Can a septic system fail an inspection?

Inspectors usually describe condition rather than giving a simple pass or fail, but a report can show a system is not working or needs major repair. Ask what standard the inspector uses and what the findings mean for your situation.

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.

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

Rules differ by county and state. Some areas require an inspection or certification when a home changes hands and others do not. Check with the Lewis and Clark County health department to confirm what applies.

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 Inspection in Helena, MT

Most septic problems are cheaper to fix when they are found early. A professional inspection in Helena 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 Lewis and Clark County can give you a clear written picture of your system.

What the inspector checks

Expect the inspector to look at four main things. First is the tank's structure and water level, then the inlet and outlet baffles. Next come any pumps, floats and alarms, and finally how well the drain field is absorbing water. On older Helena homes they also look for signs that the system was changed or repaired without records. The goal is a clear picture of whether the system works today and what it may need soon.

Choosing the right kind of inspection

A walk-through inspection is fine as a routine check on a system you know well. For a home sale, a refinance or a system you know nothing about, choose a full inspection that opens the tank and looks at the drain field. Some lenders and counties specify which type they will accept.

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 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 Lewis and Clark County.

Septic inspections in Lewis and Clark County

What inspectors look at closely around Helena

Because most mapped soils near Helena are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. Helena averages about 22 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.

Local conditions in Helena that affect septic inspection

Among the mapped soils within about two miles of central Helena, the USDA soil survey rates 82% as very limited for septic absorption fields, 18% 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.

Helena averages about 22 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 5 months a year, with December averaging 18°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
