What a professional inspection includes
A professional septic inspection usually looks at the main parts that affect how the system works and whether it needs service. The inspector checks the tank, baffles, drain field, and any pump or alarms, then compares what they find with your records.
- Tank: condition, sludge, scum, and signs of leaks or damage
- Baffles: whether they are in place and working as intended
- Drain field: signs of backup, saturation, or other trouble
- Pump and alarms: operation, alerts, and visible issues

Your own walk-around
You can check the yard and the easy-to-see parts of the system yourself, but that does not replace a professional inspection. A quick walk-around can help you notice changes early and decide when to call for help.
- Lids: look for damage, shifting, or lids that seem out of place
- Wet spots: notice soggy ground, standing water, or strong odors
- Drains: watch for slow drains or backups inside the home
If you want a simple place to track what you notice, use the maintenance log template.
What can fail an inspection
Inspections often uncover common problems like damaged parts, signs of backup, wet areas near the drain field, or missing records. In many cases, these are the same warning signs that show up before a bigger problem.
- Common problems: backups, odors, standing water, damaged components, or evidence the system has not been cared for

How often to inspect
EPA recommends a professional inspection at least every 3 years. If your system has pumps, float switches, or other mechanical parts, EPA says it should generally be inspected once a year.

This is not an inspection and not advice from a licensed septic professional. Pump-out timing depends on the tank, the household, and local rules. Check with your local health department.
