Inside a full septic inspection

A full inspection looks at the whole system, not just the tank. The inspector finds the tank and field, reviews any permits or past reports, opens the tank, and checks the liquid level, scum and sludge layers, baffles and filter. They then look at the distribution box, pumps and alarms if present, and the drain field area.

Inspection options to ask about

Common options include a basic flow test or a full inspection with the tank opened. Some inspectors pump during the visit so the tank can be seen empty, run a camera through the lines, or probe the drain field. Your inspector can recommend the right mix for the property. the St. Clair County health department may also have its own requirements for inspections tied to a sale or a permit.

Good times to schedule an inspection

The most common reason people in O'Fallon call for an inspection is a home sale. Other good times include before a renovation that adds water use and after heavy flooding. It also helps when you notice slow drains or odors, or when you move into a home with no records for the system. Regular inspections help you catch small problems before they turn into drain field replacements.

What a useful report includes

A useful report gives you facts you can act on: measurements of scum and sludge, the condition of each part, a sketch or photos of where things are, and clear recommendations. If repairs are listed, ask the inspector which ones are urgent and which can wait.

Getting ready for the inspector

Find any septic permit, the original design drawing and receipts from past pumping or repairs. If you know where the tank lids are, clear grass, mulch or snow from them. Let the inspector know about any past backups or wet spots, and plan for normal water use in the house beforehand.

What to ask when you book an inspection

Ask exactly what the inspection includes, whether the tank will be opened and pumped, and whether the drain field will be tested. Ask about their experience with your type of system, how long the report takes, and whether the report format is accepted by lenders in St. Clair County.
