A brewer system is adapted to brew a beverage utilizing a cartridge packed with beverage grind such as coffee, tea, milk, and the like. The brewer system may include a pump adapted to draw the fluid from either a reservoir or a heater tank utilizing a vacuum pump. The pump may pass the fluid to a brewing chamber adapted to receive the cartridge and inject the fluid into the cartridge to brew a beverage. The pump may draw the fluid from a tube having a first end and a second end, the first end may be coupled to the pump, and the second end of the tube adapted may draw the fluid. A portion of the tube may be elevated above the maximum fill line of the fluid within the reservoir or the heater tank. An air switch may be coupled to the portion of the tube such that atmospheric air may enter the portion of the tube through the switch after a predetermined amount of fluid has been pumped through the tube to purge the cartridge of beverage.
