If you see water backing up from a drain or toilet during a storm, stay out of it—sewer water can contain bacteria and viruses. Shut off the water supply to the affected fixtures and wear rubber gloves, boots, and a mask if you need to move anything. Open windows for ventilation, and call a plumber to clear the blockage safely before turning water back on.
