During a home inspection, what kind of plumbing issue is considered a major red flag?

Signs of leaks or water stains are often regarded as a major red flag during a home inspection because they can indicate underlying plumbing issues that may lead to more significant problems if left unaddressed. Leaks can cause water damage, promote mold growth, and compromise the structural integrity of a home. Identifying visible signs of leaks or stains offers insight into the plumbing system's current condition and the potential for ongoing issues, making it essential for home inspectors to emphasize this observation during their assessment.

While rusty pipes, low water pressure, and old fixtures can suggest plumbing concerns, they may not always indicate immediate or severe problems. Rusty pipes could suggest corrosion but might not be critical in terms of functionality, depending on the material and condition. Low water pressure can be caused by various factors, some of which could be easily remedied, and old fixtures may not necessarily be problematic, as they can often still function adequately. However, the presence of leaks or significant water stains typically signifies a more urgent situation that requires further investigation and potentially costly repairs.
