What should you do if your septic system is backing up?

April 5, 2026

Quick Answer

If your septic system is backing up, turn off the power to the pump, and do not use water until the backup has stopped. Then, check the septic system's drainfield for clogs or over-saturation, and consider using a backhoe to inspect and repair any issues.

Identify the Problem

The first step is to identify the source of the backup. If you’re experiencing a complete system failure, check the power to the pump, as a malfunctioning pump can cause the system to back up. Make sure the pump is turned off and do not use water until the backup has stopped. Next, inspect the septic system’s drainfield, which is usually located 10-20 feet from the septic tank, to check for clogs or over-saturation. A clogged drainfield can be caused by excessive water usage, poor drainfield design, or poor soil conditions.

Assess the Drainfield

To assess the drainfield, use a backhoe to dig a trench along the drainfield and inspect for signs of clogging, such as slow water flow or standing water. If the drainfield is clogged, you may need to use a trenching machine to clear the clog or replace the entire drainfield. It’s essential to follow local regulations and guidelines for septic system maintenance and repair, as well as to use proper safety equipment when working with heavy machinery.

Prevent Future Backups

To prevent future backups, consider implementing a maintenance routine to check the septic system’s condition regularly. Every 3-5 years, use a backhoe to inspect the septic tank and drainfield, and consider replacing the septic tank every 20-30 years. Additionally, be mindful of water usage and avoid using excessive water, as this can put additional strain on the septic system. By regularly inspecting and maintaining the septic system, you can help prevent costly repairs and ensure a safe and functional system.
