The Model 727 cart-mounted hydrojetter from Spartan Tool is available in a true hybrid version, running on either gasoline or propane at any time, simply by flipping a lever. This allows the operator to run this single unit indoors and outside, without any loss of pressure or flow. It can be used for jetting septic lines and drainfields, producing 3,000 psi, which provides enough pipe-cleaning pressure to scour any line up to 6 inches in diameter, while its 4 gpm of flow moves the debris downstream. Its pulse technology reduces line friction, allowing it to easily maneuver the corners of drainfields, while the 200 feet of 9/16-inch hose included with the unit provides enough length to get through most fields in one shot. It comes with 75 feet of 3/16-inch trap hose for tight bends, seven nozzles for various jetting situations, a washdown wand with adjustable nozzle, jetting gloves, easy winterization for cold climates and an electric-start motor. 800/435-3866; www.spartantool.com.
