What Is a Septic Backup?

A septic backup occurs when wastewater from a septic system cannot properly flow through the tank and drain field. When this happens, wastewater may return through plumbing fixtures inside the home or appear on the ground above the septic system.

Septic backups are often one of the most noticeable signs that a septic system is not functioning correctly and may require inspection, pumping, or repair.
