A septic inspection tells a buyer what the seller may not know: whether the tank is sound, whether the baffles are still there, whether the distribution box is level and whether the field takes water. In Gaston County a lot of sales are of houses on systems installed decades ago, and a written inspection before closing is the difference between a $500 check and an $8,000 surprise.
The inspection is done with the tank pumped, because a full tank hides everything. The crew walks the field, runs water, checks the box and writes up what it found in plain language with photos, the kind of report a lender or a buyer's agent accepts.

Inspections and the Gaston County record
Gaston County Environmental Health keeps permit records for systems installed under the state rules, and a copy of the original improvement permit and operation permit shows the tank size, the field layout and the number of bedrooms the system was sized for. Part of a good inspection here is comparing the house today with the permit: a fourth bedroom added over a garage in the 1990s is a system that was never resized. Gaston County lists no point-of-sale inspection among its septic permits and approvals, so it is the buyer's due-diligence contract that makes an inspection happen.
The clay tells its own story. A field that passes a dry-week walk can fail a load test after two days of rain, so the crew notes the weather and the recent use when it writes the report, and says plainly when a second look after rain is worth the money.
Septic Inspection pricing in Gastonia
A standard inspection with pumping runs $250 to $500 in Gaston County, more if the tank has to be dug out. A camera run through the lines adds $100 to $250 and a dye test about the same. Quote first, on the phone, from a description of the house and the system.

Septic Inspection questions, answered
Does the seller or the buyer pay for the inspection?
Usually the buyer, as part of due diligence. Sellers sometimes pump and inspect first so the report is ready and the field is not the reason a deal stalls.
Can you inspect a system with no county record?
Yes. Older systems installed before records were kept are inspected the same way; the report notes that no permit was found.
