ABSTRACT:
New nozzles and methods for cleaning debris from drain pipes are disclosed. In one embodiment, the present nozzle comprises a nozzle body including a peripheral sidewall having a plurality of spaced apart peripheral through holes positioned to cause fluid from the interior space defined by the nozzle body to pass through the peripheral through holes in a direction substantially perpendicular to the longitudinal axis of the nozzle body. In addition, the nozzle body preferably includes a distal end wall having at least one longitudinal through hole positioned to cause fluid from the internal space to flow through the longitudinal through hole in a direction substantially parallel to the longitudinal axis of the nozzle body.
