  • Patent number: 6224353
    Abstract: A remote pump control apparatus and method that allows a septic tank service worker to physically control the end of the evacuation hose and operate a conventional pump which induces flow therein while servicing a septic tank including an actuator that mounts on and manipulates the flow control of the pump. The compressed fluid-driven actuator is controlled by a hand-held remote signal sender. A septic tank service worker depresses a switch on the hand-held remote signal sender and generates a signal which is received in a control box. The control box activates a solenoid which directs compressed fluid into one passage of a housing of the actuator, causing the actuator to manipulate the pump flow control in one direction, and into another passage, causing the actuator to manipulate the pump flow control in an opposite direction.
