Line Capacity：3/4"~3" Cable：3/4", 5/16" or 3/8"(HE) Equipped with a variable speed power cable feed and variable speed motor, the Drain-Rooter PH makes drain cleaning jobs cleaner and easier. The Drain-Rooter PH feeds and retrieves the cable at up to 16 feet per minute. A four-foot guide hose eliminates cable whipping, dirty fixtures and messy floors. The Drain-Rooter PH is a real labor-saver on long jobs or when working in a cramped area where the weight of the machine could get burdensome. It can be operated in both horizontal and vertical positions to get closer to the drain opening.
