Dental office overflow.
It was just another day at the dental office until the toilet started backing up. The water kept flowing out until the bathroom was covered with two inches of water. The water began to seep out of the bathroom into the break room and waiting room. The dentist had the bright idea to place sandbags at the bathroom door to keep the sewage water from flowing out more until we could get there. We started extracting as soon as we arrived on scene. Since the water came from the toilet it's considered black water and needed a bacteria clearance test after the job was finished to ensure it was really clean.
