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.

Is a home inspection enough for a septic system?

Usually not. General home inspectors often do only a quick look at the septic system. A septic company opens the tank and evaluates the drain field, which gives a much more complete picture.

Does Yelm 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 Thurston 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 Yelm Homes

Request a call and a septic company that inspects systems in Yelm and Rainier, Lacey, DuPont 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.

Inspections for buyers and sellers

Buyers use an inspection to learn what they are taking on. Sellers use one to fix problems before listing or to show buyers the system is sound. In either case, schedule early in the process so there is time to pump, make repairs or negotiate. Waiting until the last week before closing leaves little room if the inspector finds a problem.

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 the property ready

Clear access to the tank lid and drain field, unlock gates and keep pets inside. Let the inspector know about any past backups, alarms or repairs. If the home is vacant, ask whether water should be run ahead of time. the Thurston County health department may have records for the system that the inspector can use, so it helps to request them early.

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 Thurston County.
