Frequently Asked Questions ## Why General Home Inspections Miss Septic Failures One of the most dangerous assumptions home buyers make is believing that a standard general home inspection covers the septic system. General home inspectors typically run water in the sinks for 10–15 minutes and look for sluggish drains inside the house. **They do NOT**: - Locate or excavate the buried tank lids. - Pump the tank to inspect the concrete integrity or baffles. - Perform a continuous hydraulic stress test on the leach field. - Camera inspect the lateral pipes for root intrusion, crushed PVC, or heavy biomat buildup. If a seller hasn't occupied the home for 30 days, the drain field may appear dry and functional during a 15-minute home inspection—only to completely back up within 48 hours of a family of four moving in and running the laundry. ## Key Items to Demand Before Closing - **Request the County Health Permit & As-Built Drawing**: Verify that the septic tank was legally permitted and that the bedroom count matches the system's design capacity. - **Require a Full Tank Pump-Out During the Inspection**: The inspector must look inside an empty tank to check for cracks, water backflow from the drain field, and baffle erosion. - **Verify Aerobic Maintenance Contracts**: If the home uses an aerobic treatment unit (ATU) with spray or drip irrigation, verify active service records and chlorination pump operability. ### Calculate Your Home's Specific Pumping Schedule Use our free EPA formula tool to calculate your exact years and months between pumping visits. ### Frequently Asked Questions #### Can I walk away from a contract if the septic fails inspection?
