What a well inspection covers
EPA advises periodically inspecting the exposed parts of the well for a cracked or corroded casing, a broken or missing cap, and settling or cracked surface seals.
What gets checked
The Iowa DNR private well program lists the inspection points an owner can see: the well cap and vent screen, wiring conduit, casing height and condition, grading and the pressure tank.
Iowa DNR says the finished casing should be at least 1 foot above the ground and show no cracks or damage.
Iowa's existing private well inspection checklist covers setbacks from contamination sources, the casing, the well cap and vent, and the pitless connection.
The Virginia Cooperative Extension WellCheck form has the contractor record the pressure tank pre-charge, pump cut-in and cut-out pressures, valves and the pressure switch.
The Minnesota Department of Health says wells do not last forever and that an old well should be inspected by a licensed well contractor.
For a home sale in Tennessee, the state has no sampling rule, so ask the lender which items to test and use a certified lab.
