Check the toilets, sinks and drain pipes to clear any blockages to ensure that the water is not due to an internal plumbing problem. It’s important to know that a wastewater backup is contaminated and may contain a number of bacteria and viruses, which can affect your health.
Try to carefully close as many drain openings as possible.
Don’t run any more water, use the toilets or send any water down the drain as it will likely end up in your basement or lower levels of your home.
Check with your neighbors to see if they are experiencing any backups. If they are, it is likely that it is a problem in the main sewage line. Contact the District immediately to report the problem.
Call a plumber to assist with clearing the issue, closing any drains remaining open, and to assess your home’s internal issues.
Contact your homeowner’s insurance to determine what coverage might be available.
