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.

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.

Does Molalla 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 Clackamas 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 System Inspections for Molalla Homes

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

Good times to schedule an inspection

The most common reason people in Molalla call for an inspection is a home sale. Other good times include before a renovation that adds water use and after heavy flooding. It also helps when you notice slow drains or odors, or when you move into a home with no records for the system. Regular inspections help you catch small problems before they turn into drain field replacements.

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.

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.

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 Molalla

Because most mapped soils near Molalla are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. With about 62 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.
