A drain clearing nozzle apparatus for clearing debris from a pipe or other hollow body is described. The drain clearing apparatus includes: a nozzle mounting body comprising one or more inlets for receiving high pressure fluid, a primary outlet adapted for connection to a cutting head or turbine or cutting nozzle, and one or more secondary outlets adapted to connect to one or more penetrating nozzles so that in use a fluid flow from the one or more penetrating nozzles penetrates obstructions and debris to make an aperture therein sufficiently large for the nozzle mounting body to fit through. Also described is a method of clearing obstructions and debris from drains and/or other hollow bodies, the method including the steps of: making an aperture in the obstructions and debris with a penetrating nozzle mounted on a nozzle mounting body so as to fit the nozzle mounting body therethrough; passing the nozzle mounting body through the aperture; clearing the obstructions and debris from the drain or hollow body with flow from another outlet on the nozzle mounting body. |
