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.

Does Sherwood 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 Washington 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 Inspection in Sherwood, OR

A septic inspection tells you whether the system under a Sherwood property is working, what shape the tank and drain field are in, and what repairs might be coming. It is one of the most useful reports you can have before buying or selling a home that is not on city sewer.

Request a call and a septic company that inspects systems in Sherwood and King City, Tualatin, Durham will explain what their inspection includes and when they can get out.

Inside a septic inspection

Inspectors look at the system from the house to the drain field. They confirm where the main line leaves the house, open the tank to check its condition and levels, and inspect the baffles and any effluent filter. Outside, they walk the drain field and look for soggy ground, lush grass stripes or odors. Some inspections add a camera run through the lines or a hydraulic load test that sends a measured amount of water through the system.

Quick checks versus complete inspections

Some inspections only confirm that drains run and nothing is obviously wrong. A complete inspection opens and measures the tank, examines the baffles and filter, checks pumps and alarms, and evaluates the drain field. When money is on the line, such as a home purchase, the complete version is usually worth it.

Good times to schedule an inspection

The most common reason people in Sherwood 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.

Choosing a septic inspector

Look for an inspector who explains the process clearly, provides a detailed written report and is not rushing to sell you repairs. It is reasonable to ask whether the same company performs repairs and how they handle that. Experience with the types of systems common around Sherwood and King City, Tualatin, Durham is a plus.
