold from its outlet. After each chemical has run for a period through the manifold, the flush system operates to accurately dilute the dispensed chemical and flush the manifold.
