An Overlooked Pre-Purchase Home Inspection

When buying a home, most people know to schedule a general inspection and even a sewer lateral inspection, but many overlook another crucial component: the drain system beneath the house.

Older homes, especially those built before the 1970s, often have cast iron drain-waste-vent (DWV) systems, and even though these materials were standard for decades, time has not been kind to them. Cast iron pipes are prone to internal corrosion and buildup, which can cause leaks, blockages and even system failures. When these problems surface, they can result in backups or flooding with contaminated water.

The best way to prevent this is to have the home’s drain system inspected before closing the deal. A plumber can perform a camera inspection to assess the condition of the pipes and identify any hidden damage. Knowing the drain system’s condition upfront will allow you to make informed decisions, negotiate repairs or budget for future replacements.
