Septic inspection
for a home sale in Tennessee.
Buying or selling a house on a septic system in West Tennessee? The tank is the part of the deal nobody looks at until it becomes a problem. Here is what an inspection actually covers, who usually pays, and what a bad finding means for the closing.
WHAT WE CHECK
Eight things a real septic inspection covers
A home inspector will note that the property has a septic system. That is not a septic inspection. This is what we look at when the tank is the thing that has to be right before money changes hands.
- Tank location and access
- We locate the tank and lids, note how deep they are, and flag whether a riser would make future service practical.
- Sludge and scum levels
- How full the tank is tells us whether it has been serviced and roughly how long it has been sitting.
- Tank condition
- Concrete condition, lid integrity, and any visible cracking or deterioration inside the tank.
- Inlet and outlet baffles
- A missing or broken outlet baffle lets solids escape to the drainfield. This is one of the most common findings and it matters to a buyer.
- Effluent filter, if present
- Whether there is one, whether it is clogged, and whether it has clearly never been cleaned.
- Drainfield surface condition
- Wet spots, ponding, unusually green strips, sewage odor, trees planted over the field, and vehicle compaction.
- Flow behavior
- We watch how the system handles water to see whether effluent is leaving the tank properly or backing toward it.
- Pump tank and alarm, where applicable
- On pumped or aerobic systems we check that the pump cycles and the alarm actually works.
TIMING
Where the inspection fits in the transaction
- Book early in the inspection period
- Septic findings can change the deal, so do not leave it to the last two days of a contract.
- Pump first when records are missing
- You cannot properly evaluate a tank you cannot see into. If nobody knows when it was last pumped, a pump-out and inspection together is the honest approach.
- Expect one visit for most homes
- A standard single-tank residential system is a same-visit job when the lids are accessible.
- Add time if lids are buried
- Locating and digging lids adds labor. Sellers who uncover them ahead of time keep the cost and the schedule tight.
- Get findings in writing
- You want a written summary you can hand to the agent, the buyer, or the lender.
WHO PAYS
Buyer, seller, or split
- Buyer-paid is the most common arrangement, as part of due diligence alongside the home inspection
- Seller-paid up front is increasingly common, since a clean report removes a negotiating lever before offers arrive
- Split arrangements happen, often seller pays the pump-out and buyer pays the inspection
- Lenders and some loan programs may require documentation on a private septic system, so ask early
Ask your agent about county health department requirements for your specific property. Rules around repairs and permits vary, and we will tell you what we see either way.
IF IT FAILS
What each finding means for the deal
- Broken baffle or missing filter
- Usually a repair, not a replacement. Cheap relative to the rest of the list and worth fixing before closing.
- Tank never pumped, heavy sludge
- A pump-out and a re-check. If solids already reached the field, that gets noted for the buyer.
- Saturated or ponding drainfield
- The serious one. A failing field is a major expense and usually becomes a price negotiation or a repair condition.
- Tank structurally compromised
- Cracked or deteriorating concrete means replacement planning, not a patch.
- Undersized system for the house
- A three-bedroom house on a system sized for two will keep having problems no matter how often it is pumped.
