Find the Approved Layout
Use the county record to identify the drain field, its extent and later repairs. Compare the plan with landscaping, paving, fences and new structures. Buried components may need locating before their condition or location can be confirmed.
Record Symptoms and Weather
Note odors, wet ground, slow drains and how long symptoms last after rain. A flooded week and an unusually busy household create different loads. Observations during one dry visit cannot prove year-round field performance.
Check Distribution Where Accessible
Accessible distribution boxes, outlets, inspection points and dosing controls can reveal uneven delivery or high water. Confirm whether camera work or exposing components is included. Some buried conditions cannot be seen without additional investigation.
Consider Soil and Seasonal High Water
A private inspection is different from the qualified site evaluation needed for a construction or repair application. A replacement design may need soil and seasonal-water information even when the existing field's location is known.
Use the Findings for the Decision
Connect each concern with a recommended action: maintenance, component repair, further evaluation or replacement planning. For property purchases, define the inspection scope early and retain the written findings with the system record.
