Visual inspection - Requires Pumped Tank -A septic system inspection involves evaluating the condition and functionality of the entire system, including the tank, distribution lines, and drain field. Inspectors typically locate and uncover the septic tank, check its structural integrity, measure sludge and scum levels, and ensure that waste is flowing properly from the home. They may also inspect for leaks, signs of backup, and proper drainage in the leach field. Some inspections include a dye test or camera inspection to detect hidden issues. This process helps identify current or potential problems, ensuring the system is working efficiently and up to code.
