Septic System Inspections for Jennings Homes

Request a call and a septic company that inspects systems in Jennings and Northwoods, Moline Acres, Pine Lawn will explain what their inspection includes and when they can get out.

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. Louis County health department may also have its own requirements for inspections tied to a sale or a permit.

When an inspection pays for itself

An inspection is most valuable before money changes hands: when buying, selling or refinancing a home in Jennings. It is also worth doing after a backup, before adding a bedroom or bathroom, and when you move into a home and do not know when the system was last serviced.

What you get in the report

A good inspection report lists the tank size and material, the liquid level and the sludge depth. It covers the baffles, lid and any filter, how the drain field looked, and anything that could not be reached. It should say clearly whether the system was working at the time of inspection and list recommended repairs or maintenance. Photos are a plus. Keep the report with your home records.

How to prepare for an inspection

Gather any septic permits, past pumping receipts and repair records. Mark the tank location if you know it and make sure the area is clear. If you are selling, avoid pumping right before the inspection unless the inspector asks for it, since a freshly pumped tank can hide how the system has been performing. Make sure water is on in the house so the inspector can run fixtures.

What to ask before you book

Useful questions include: What will you check, and what is outside your inspection? Is the tank pumped during the visit? Do you include the drain field? How will you document what you find? Will your report meet what my lender or buyer needs? Clear answers make it easy to compare companies.

When to inspect even without a sale in Jennings

An inspection in Jennings makes sense after buying a home without records, after a backup or before an addition. It tells you the size, layout and condition of the system. Knowing that ahead of time helps you budget for pumping or repairs instead of being surprised by them.
