Roebic Laboratories, Inc. K-77 2-Pound Root Killer
K-77 clears existing roots from pipes. Roots are destroyed at the point of entry into pipes. Re-growth is prevented because unlike root cutting machines, K-77 chemically kills roots. Once killed, the dead root "seals off" the point of entry and the root cannot re-grow. Non-corrosive and safe for all types of plumbing. Will work without harming surrounding trees, ground cover or the natural bacteria content in septic tanks and cesspools. Not for sale in Connecticut, Massachusetts, the Bay counties of California and the City of Golden in Jefferson County, CO. Banned for use in Septic Systems in Florida.
