An apparatus for automatically treating a drain system to prevent or at least minimize clogging problems particularly in grease traps of the type provided in restaurants and other food preparation establishments. The apparatus includes a valve for directing fresh water into the grease trap for pretreating the trap in preparation for the injection of bioactive liquid cultures by the pump. The liquid cultures liquify and digest contaminants in the grease trap which are flushed therefrom by fresh water. The apparatus is controlled by a system which cyclically operates the apparatus in accordance with a preferred operational sequence and at adjustably variable time periods.
