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.

Who pays for a septic inspection during a sale?

It depends on your contract and local practice. Buyers often pay for their own inspection, while some sellers order one before listing. Your real estate agent can tell you what is typical in Moses Lake.

How often should I inspect my septic system?

Septic System Inspections for Moses Lake Homes

A septic inspection tells you whether the system under a Moses Lake 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 Moses Lake and Warden, Ephrata will explain what their inspection includes and when they can get out.

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.

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 Moses Lake 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.

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 Grant County.

Inspections for buyers and sellers near Moses Lake

Real estate deals in Moses Lake and nearby towns such as Warden, Ephrata often include a septic inspection as part of due diligence. Some lenders and counties have their own requirements, so check with your agent early. Scheduling the inspection soon after an offer is accepted leaves time to handle any repairs.

What inspectors look at closely around Moses Lake

Because most mapped soils near Moses Lake are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. Moses Lake gets about 10 inches of precipitation a year, so wet spots over the drain field stand out and deserve a closer look. Frozen ground in the colder months can limit what an inspector can see, so plan inspections for a home sale early when you can.

Local conditions in Moses Lake that affect septic inspection

Among the mapped soils within about two miles of central Moses Lake, the USDA soil survey rates 61% as very limited for septic absorption fields, 3% as somewhat limited and 35% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.

Moses Lake averages about 10 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 31°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
