FORMULA 411 is a formulated sewer solvent designed to unclog and maintain sewer lines. It is used in both municipal and industrial plants. It contains a highly synergized metallic complex to give exceptional exothermic reaction. FORMULA 411 is a powerful chemcial compound for dissolving tree roots in sewer lines. Its reaction is due to a metallic activator allowing a higher peak temperature. FORMULA 411 dissolves grease and oil faster through chemical reaction. It attacks stoppages further on down the line and removes sludge, impediments, debris, paper, rags and sediments instantly.
