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.

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 Antioch 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 Contra Costa 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 Antioch, CA

A septic inspection tells you whether the system under a Antioch 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 Antioch and Brentwood, Oakley, Pittsburg 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.

Visual inspections and full inspections

A visual inspection is a quick check of how the system seems to be working, often by running water and looking for problems. A full inspection goes further: the tank is opened, levels are measured and the drain field is evaluated. For a home purchase in Antioch, a full inspection is usually the better choice because it finds problems a quick look can miss. Ask the company which type they are quoting before you book.

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 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.

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 Contra Costa County.
