1. A method of operating a water treatment system including a control valve unit coupled to a water treatment tank, wherein the control valve unit is configured to be used with a brine tank, and wherein a brine passage in the control valve unit is fluidly coupled to an air intake inlet and an air release outlet instead of a brine tank, the method comprising: treating the water in the water treatment system by directing water from a water supply to a water treatment tank, passing the water through an air charge to aerate the water, and directing treated water from the water treatment tank to a service water system; supplying air to the water treatment tank through the air intake inlet and the brine passage when a valve cycle actuator of the valve control unit is in a brine cycle position to provide the air charge; and releasing the air from the water treatment tank through the brine passage and the air release outlet when a valve cycle actuator of the valve control unit is in a brine tank fill cycle position.
