During a recent Pleasant Hill home inspection, the inspector discovered what you’d expect to see coming out of a volcano – lava.
This is the top of a water heater tank that’s heavily corroded and what happens when copper pipe is connected incorrectly to steel pipe.
Technical talk: this is called galvanic corrosion and refers to corrosion that occurs when two different metals are in electrical contact with an electrolyte.
Inspector talk: copper and steel are dissimilar metals and if not insulated from each other, corrosion can take place.
With a corroded pipe and water seepage – the photo made for a lava flow of sorts on top of the water heater.
