SEWER Treat Before There is Complete Blockage
Apply up to 2 lb. Root Destroyer two times per year or anytime a reduced water flow thought to be caused by root growth occurs. Using one-half pound increments, pour Root Destroyer 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 amount directly into the sewer line; replace plug and flush the toilet several times.
