Septic System Inspections for Arlington Homes

Most septic problems are cheaper to fix when they are found early. A professional inspection in Arlington 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 Snohomish 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 Arlington 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.

When an inspection pays for itself

An inspection is most valuable before money changes hands: when buying, selling or refinancing a home in Arlington. 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 a useful report includes

A useful report gives you facts you can act on: measurements of scum and sludge, the condition of each part, a sketch or photos of where things are, and clear recommendations. If repairs are listed, ask the inspector which ones are urgent and which can wait.

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 Snohomish County health department may have records for the system that the inspector can use, so it helps to request them early.

Questions to ask a septic inspector

Ask what their inspection includes, whether the tank will be opened, and whether pumping is part of it. Ask if they probe or test the drain field, how long the inspection takes and when you will get the report. Confirm licensing or certification required where you live and ask for a sample report so you know what to expect.

What inspectors look at closely around Arlington

Because most mapped soils near Arlington are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. With about 72 inches of precipitation a year, an inspection after a dry spell can look better than the system really is. Ask how recent rain affects the results.

Local conditions in Arlington that affect septic inspection

Among the mapped soils within about two miles of central Arlington, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is moderately well drained.

Septic Inspection questions in Arlington

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 Arlington.
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.
