Abstract
An apparatus for cleaning the interior sidewall of a large diameter tube includes a centrally-apertured circular brush plate adapted to fit within a lumen of the tube. A fluid conduit is mounted in the aperture so that an upper part of the fluid conduit is positioned above a plane of the circular brush plate and a lower part is positioned below the plane. A nozzle assembly is disposed in radial relation to the lower part of the fluid conduit. A hose provides fluid communication between a remote source of water under pressure and the fluid conduit. The circular brush plate is inserted into the lumen of the tube and is gradually advanced through the tube. The nozzle assembly is rotated about an axis defined by the fluid conduit as the circular brush plate is advanced through the tube so that water under pressure cleans the interior sidewall of the tube.
