my son was replacing the shower spicket in the bathroom and he couldn‘t get it twisted off the copper pipe and twisted too hard and split the copper pipe for the bathtub so when you pull the knob to use the shower it spews water inside the wall where the split is. there is no access panel to get to the plumbing so i was thinking of unsweating the joint and replacing the the piece of copper tube. is this possible or should i cut a hole and go in from the other side. its all copper tubing and fittings
I can't imagine you'll be able to get to it w/o opening the wall. Hopefully it's just sheet-rock on the other side, and easy to patch paint.
it may be stainless steel
