This is kind of a change order a thing from when we were here before the fireplace was getting raised and I needed to disconnect and remove it so I wanna head and removed the flex supply and capped off the half inch black iron. Secondly in the primary kitchen we stubbed a half inch cold water line out of the wall above the gas stove for a future pot filler Tested both the water and gas after turning back on and had no problems and no leaks
