Welcome to Zep Inc. !
Root Kill dissolves the roots of trees and shrubs penetrating cracks of poorly sealed joints in pipes. The professional-strength, granular formula works on contact but does not harm trees and shrubs. It is safe for septic systems and pipes.
When a reduced water flow is first noticed, and root growth is thought to be the cause, treat with product. It is important not to wait until a stoppage occurs because some water flow is necessary to move copper sulfate to the area of the root growth. Usually, within 3 to 4 weeks, after roots have accumulated sufficient copper sulfate, the roots will die and begin to decay and water flow should increase. As the roots regrow, follow up treatments with copper sulfate will be required. Applications may be made each year in the spring after plant growth begins, during late summer or early fall, or any time a reduced water flow, thought to be caused by root growth, occurs. Apply 2 to 6 pounds of product two times a year to household sewers. Add product to sewer lines by pouring about 1/2 pound increments into the toilet bowl nearest the sewer line and flush, repeat this process until the recommended dose has been added, or remove cleanout plug and pour entire recommended quantity directly into the sewer line. Replace the plug and flush the toilet several times.
Pro-Tip: To maintain normal water flow in your drains, use this product twice a year as a preventative maintenance treatment against slow or clogged drains. Sign up for our Pro Care Reminders from the Zep Commercial home page to help you remember the date!
