The RIDGID Model KJ-3100 portable water jetter provides 3,000 psi actual working pressure to handle large commercial and industrial drain cleaning applications. It propels a highly flexible and lightweight hose through 2- to 10-inch lines, blasting through sludge, soap, grease and sediment blockages. As the lightweight, nylon-braided hose is pulled back, it power scrubs the line, flushing debris away and restoring drainlines to their full, free-flowing capacity without the use of chemicals. It can be used with the Root Ranger 3000 jetter nozzle to completely clear obstructions. The head allows the nozzle to push its way through tough blockages, while the rear-facing turbo jet scours the drain clean and flushes away debris. 800/769-7743; www.ridgid.com.
