FOR PROFESSIONAL USE ONLY. This product is a heavy-duty sewer solvent and drain opener specifically formulated to unclog and maintain municipal sewer lines.  It attacks the organic matter, such as paper and cellulose.  It saponifies grease, oil and fats and lubricates the line to speed up the flow of materials.  Its exothermic (high heat production) action is amplified by the addition of aluminum chips that agitate the sludge entrapping debris that causes most blockages. This product requires an additional shipping charge. Please call us at 770-934-4242 or toll free at 800-877-3339 to ensure you get the best price.
