## Abstract

A liquid dispensing system is provided for automated dispensing of a plurality of liquid reagents into a recreational body of water. The liquid dispensing system includes a cartridge apparatus housing a plurality of liquid reagent containers, each containing a respective liquid reagent. A docking assembly is provided having a dock manifold device, and is releasably coupled to the cartridge apparatus between a first condition and a second condition. In a first condition, the cartridge apparatus can be removably coupled to the docking assembly, while in the second condition, the cartridge apparatus is lockably mounted to the docking assembly in a manner permitting fluid communication from the respective reagent container to respective fluid passages of the manifold device. The dispensing system further includes a dosing engine having a valve manifold device to selectively dispense the liquid reagents into the recreational body of water through a dispensing port.

## Claims

### Claim 1

A liquid dispensing system for automated dispensing of a plurality of liquid reagents into a recreational body of water, said system comprising:
a cartridge apparatus defining a cavity, and a cartridge front wall;
a plurality of liquid reagent containers containing a respective liquid reagent, each said reagent container being disposed in said cavity in a manner permitting access to each respective liquid reagent through the front wall;
a docking assembly having a dock manifold device, and releasably coupled to the cartridge apparatus between a first condition and a second condition, removably mounting the cartridge apparatus to the docking assembly in a manner permitting fluid communication through the cartridge front wall from the respective reagent container to respective fluid passages of the manifold device;
a dosing engine having a valve manifold device having a plurality of intake ports coupled to the respective dock manifold fluid passages, and a dispensing port to deliver the liquid reagents to the body of water, said dosing engine further including a valve assembly fluidly coupled to the valve manifold device to manipulate the flow distribution between the respective intake ports and the dispensing port for selective dispensing of the respective liquid reagents through the dispensing port and to the recreational body of water.
