A massive clog in 1929 home cast iron drum or piping (wasn't using lint sleeves). I added two packs of Green Gobbler and the boiling water 20 minutes later. But no change. I added a third pack and left it overnight. I tried a cable snake and plunging in the am. No change. I added two gallons of boiling water then charged up the garden hose and routed it into the basement and shot stream into the drain while plugging the other twin drain in tubs. I prayed and ordered the clog gone in Jesus' mighty name. Honest, it broke up and left out. I used baking soda and vinegar for aftermath ick.
The home still smells like sewer, but I'm doing a load of laundry! Thank you for this product. Plumbers and Rooters wanted to saw off the drum and add plastic piping for $1000.
Bottom Line: Yes, I would recommend this to a friend
