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.

Inspection options to ask about

Common options include a basic flow test or a full inspection with the tank opened. Some inspectors pump during the visit so the tank can be seen empty, run a camera through the lines, or probe the drain field. Your inspector can recommend the right mix for the property. the Thurston County health department may also have its own requirements for inspections tied to a sale or a permit.

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.

Reading your inspection report

Look for three things: what was inspected, what was found, and what is recommended. Pay attention to notes about parts of the system that could not be reached, since those are unknowns. Ask the inspector to explain any term you do not understand and to rank repairs by urgency. If you are buying, share the report with your agent so it can be part of the negotiation.

How to prepare for an inspection

Gather any septic permits, past pumping receipts and repair records. Mark the tank location if you know it and make sure the area is clear. If you are selling, avoid pumping right before the inspection unless the inspector asks for it, since a freshly pumped tank can hide how the system has been performing. Make sure water is on in the house so the inspector can run fixtures.

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 Thurston County.
