Septic symptom checker
Short answer
Tick what you've noticed to get a next step. Sewage indoors or on the ground needs action now, so keep people and pets away and call your local health department. Slow drains throughout the house, wet ground or odors call for a check soon. This is general guidance, not a diagnosis.
How this checker works
It sorts common warning signs into four levels and shows the most urgent one that matches. The signs come from EPA guidance. The grouping is ours, so it can't tell you the actual cause.
Stay safe
Don't open a septic tank to check it. If you've been exposed to untreated wastewater, contact your health professional.
