Installed a new water heater. The hot and cold lines had corrosion. I tried to clean them up and hoped for the best
. They both have a slow leak. I want to replace them now, but it's not going to be as easy as it should be. The lines are copper flex lines with connectors on the water heater side only. The other side is soldered. Finding an exact replacement might be difficult. What would be the best method of repairing this? I have 3 ideas in my head.
