Abstract
A method of using a device for use in cleaning septic tanks, comprising a rotatable blade for breaking up the scum layer within a septic tank, power drive for turning the blade with sufficient power to break up the scum, and driveshaft for operably connecting the blade to the power drive. The device can be used as a septic tank agitator, in order to liquefy the scum, liquid and sludge components within the tank, within a period of time far shorter than the traditional method of back-flushing to disrupt the layer.
