1. A method of dispensing a solution of a fluid and a solid product, the method comprising the steps of:
connecting a first end of a fluid line to a fluid source;
connecting a first cartridge to a dispenser that is at a second end of the fluid line, the dispenser including a body, a fluid outlet defining a first outlet area and a second outlet area at the body, the first outlet area being larger than the second outlet area, and an actuator configured to allow selective communication of the fluid from the fluid source to the first cartridge, the first cartridge housing the solid product and including a fluid inlet and a solution outlet, the fluid inlet defining a first inlet area and a second inlet area, the first inlet area being larger than the second inlet area, the first cartridge being connected at the fluid inlet to the fluid outlet of the dispenser such that the first outlet area is connected at the first inlet area to cause a first rate of dissolution of the solid product and the second outlet area is connected at the second inlet area to cause a second rate of dissolution of the solid product that is different than the first rate of dissolution;
based at least on a type of solid product housed at the first cartridge, selecting one of the first rate of dissolution and the second rate of dissolution;
when the first rate of dissolution is selected, actuating the actuator to allow the fluid to be delivered to the first cartridge via the first inlet area and the first outlet area such that the fluid contacts the solid product housed in the first cartridge and dissolves at least a portion of the solid product at the first rate of dissolution forming the solution;
when the second rate of dissolution is selected, actuating the actuator to allow the fluid to be delivered to the first cartridge via the second inlet area and the second outlet area such that the fluid contacts the solid product housed in the first cartridge and dissolves at least a portion of the solid product at the second rate of dissolution forming the solution; and
outputting the solution at the solution outlet of the first cartridge.
