Robert: Pin hole leaks in copper piping is not a new phenomenon even though you may not of heard or experienced it before.
I have been a Plumbing Contractor for almost 50 years, and have spent considerable time (28years) trying to cut through the fiction and fact that is generally associated with the reasoning for this type of costly and annoying pipe failure.
Below are some excerpts of articles that I have printed on the subject..it is not a solicitation for you to purchase a product that we manufacture to control this corrosion process.
It is an attempt to explain in laymans' terms the dynamics that are involved in the process that causes the pipe to fail.
The copper industry has lost a great deal of market share of piping through no fault of their own. The cause of pin hole leaks is not the result of an inferior quality copper pipe. The cause of the failure due to pin hole leaks is not the result of attack by municipal water supplies that conform to the "Federal Clean Water Act" mandates.
The problem lies with electrical potential differences within the piping system. These differences are so small that they require the use of a milivolt meter to detect. A milivolt is 1/1000th of a volt.
The water that is supplied to your home is more than likely good wholesome water. It has been treated by the water department to remove unwanted
things and chlorine to keep it safe from contamination en route to your home.
The water, because of desolved minerals and gasses has the ability to conduct an eletrical charge. This ability to conduct electrically makes the water an "Electrolyte". An electrolyte is simply a term used to describe a condition whereby a liquid has electrical current carrying capacity.
The engine that drives the corrosion process (Electrolysis") is this miniscule amount of electrical energy mentioned earlier. If this unwanted voltage could be isolated or cancelled out, there would be no corrosion...and therefore no pin hole leak failures.
That is more easily said than done however.
The corrosion process that causes the pin hole leak is taking place inside the piping..24 hours a day year in and year out until it finally eats a hole through the pipe wall and starts to leak.
The process that is responsible for the pin hole phenomenon has a rather
pretentious name: "Electrochemical Decomposition". It is also referred to as "Electrolysis". Without using elaborate technical terms, I will try to explain very briefly what happens inside your piping system...how it happens...and why it happens. I will also provide you with some answers on what can be done to deal with the results of electrolysis.
There are three things needed to create a pin hole in a pipe...........
1.) A metallic pipe (Copper) with a liquid (Water) flowing through it.
2.) An "Electrolyte", in this case the water is the electrolyte. An electrolyte is simply a liquid that has the ability to conduct an electrical charge.
3.) And a very very small amount of DC electrical voltage. The electrical energy
Where ever there is a disparity in electrical potential within your piping system,
