Start with the system and service history
Share the system type if known, property address, previous inspection or pumping report and any observed problem. Ask whether the company handles that system’s tanks, pumps, treatment components and drainfield. Avoid entering or opening the system yourself; arrange access and identification with the service professional.
- System type and available plan
- Last inspection and pumping records
- Observed issue and timing
- Known access and electrical components
Clarify inspection, pumping and diagnosis
Ask what is examined and recorded during the visit and whether pumping is included, optional or priced separately. EPA describes inspection and pumping as different maintenance activities and notes that service needs depend on the system and household. Ask the professional to explain the findings supporting a recommendation rather than assuming one fixed interval fits every property.
Authorize repairs as a separate scope
Confirm applicable local authorization, permits and disposal arrangements with the responsible authority and contractor. Ask how access, excavation, locating lids and ground reinstatement are charged. Get a written recommendation and estimate before additional repairs. A routine pump-out does not by itself establish that every system component is working correctly.
Keep a report that supports the next decision
Request the tank condition, findings, work completed and further recommendations in the service record. Ask who to contact about an unresolved problem and whether a maintenance agreement has defined visits, included work and extra charges. Retain reports and approved repair documents for the next professional rather than relying on memory.
