Pinholes may also occur due to phosphate inhibitors that the utility companies use to try and keep the solids in solution. It is not done much any more, but a few years ago it was done and it started a corrosion that cannot be stopped. That is why you find pinholes in geographically concentrated areas. No one will admit to it yet, but lawsuits have been filed, I guess we will just have to wait and see what the courts say.
