Review on 🚽 Roebic K-97 Main Line Cleaner: Powerful Biodegradable Bacteria to Tackle Paper, Fats, and Grease in Sewer and Septic Systems - 32 Ounces by Joshua Gulledge

works wonders. I had a clog in my main drain. Every time I used the washing machine, it made a backup. Tried other chemical clog removers, tried diving, tried pressure to unclog it. Nothing worked until we used it. I poured it into the sewer, left it overnight. The next morning I filled the kitchen sink with hot water and drained it twice. You can hear it coming off and the drain was clean. We also used it to empty the washing machine. This is the only product that has worked for us. We always make sure we have a gallon or two on hand.
