Hi guys,
I've got an under-slab leak weeping up from one three cold supply pipes. See photo, it's bent, curved mess of soft copper coming up out of the slab. It is the 3/4 line in the center of the photo that's the culprit. I chipped down a little bit to see if I'd get lucky.
My plan was to cut that line and cap it and restore water to see where that goes. I'm hoping I can just feed some 1/2" PEX in there. If you look at the main coming in on the far right, they fed PEX into that line before I bought the house. I want to re-do this whole set-up as that shut off valve doesn't work (they fouled it with over-soldering). Can I un-sweat that main shut-off without damaging the PEX using a wet rag or something? It's only 4" away. Any suggestions on temporary fittings for re-doing this while at the same time isolating the leaker? Is sweating/un-sweating the fastest, easiest way? Any recommendations welcome, thanks
