High-efficiency, high-speed drain cleaning chains from Picote Solutions attach to Picote Miller drive units. The Original and Cyclone range from 1 1/4 to 10 inches. The Cyclone opens up to the inside diameter of the pipe to descale and remove the finest of roots. The Original rolls around the inside of the pipe removing roots and heavy tuberculation. Special drill heads and removal tools are available for severe heavy-duty roots and blockages, all without damaging the host pipe. To prevent further root infiltration, the coating system seals and forms a watertight, noncorrosive pipe. This easy-to-use system coats the pipe using a coating pump and brush application to work the resin into the host pipe. 219/440-1404; www.picotesolutions.com.
