Stay flushed (in the good way), homeowners.
This guide focuses on the second scenario—when the whole house is backing up. Do not run dishwashers, washing machines, or flush toilets. Every gallon you add pushes wastewater closer to backing up into your bathtub. Stop using water entirely for at least 4–6 hours. Step 2: Locate and Check Your Septic Tank Access Find the two lids in your yard (usually green plastic or concrete). Pop open the inlet side (closer to the house).
Never lean your face directly over an open septic tank. Sewer gases are toxic and displacing oxygen. Use a long stick or pole from a safe distance.
