RootX is registered with the EPA to kill pipeline roots. It can be used by drain cleaning professionals as an effective tool and profitable add-on service. The foaming action lifts the root-killing active ingredient to the top of the pipe, where 90 percent of the root growth occurs. It also sticks to the top of the pipe and roots to keep blockages caused by root regrowth from occurring for up to 12 months. The simplicity allows drain cleaning professionals to bring on an additional service at minimal cost. 800/844-4974; www.rootx.com.
