What NOT to Do During a Sewer Backup

A sewer backup is one of the most stressful plumbing problems a homeowner can face. While quick action matters, what you avoid doing is just as important as the steps you take. Sometimes, even well-meaning attempts can make the problem worse. As the go-to team for sewer repair in Belmont, CA, Bell Plumbing outlines what not to do when dealing with sewer backups to help protect your home and save you from costly damage.

Do Not Use Plumbing Fixtures

When wastewater has nowhere to go, running faucets, flushing toilets, or using appliances connected to drains will add more water to an already overloaded system. This often leads to additional backups in sinks, tubs, or floor drains. Avoid using any water in your home until the problem is corrected.

Avoid Using Harsh Chemicals

Many people reach for drain cleaners in emergencies, but these chemicals rarely address the actual cause of a sewer backup. Instead, they can corrode pipes and worsen the damage. Professional methods such as sewer cleaning are safer and more effective because they target the blockage directly without harming your plumbing.

Do Not Attempt DIY Pipe Work

Sewer systems are more complicated than they appear. Attempting to open or repair lines without the proper equipment can expose you to raw sewage and cause further damage underground. If the problem involves underground sewer pipes, specialized tools and expertise are required to diagnose and resolve the issue safely.

Here’s what you need to do:

Keep Clear of the Affected Area

Sewage contains bacteria, viruses, and other contaminants that pose health risks. Avoid contact with the water and keep children and pets away until cleanup is complete. Protective gear and proper disposal methods are necessary for safe handling.

Leave Structural Repairs to Professionals

If a backup has caused cracks, flooding, or other damage, it is not safe to attempt structural repairs on your own. Some situations may require sewer line replacement, which involves excavation or trenchless methods to correct broken pipes. A licensed professional can evaluate the damage and recommend the right approach.

Schedule Preventive Service

The best way to avoid severe backups is regular sewer maintenance. Routine inspections can detect small problems before they lead to major failures, keeping your system in working condition year-round.

A: Contact a licensed plumber immediately. Delaying service increases the risk of water damage and exposure to harmful contaminants.
