Unless your model specifies that it is Batch Feed or BF, it is a continuous feed disposer.
Note: Both Continuous Feed and Batch Feed versions have the same grind process but different on/off switch mechanisms and modes of loading the food waste.
Continuous Feed models require a wall switch (or Air Switch option). Food waste is fed through the splash guard and can be added to the grind chamber all the time the unit is running.
Batch Feed Disposers include the On/Off switch in the throat of the Disposer and after food is placed in the grind chamber the switch is activated by the sink stopper. Only water is allowed to enter the Batch Feed unit whilst in operation. As soon as the sink stopper is removed the disposer automatically turns off.
