ABSTRACT:
A method of cleaning a linear discharge pipe that extends from a tank to a valve comprises attaching a cleaning apparatus to the discharge side of the valve on the discharge pipe. The valve is then opened and a rotating cutter head on the cleaning apparatus is advanced through the open valve and the discharge pipe until the cutter head has traversed the entire length of the discharge pipe. The rotating cutter head is then withdrawn back through the discharge pipe and the open valve. The valve is then closed and the cleaning apparatus is removed from the discharge side of the valve. Any portion of downstream piping that had been removed to allow access to the valve is then reinstalled to the discharge side of the valve.
