CarWin … since this guy is new to the MOC with no info as to if it is a new or used unit … lotsa possibilities come to mind. Dealership tech flipped the valves for some odd reason before delivery … owner flipped the valves out of curiosity … family member or friend experimenting with all the gizmos in the convenience center. He said he had hot water coming out the valve … I interpreted it to be the relief valve.
