Pin holes in hot water pipe
Posted by Russ Romond on September 15, 2002 at 22:30:11:
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
Russ Romond
