I have a theory about...

I've replaced a number of those corrugated flexible copper pipes used to
connect the hot and cold on water heaters, and have noticed that often
the leak will be in a pit hole very close to the end where they hook on
to the nipple of the water heater or coming from the house piping.

My theory is that the plastic bushing used at the end of the corrugated
pipe stops electric flow thru the pipe system, and so the charge jumps
the gap by passing thru the water - then creates a pit where it
re-enters the copper piping.

Baloney, or brilliant?

Check the PH of your water.

Replace the corrugated copper lines with corrugated STAINLESS STEEL
lines.
No galvanic effect and no dielectric union needed.
