RootX kills tree and shrub roots in sewer lines, storm pipes and septic systems, and prevents root regrowth. Available only through a plumbing professional, the patented RootX formula foams on contact with water to fill the inside of the pipe to reach all root growth. RootX is non-systemic and has no negative effects on the environment. Annual RootX treatments will help keep your drain system free of root growth and flowing freely.
