A few days ago, a plumber came out to fix our clogged kitchen sink. Without telling my wife, he poured a bottle of sulfuric acid down the sink. My wife said she smelled fumes and said smoke came out when she opened the cabinet below the sink a few hours later. The next day, a different plumber from a different company came out and said we should throw out all opened containers of food, toaster, and coffeepot, and wash everything in the house, and only then it will be safe to move back in the house. We have been staying in a motel for 5 days now, and this has cost us hundreds of dollars. Are we overreacting? Should we take the original plumber to court over this?
