Septic Tank Problems: Smells, Slow Drains, Backups & Wet Yard

Check common signs of septic trouble, including bad smells, slow drains, sewage backup, alarms and wet areas near the drain field.

Record the symptom

Note when the problem began, which fixtures are affected and whether an alarm or outdoor wet area is present. Use the troubleshooter for an initial next-step checklist.

Do not wait on sewage

If wastewater backs up or appears at the surface, reduce water use, avoid contact and seek professional assistance promptly.
