Upon arrival customer had a leak on the hot side of the water heater on the half in line at the 90 going into the dry wall. We informed the customer in the steps that would needed to be taken to resolve the issue. Customer agreed. We proceeded to open a small portion of drywall that was damaged by the leak. Once the pipe was exposed we then cut out the leaking section and soldered on a new section of pipe. We then tested the pipe for leaks and there are no more leaks. Successful repair.
