Septic Inspection in Walla Walla, WA

A septic inspection tells you whether the system under a Walla Walla 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 Walla Walla and College Place, Milton-Freewater, Waitsburg will explain what their inspection includes and when they can get out.

The checklist an inspector works through

Expect the inspector to locate every component, measure how full the tank is, check inlet and outlet baffles for damage, and watch whether water flows the right way. Many also run water through the house to see how the system responds and walk the drain field for wet spots or odors.

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 Walla Walla 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 a septic inspection report

The report should say where each part of the system is, how big the tank is and what it is made of, how full it was, and the condition of baffles, filter, lids and any pumps. It should describe how the drain field looked and list recommended repairs, with photos where possible.

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 Walla Walla

Because most mapped soils near Walla Walla are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. Walla Walla averages about 27 inches of precipitation a year. Mention recent heavy rain to your inspector, since it can change what the drain field shows. Frozen ground in the colder months can limit what an inspector can see, so plan inspections for a home sale early when you can.

Among the mapped soils within about two miles of central Walla Walla, the USDA soil survey rates 79% as very limited for septic absorption fields, 16% as somewhat limited and 5% as not limited.

Walla Walla averages about 27 inches of precipitation a year, and December is usually the wettest month. Average temperatures stay below freezing for about 2 months a year, with December averaging 30°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
