"Pin hole" corrosion of inner water pipes
"Pin hole" corrosion of inner water pipes
(OP)
Who can explane, why the inner water pipes in building became "pin-holed"?
May it be due the AC electrical current flow on this pipes or exist another reasons?
What must be done in this situation?
Thanks in advance.

Stray electrical currents can also have an effect on corrosion, but not normally in residential applications. More limited to cathodically protected underground systems.

I highly recommend you review the book entitled "Internal Corrosion of Water Distribution Systems" by AWWA Research Foundation, 1996; this is an EXCELLENT source of information whether your problem is copper, cast iron, ... This reference has photos of the various examples, history, causes, and preventive methods / recommendations. Check out the book - you won't regret it. Also, there are several paperback AWWA Research Foundation reports on more specialized topics.
