One 2lb. jar of RootX will be effective on 50 feet of pipe with a 4 inch diameter.

The patented RootX formula foams on contact with water to reach the top of the pipe where 90% of the roots are. Degreasing agents strip away grime so the RootX herbicide can penetrate the roots, killing them on contact. RootX sticks to the pipe walls, preventing re-growth for up to three years. Dead roots decay over time, restoring pipes to their full capacity.
