The J-3080 Jet-Set™ water jet drain cleaning machine clears stoppages at eight gallons per minute without risking pump damage if the water supply can't match the pump demand. A 12-gallon buffer tank mounted on its 1-1/4-inch tubular frame gives the safety margin needed to use this high flow jet on larger lines. It also has a low-water shut-off valve, a 20 hp Honda engine, a thermal relief valve and a backflow check valve and inlet filter.
