ABSTRACT:
A portable, multiple purpose drain cleaning apparatus comprising a payout drum supporting a snake hose wound thereon and supported for rotation on a portable support frame, a plurality of fluid tanks in selective fluid communication with a powered pump connected to the snake hose, and a spray hose assembly for providing a source of high pressure fluid for external cleaning operations. A valve assembly is provided for alternately directing the pressurized fluid to the snake hose or to the spray hose assembly. A pressure sensing unit communicates with the spray hose assembly for selectively activating and deactivating the power source powering the pump in response to the pressure of the fluid in the spray hose assembly. In another embodiment a valve assembly is provided to define an open flow path of the fluid during start-up of the pump.
