The way her water tasted it must have been more conductive than copper!
BTW, nonconductive water is *extremely* hard to generate--it starts to
become conductive just with contact with air, container, etc. I did a
little investigation into pure water for semiconductor fab back in 1960.

I have no direct experience of copper pipes being pinholed by lightning. I
wouldn't expect lightning to be a problem with copper pipes in concrete, as
concrete is a good enough conductor that a long bar of it is sometimes used
for making a ground in light sandy soil (Ufer ground if my memory serves
me). Some type of electrolytic action between concrete & copper is more
likely the cause of copper-pipe-in-concrete going bad.
Getting a bit off-topic...
