The Model 727 cart-mounted hydrojetter from Spartan Tool is available in a true hybrid version, running on either gasoline or propane by flipping a lever. It can be operated indoors and outdoors without any loss of pressure or flow. It can be used to jet septic lines and drainfields, and produces 3,000 psi, which provides enough pipe-cleaning pressure to scour any line up to 6 inches in diameter, while its 4 gpm flow moves debris downstream. Pulse technology reduces line friction, allowing the unit to maneuver the corners of drainfields, while its 200 feet of 9/16-inch hose provides enough length to get through most fields in one shot. Standard equipment includes 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 electric start. 800/435-3866; www.spartantool.com.
