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.

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 Lewis County health department may also have its own requirements for inspections tied to a sale or a permit.

When an inspection pays for itself

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

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.

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 Lewis 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 Lewis County.
