If you experience a sewer backup, keep everyone away from affected areas because the water can carry harmful bacteria and viruses. Avoid flushing toilets or draining sinks until the issue is resolved. Wear rubber boots and gloves if you must clean up, and contact a professional plumber or your local utility for safe removal and disinfection.
