A standard home inspection inspects components that are visible and readily accessible. We are limited to running water for several minutes and looking for backups or leaks, but many times issues in the drain piping may not be uncovered through these means. Sewage drain lines are typically hidden and located below ground, and so issues are typically outside the scope of a home inspection. We do offer a Sewer Lateral Pipe Scope Inspection though which can be purchased as an add-on service. This service places a camera inside the sewer lateral which helps to uncover hidden issues such as crushed or cracked pipes, blockages, problematic piping, pipe offsets, low-spots, etc. These issues can be very expensive to correct. This inspection only inspects the larger sewer lateral pipes extending from the home to the private septic system or public sewer line, not any waste arms, and is highly encouraged prior to any home purchase.
