Electrolysis can be a greater problem if there is an electrical ground wire connected to the hot water piping. It can even destroy a water heater in a matter of months, as one of my customers discovered one morning.

: Terry,
: I'm noticing a series of pin holes developing along the bottom edge of my hot water pipe. You see a droplet of water & green oxidation on the pipe. For now the drips are minor & could be repaired by replacing the section of pipe.
: My question is what will fix the problem "long term".
: The pipe in question is an original, circa 1953, but a hot water heater was installed about 5 years ago. I thought it might be a grounding problem, but thought electrolysis was caused by two dissimilar metals? Maybe in the water supply? Why only this one section of pipe?
: Any ideas would be appreciated.
: Thanks
