How long does a septic inspection take?

Most take one to three hours. Time depends on how easy the system is to find, whether the tank is pumped during the visit and how much testing is done on the drain field.

Should the tank be pumped before an inspection?

Many inspectors prefer to see the tank before and during pumping so they can judge how the system has been working. Ask the inspector what they want rather than pumping on your own beforehand.

Does Mokena require a septic inspection when a home is sold?

How often should I inspect my septic system?

A professional inspection every few years is a good habit, often at the same time as pumping. Systems with pumps, aerobic units or known problems may need more frequent checks.

Septic System Inspections for Mokena Homes

Most septic problems are cheaper to fix when they are found early. A professional inspection in Mokena checks how the system is built, how it is performing and whether anything is close to failing.

You might be under contract on a house or have owned your home for years. Either way, a local company that works across Will County can give you a clear written picture of your system.

The checklist an inspector works through

Expect the inspector to locate every component, measure how full the tank is, check inlet and outlet baffles for damage, and watch whether water flows the right way. Many also run water through the house to see how the system responds and walk the drain field for wet spots or odors.

Visual inspections and full inspections

A visual inspection is a quick check of how the system seems to be working, often by running water and looking for problems. A full inspection goes further: the tank is opened, levels are measured and the drain field is evaluated. For a home purchase in Mokena, a full inspection is usually the better choice because it finds problems a quick look can miss. Ask the company which type they are quoting before you book.

Inspections for buyers and sellers

Buyers use an inspection to learn what they are taking on. Sellers use one to fix problems before listing or to show buyers the system is sound. In either case, schedule early in the process so there is time to pump, make repairs or negotiate. Waiting until the last week before closing leaves little room if the inspector finds a problem.

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.

Getting the property ready

Clear access to the tank lid and drain field, unlock gates and keep pets inside. Let the inspector know about any past backups, alarms or repairs. If the home is vacant, ask whether water should be run ahead of time. the Will County health department may have records for the system that the inspector can use, so it helps to request them early.

Choosing a septic inspector

Look for an inspector who explains the process clearly, provides a detailed written report and is not rushing to sell you repairs. It is reasonable to ask whether the same company performs repairs and how they handle that. Experience with the types of systems common around Mokena and Frankfort, Orland Hills, Tinley Park is a plus.
