Zep Root Kill - 32 oz (Case of 4) ZROOT24 - Root Killer for Clogged Drain

Root control in septic tanks, leach lines and leach line pipes: The majority of the copper sulfate will settle in the septic tank itself and little will pass into the leach lines. To treat leach line pipes, add 2 pounds of Root Kill to the distribution box located between the septic tank and leach lines. To achieve effective root control in the leach lines it is necessary to transfer Root Kill from the septic tank to the leach lines. A cleanout plug opening may need to be installed if the distribution box does not have an opening leading to the leach lines. Repeat in 6 or 12 month intervals, if necesarry. Note: It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.
