Slab Leak

My plumber found a slab leak under the concrete floor in our guest bath room/bedroom area. There was a pinhole in the copper pipe. The pipe has a red tint to it in the area of the pinhole. The plumber says maybe it is from electrolysis. Maybe there is an electrical current or ground problem. There are several people in our neighborhood of about 50 homes that have had slab leaks in the past 5 years or so. This is our 4th leak in 4 years. We are in Ft Worth, TX and have clay soil. Also my brass fittings corrode. The chrome fittings do not. If someone wants a photo of the piece of pipe with the pinhole let me know & I'll post one. I'm not happy waiting for leak #5. What should we do?

Replumb with pex in your attic? That's a question, I don't know if that would work for you but its something to consider.

It is something to consider.

Asking why copper developes pinholes is bound to start a great debate.
I'm all ears There's a neighborhood near me that was built in '92. Copper leaks appear under the slaps now and then. don't know why but pays good though.

I would not recomend running Pex in the attic, or any other water lines for that matter. Even though you are in a warmer climate, Ft. Worth does see its share of below freezing temps. Definitely dont want your lines to freeze and rupture.

As for the pin hole issue, there are a number of things that can contribute to this. The Most common cause I see is improper installation. In your situation I would lean more towards the environment and the quality of water in the line.
