What Do I Do If My Sewer Line Backs Up?

If your sewer line backs up, the first signs can be easy to spot but hard to ignore. You may notice multiple drains in your home moving slowly at the same time, gurgling sounds coming from toilets or tubs, or wastewater backing up into the lowest drain in your home, often a basement floor drain or a first-floor shower. In more serious cases, flushing a toilet can cause water to rise in a nearby tub or sink instead of draining properly.

Stop Using Water Immediately

The most important thing to do is stop using water in your home immediately. Unless you’re looking forward to a high-stakes game of “The Floor Is Lava,” avoid flushing toilets, running sinks, or using appliances like your dishwasher and washing machine. Every gallon of water you send down the drain can add to an already blocked system and make the backup even worse.

Contain the Sewer Backup and Protect Your Home

If water is actively coming up through drains, try to contain the area to prevent damage to flooring or belongings. You can also shut off water to the home if the situation is severe. Avoid direct contact with wastewater, and keep children and pets away from the affected area because sewage can contain harmful bacteria and contaminants. Avoid attempting to remove or break into drain lines yourself since sewer issues are often found in the main sewer line and are deeper in the system than typical household plumbing.

What Causes a Main Sewer Line Backup?

Tree roots are one of the biggest culprits behind sewer line backups. As they grow, they’re naturally attracted to the moisture inside sewer pipes. If they find a small crack or gap in the line, they’ll grow right into it. Before long, those roots start catching everything flowing through the pipe, creating a clog that can send wastewater back into your home.

Backups can also be caused by grease buildup, collapsed or damaged sewer lines, and heavy debris clogging the main line. In older homes, shifting soil or deteriorating pipes can also contribute to recurring blockages. Even something as simple as flushing items that should not go down the drain can lead to a major blockage over time. If you have kids at home, now might be a good time for a reminder that toilets aren’t trash cans.
