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.

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 Marysville.

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 Marysville, WA

If a home in Marysville uses a septic system, the condition of that system can change what the house is worth. An inspection looks at the tank, the pipes and the drain field so there are no surprises after closing.

Local septic companies that serve Marysville can inspect for a sale, a refinance or simply because you want to know how your system is holding up.

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.

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 Marysville, 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 inspection day

Make the inspector's job easier by locating the tank lids or marking where you think they are, and moving vehicles away from the area. Have a list of questions ready. If you are a buyer, ask the seller for any septic records the Snohomish County health office may have on file.

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 Snohomish County.
