Hammering in new carpet tack strip and punctured a water line! Help.

[MichaelD]

Last night I was finishing a wall repair from where a pipe had corroded. Last step was nailing in a new tack strip to the concrete floor to hold the carpet.

My fourth nail hit a pipe that was burried in a 1/16th of an inch of concrete and run along the wall.

I've begun excavations and it is some sort of manifold. What am I looking at and how do I repair this? (See photo)

Apologies to the color blind, I didn't know how else to show this.

Blue is 3/4
Orange 1/2 runs to a sink
Yellow 1/2 is what I hit. It runs 6" along the wall and down into the slab.
Red 1/2 runs down into slab
Teal is 3/4 out or in to slab
Purple is 1/2 into slab
Green is 1/2 into slab

Being all copper makes that much easier. If you do not know how sweat copper pipe, you'll need a plumber.

If you're good with a torch, you can cut the yellow pipe about half way down. Cut the pipe somewhere under the slab. You can sweat new pipe and use new fittings. Not sure I would use Sharkbite fittings. Sharkbite has a tape that you wrap around the fitting when in contact with the ground and dirt.

Another way,
Unsweat or cut out the red to the yellow, then the tee to the yellow. Remove the tee. If you're good and not get the blue tee too hot you may be able to leave it. If the old solder got soft, remove it also. Essentially do not reuse old fittings if possible.

More digging is needed to get to the pipes. Another option is cut it all out, get the pipe further inside the wall and deeper under the slab especially along the wall. To match up the pipes going under the slab, some 45 degree fittings would be needed. To get all pipes matched up, the 90 degree elbows would be the last fitting to connect the pipes.

Clean, cut, coupling. You can rent a pro press if you want. But those connections should be brazed.
