A portable pipe cleaning apparatus is provided which comprises a tank capable of withstanding pressures of at least about 200 psi. A plurality of outlet valve means are in communication with the tank, with the valves adapted to be opened independently of each other. The valves function to allow a variable discharge from the tank. Means are provided for directing the discharge from the tank regulated by, and in communication with the outlet valve means. Means are also provided for charging an aggregate to dispense with the discharge. The apparatus is particularly adapted to be used with air and water under pressure by the alternate opening and closing of the valves providing a variable discharge of highly aerated water at a variable velocity.
