The Model KJ-3100 portable water jetter from RIDGID offers 3,000 psi actual working pressure to handle large commercial and industrial applications. It propels a highly flexible and lightweight hose through 2- to 10-inch lines, providing flexibility without reducing strength. The hose blasts through sludge, soap, grease and sediment blockages, scrubbing the line to flush debris and restore drainlines to full capacity without the use of chemicals. It has a hose reel that can be removed to ease loading, and the unit is maneuverable, as the two-wheeled cart easily fits through standing doors and negotiates tight turns. The pulse action can be activated to negotiate difficult bends and traps. The reduced number of fittings, hoses and parts minimizes leaks and downtime. 800/769-7743; www.ridgid.com.
