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.

Is a home inspection enough for a septic system?

Usually not. General home inspectors often do only a quick look at the septic system. A septic company opens the tank and evaluates the drain field, which gives a much more complete picture.

Who pays for a septic inspection during a sale?

It depends on your contract and local practice. Buyers often pay for their own inspection, while some sellers order one before listing. Your real estate agent can tell you what is typical in Des Peres.

What happens if the inspection finds a problem?

You get a clearer picture of what needs fixing and how urgent it is. Small items like a broken baffle are usually simple. Bigger findings, like a failing drain field, may call for repair quotes before a sale moves forward.

Septic Inspection in Des Peres, MO

Most septic problems are cheaper to fix when they are found early. A professional inspection in Des Peres 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 St. Louis County can give you a clear written picture of your system.

What a septic inspection covers

A full inspection usually starts with locating the tank and drain field and reviewing any records on file. The inspector opens the tank, checks the liquid level and sludge depth, and looks at the inlet and outlet baffles, the tank walls and the lid. Water may be run through the house to watch how the system handles flow. The drain field is checked for wet spots, odors and signs of surfacing water. Pump chambers, alarms and filters are tested if the system has them.

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 Des Peres, 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.

Before the inspector arrives

Find the tank if you can, move vehicles off the drain field and make sure the inspector can reach the lid. Have records ready and a list of questions. If you are the buyer, ask the seller for permission and records well ahead of time. If the lid is deeply buried, ask whether digging is included or billed separately.

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 Des Peres and Kirkwood, Frontenac, Town and Country is a plus.

Septic inspections in St. Louis County

What inspectors look at closely around Des Peres

Because most mapped soils near Des Peres are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. Des Peres averages about 43 inches of precipitation a year. Mention recent heavy rain to your inspector, since it can change what the drain field shows. Frozen ground in the colder months can limit what an inspector can see, so plan inspections for a home sale early when you can.

Among the mapped soils within about two miles of central Des Peres, the USDA soil survey rates 96% as very limited for septic absorption fields, 4% as somewhat limited and 0% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.

Des Peres averages about 43 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 1 month a year, with January averaging 30°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
