Start with Records
Request an available system file from Knox County. Compare the approved bedrooms, layout and tank information with the property as it exists today.
What Can Be Checked
Accessible lids, liquid level, baffles, filters and visible damage help identify concerns. Buried or inaccessible parts limit what can be established.
Buying or Selling
Knox County offers a Verification/Septic Letter with records review and a property visit. A private condition report does not replace that service.
Share the History
Tell the inspector about recent pumping, backups, added bedrooms and problems after rain. A recent pump-out can temporarily mask drainage symptoms.
Use the Findings
Ask for observed defects, access limits and a clear next step. No inspection guarantees future performance or approves a planned addition.
