K77 POW DRN ROOT KILLER32OZ 17004029

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 regrow. Treatments at 6-12 months intervals may be necessary to control new or abnormally root intrusion. Non-corrosive and safe for all types of plumbing.
