I seem to have hit a small snag. As I mentioned above, I kinked the existing copper line while reinstalling the washer last night. It was leaking. I bought a new PVC line today (avoiding the kinking issue in the future) and went to install. Unfortunately it seems the copper line is welded into the shut off valve under the sink instead of having a threaded end. Is the best solution to just buy another shut off valve, turn off the water to the house and install that or should I try to fit some sort of threaded adapter onto the existing copper tubing?
