Pinhole Leaks

Electrical safety is our key concern and I'm always looking out for information that will help keep the industry safe. I wanted to pass along to you an amazing document on Pinhole Leaks, prepared by Gary R. Gabriel, PE. I hope you find it has value.

The point of this paper is to offer design strategy to reduce the risk of pinhole piping leaks. In practice, once the pinhole leaks show up, it is too late for design changes to do any good. By then, the only answer is to replace the entire piping system. Often a failed copper or steel piping system is replaced with plastic pipe. In general, prevailing opinions in the industry (Google it) blame pinhole leaks on other things. This paper offers a contrast in opinion, showing correlation (as well as the foundational science), between the presence of DC voltage on the piping and the formation of pinhole leaks. Gary R.

  • I've seen this corrosion condition on numerous homes - including my own. All corrosion is electrical based..but what is the exact cause.. is it sometimes ph? or sometimes an impressed current from something nearby? Is anyone aware of any actual testing that has been done on homes/businesses affected? I'd love to read them.
