You've been listening to people talking out their asses.

Water acidic enough to affect plumbing would be unsafe to drink.

Actually pinhole leaks caused by corrosive pitting of copper pipes are
most commonly associated alkaline water, not acidic, though the exact
cause has not been determined. See for example

Sounds to me like substandard materials.

I'd look for a galvanic reaction instead of looking for some
mysterious PH inbalance that somehow can't be tasted.
