The DM55 SPP sewer cleaning machine from Duracable has a maintenance-free gearbox, an indestructible frame and an industrial 3/4 hp motor that operates at 175 rpm to clear tough clogs. A power cable feed and return helps push and retrieve the drain cable at a steady rate to break up roots. Its 10-1 gear ratio delivers torque and horsepower. It can be combined with a spearhead or double saw blade for ideal root removal from residential, industrial and commercial mainlines. It is recommended to treat lines with a product such as RootX within an hour after root removal for maximum absorption and to prevent regrowth. 877-244-0662; www.duracable.com.
