The Vaporooter scientific formula is guaranteed to destroy roots on contact and inhibit regrowth for years. A combination of two unique herbicides approved for use in sewers create a devastating one-two punch on roots by penetrating root cells to destroy roots on contact, and binding to pipe walls, joints and cracks to inhibit new growth. Application equipment allows operators to simply jet up the line, push a button and fill the pipe with Vaporooter foam while retrieving the hose. The system fits any jet truck and is available as an option from many leading truck manufacturers. 800/841-1444; www.vaporooter.com.
