Brief background and scope – I have installed a new cast iron tub, valves, shower head, toilet and floor tile in my wife’s bathroom. I also tore out the old surround and replaced the area (tub to ceiling) with cement board and 3 1/2″ square ceramic field tile and a somewhat expensive, upper row of 3 1/2″ x 7″ decorative tile. I, of course, tested the new copper plumbing before hanging the board and tile.
Problem – After setting all the tile except for the bottom row, I discovered that while attaching support boards on which to hang the starter row, I had punctured (pinhole size) a vertical section of the cold supply pipe (section about 8″ long, with a slip joint on one end and a T on the other.) I now have a completely tiled and grouted surround, except for a 10″ square area where I sawed out the cement board and previously set tile. The damaged pipe and joints are exposed, barely.
Question – I don’t have space to use a mini tube cutter (the punctured, vertical section of pipe is about 1″ from a stud and resides in an exterior, rock veneer wall.) Can I “unsweat” this damaged section and resolder with new joints? Alternatively, is there some other way to repair the hole?
She’s ready to shower and I’m ready to leave the country, but not quite yet mentally prepared to tear out the entire wall section.
