Good morning! Collect permit records, previous owner documents, tank location clues, vacancy dates, planned occupancy, and notes from the brief plumbing tests. A request for Septic Tank Cleaning in Spartanburg should tell Rock Solid Septic & Excavation that the system has been idle, so the visit is not mistaken for routine service at an occupied home. You should also have indoor leaks and running toilets corrected before judging system performance. If the tank, piping, or drainfield condition cannot be verified during cleaning, obtain a clear list of limits and follow-up work.
