Pinhole Leaks

Fascinating . Thank you for sharing your research and discovery!

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.

Thank you. Surprisingly these Leaks happened on pipes that have small damage to corrosión protection insulation. This also affects rebar

It is not sufficient for a Master to simply FIX a problem. The Master should understand the Causes of a problem.

I worked for a water utility for 38 years as an electrician and instrumentation technician, certified as a water distribution manager. Also am a moderator at the Mike Holt Code Forum where there would be questions on grounding and copper leaks. I would typically suggest to get the Consumer Confidence Report for the source water and to see if there what the pH is, what if any corrosion control is implemented to comply with the EPA lead and copper rule. our utility implemented corrosion control to comply with the lead and copper rule 1n 1999, by slightly raising the pH from 8.0 to 8.5 and that has proven very effective in follow up testing. Water with a low pH tends to be aggressive and removes the protective film on the inside of copper and lead pipes. I also have the a definitive study "the effects of electrical grounding on pipe integrity and shock hazard (1996) by the American Water Works Research Foundation, where they state its DC current that causes corrosion, but AC current that causes much less corrosion in pipes.

Excellent work, I've been aware of such problems for years and never had a good answer except "grounding", but couldn't make any recommendations.

Scotland Yard would be proud!
