Ever see green-gray stuff on your pipes and wonder what it is? Well, it’s due to a bi-metallic reaction, also called electrolysis. If 2 different types of metal are in contact with each other in a plumbing system, chances are corrosion and damage are occurring. It’s also common for us to see it in an inspection where metal pipe hangers are supporting plumbing. Galvanized piping is especially susceptible to damage and often needs replacement. Eventually leaks can develop and plumbing repairs will become necessary.
Our recommendation is to grab a flashlight and look at the pipes, or better yet call a plumber to check it out. If repairs are needed, it will be cheaper now then later after they start leaking!
