The RIDGID KJ-3100 portable water jetter offers 3,000 psi of working pressure and 5.5 gpm of flow for fast, effective cleaning of large commercial and industrial lines. The jetter propels a flexible and lightweight hose through 2- to 10-inch lines, blasting through sludge, soap, grease and sediment blockages. As the hose is pulled back, it power scrubs the line, flushing debris away and restoring drainlines to their full, free-flowing capacity — all without the use of chemicals. Pulse action allows for easy negotiation of difficult bends and traps. It has a removable hose reel and Triplex pump with corrosion-resistant, forged brass head. It comes on a two-wheeled cart that easily fits through standard-size doors and negotiates tight turns with ease. 800/769-7743; www.ridgid.com.
