Plumber, plumbing, pipe repair, leak repair. Copper Line Repair. Upon arrival customer stated that their hallway bathroom cold side 1/2” copper line has been leaking at the 90 degree elbow in the basement. Upon inspection I found that the 1/2” copper supply line was leaking from the fitting due to poor solder work. Removed drywall in the basement bathroom wall, removed the bad elbow, cleaned up the copper pipe, soldered new elbow in. Checked for leaks. OK. Homeowner will repair the drywall.
