What Do I Do If Raw Sewage Backs up Into My Bathtub?

The first step is to stop using every faucet, toilet, and appliance that drains water. This includes showers, sinks, washing machines, and dishwashers. Continuing to use water will push more sewage into the tub and could spread contamination to other drains in your home.

Turn off the main water valve if you can find it safely. If you live in Kirkland, keep the shutoff valve location written down near your water meter so you can act quickly in an emergency. Avoid flushing toilets until the backup is resolved, because that adds more water to the system.

Once the immediate risk is managed, contact the pros who handle sewage backup cleanup. They have the proper equipment and training to remove contaminated water, disinfect surfaces, and dry the area safely. Do not attempt to clean raw sewage yourself, as it requires specialized handling.

The pros will assess the extent of the contamination, remove affected materials, and use industrial-grade disinfectants. They also check for hidden moisture in walls and floors that could lead to mold growth. In a mild marine climate with wet winters and dry summers, lingering moisture can be a problem, so thorough drying matters.

After the cleanup, ask the pros to identify the cause of the backup. Common causes include clogged pipes, tree roots in the sewer line, or a municipal sewer issue. A plumber can inspect your main drain line with a camera to find blockages or damage.

Consider installing a backwater valve on your main sewer line to prevent sewage from entering your home in the future. This device allows water to flow out but blocks it from flowing back. Regular maintenance of your plumbing, like avoiding flushing wipes or grease, also reduces the risk of backups.
