Inspection before sale
EPA tells homebuyers to have a septic system inspected by a service professional before purchase. Whether that inspection is required is a state or local rule — not a federal one. We do not invent your county’s requirement.
EPA: inspect before you buy
EPA’s New Homebuyer’s Brochure and Guide to Septic Systems (page last updated 24 February 2026) exists because a septic system is expensive to repair or replace. The August 2017 guide (EPA-832-F-17-010) says: have the system inspected before you purchase. Inspections may be required by your local or state government or by your mortgage lender.
On the same guide, EPA lists what the inspector will check: pumping and maintenance records; age of the system; sludge and scum thickness; signs of leakage (low water in the tank); signs of backup (staining above the outlet pipe); integrity of the tank, inlet, and outlet pipes; the drainfield for standing water; the distribution box for equal flow; and records for local compliance.
EPA’s frequent questions add: open all tanks, evaluate any effluent filter, check electrical connections and pumps, possibly camera pipes, and possibly excavate parts of the drainfield. That page also states: “In many states, a septic system must be inspected with the transfer of real estate.” EPA does not name which states. Contact your local health or environmental department.
Pumping versus inspecting versus repairing
- Pump / haul
- A licensed or registered septage hauler removes sludge and scum and takes it to a permitted disposal site. Ohio: a hauler may also evaluate the tank they are pumping — that is still not a full real-estate inspection in Ohio’s registration scheme.
- Inspect (including point of sale)
- A professional opens tanks, looks at the drainfield, and writes a report. In Ohio, point-of-sale evaluation is listed under the service provider registration (ODH Information for Contractors, retrieved 29 August 2026). In Wisconsin, Shawano County prints POWTS maintainers on a separate “No Pumping” list. Clallam County, Washington prints a separate O&M inspector list.
- Repair / install
- Replacing a tank or drainfield usually requires an installer permit. A pump-out does not repair a failed drainfield. EPA: if a drainfield is more than 25 to 30 years old, the biomat can thicken and the field may no longer accept wastewater.
We will not invent your closing requirement
Some counties require a pump-out near closing. Some require a full inspection. Some require neither. If we have not fetched that county’s ordinance, this site will not guess. Ask the local health department, the SEO, or the buyer’s lender. EPA: get the “as-built” drawing from those same offices.
How to find an inspector on this site
- Shawano County, WI — pumpers and POWTS maintainers, 19 May 2026.
- Clallam County, WA — separate O&M inspector list.
- York County, PA — haulers only. Ask which firms also inspect; we did not invent that field.
- Geauga County, OH — registered pumpers. Ask GPH for the current service-provider list for a point-of-sale inspection.
