Spontaneous Leaks in Copper Pipes

[David C.]

This has now happened 3 times in my primary residence.

I find a puddle on my basement floor, look up and a copper pipe is dripping very slowly from the middle of a length of pipe, its not at a joint, and the rest of the pipe is dry. Just a spontaneous pinhole leak.

So far I've been lucky, this keeps happening in the basement, but now these last two are only a few weeks apart.

What would cause my copper pipes to corrode spring spontaneous leaks? This last one was in a part of the ceiling with a drop-ceiling that has not been touched for months. The other 2 leaks were in an 'unfinished room' where I figured I probably hit them with something I was moving. But this last one is clearly an undisturbed pipe spontaneously leaking.

Should I not be drinking my water? Should I be getting the whole house re-done with PEX? Home was built around 1989.

Thanks for any ideas.
