3. StoneAge WARTHOG Rotary Sewer Nozzle WHP 1 2 amp WHP 3 4 Description The Warthog Maximum Pull Rotary Sewer Nozzle was designed for waterjet cleaning of pipes and sewer lines Jet thrust powers rotation of the head and pulls the tool thru the line The Warthog WHP has both 1 2 NPT and 3 4 NPT threaded inlet nuts It is also available with 1 2 or 3 4 BSPP threaded inlet nuts The WHP is capable of working pressures up to 8000 psi 550 bar and flow rates of 10 to 45 gom The unit is filled with a thick viscous fluid that controls the rotation speed The nozzle orifice sizes should match the operating conditions of pressure and flow desired Hose length and size must be known to correctly determine the proper orifice sizes Contact your distributor or www sewernozzles com to help in nozzle selection The most important item in maintaining the Warthog is keeping the tool full of viscous fluid The tool also has a high pressure seal and seat that will need to be replaced if the tool begins to leak water from under the Weep Seal The tool may leak water at low pressure intermittently but if it leaks at operating pressure it is time to change the seal Operation A 15 25 foot long section of leader hose of a different color than the jetter hose is recommended to indicate how close the tool is to exiting the pipe during cleaning Flush the jetter hose to remove debris Pass hose end through the hose guard or Tiger Tail If the Warthog WHP
