Short answerA septic inspection usually pumps the tank, checks baffles and components, and looks for signs of a failing drain field like wet spots, odors, or backups. Pumping runs about $250 to $500. Replacing a failed system can run $4,500 to $14,000 or more depending on soil and design. The county health department keeps permits and sets rules.
What do inspectors check?
The tank, baffles, filters, distribution, and the drain field area. A home inspector may only note visible signs.
What are the common findings?
- Overdue pumping.
- Damaged baffles.
- Wet or lush spots over the drain field.
- Slow drains and backups.
How serious is it?
Pumping and baffle repairs are routine. Drain field failure is expensive.
