I have a 2010 Cardinal. I am on vacation In the south and my grey tank will not drain. On my sensors the galley shows empty but the grey is full. I have the waste water valve pulled and nothing will come out. Is there a bypass somewhere? What am I doing wrong?
So you have one for the kitchen and one for the bathroom, plus a black water. That makes 3 handles. Are you pulling both grey water valves open? One should empty just the kitchen and the other the bathroom grey water.
Ok so the left valve is the bathroom grey the middle valve is the black and the right valve is the kitchen grey. I have never just wanted to dump just the grey. I will have to relabel the valves. Thanks for the replies. I am sure I will have more as we are starting to travel long distance for vacation.
