During a recent 4-point inspection, we came across a common but serious issue—green and white corrosion on a copper pipe exiting a water heater through the wall. At first glance, it might just look like a bit of discoloration. But a closer inspection revealed an active leak and moisture damage inside the wall.
The Clues:
When we touched the area with a moisture meter, the reading jumped to 41%—a strong indicator of water intrusion. The wall was discolored, and the corrosion had clearly been developing for some time. This wasn’t just a plumbing problem; it was a sign of ongoing water damage that could eventually lead to mold or structural issues if left unaddressed.
The Bigger Picture:
The water heater in this home was manufactured in 2003. And here’s the kicker—most insurance companies will not insure homes with water heaters older than 2005. That means this homeowner is facing two big red flags on an inspection report:
- An active leak
- An outdated water heater
What We Recommended:
Rather than patching the leak and keeping an aging appliance in service, we advised the homeowner to consider replacing the water heater entirely. Not only does this solve the immediate problem, it also makes it easier to secure or maintain insurance coverage.
Why This Matters for Your Inspection:
If you’re buying or insuring a home in Florida, this kind of issue can delay closing or cause policy denial. During a 4-point inspection, we’re required to report the condition of the water heater, plumbing system, and any signs of leakage or deterioration. What might look like a small drip to a homeowner could become a major roadblock in a real estate deal.
Takeaway:
Don’t ignore corrosion or assume that older systems can keep running indefinitely. Water heaters have a lifespan, and insurance companies are drawing the line tighter every year. If you’re unsure about the condition of your plumbing or water heater, give us a call—we’ll help you get ahead of the problem before it becomes a bigger one.
