A water purifier generally associated with a beverage dispenser is disclosed. The water purifier includes a first conduit having a first end and a second end opposite to the first end, a second conduit having a first end and a second end opposite to the first end, a cistern disposed between the first and second conduits, and a water purifying device disposed in the flow path of either the first conduit or the second conduit. The first end of the first conduit is arranged to conduct water to be purified into the first conduit, and the second end of the second conduit is arranged to conduct the purified water from the second conduit to a location outside of the water purifier. The flow of the water from the second conduit to the first conduit is completely prevented and interrupted whenever the water attempts to flow from the second end of the second conduit to the first end of the first conduit through the arrangement of the second end of the first conduit and the cistern.
