How do you know if it's solid cable or not? We have a 2013 Forest River 337FB and when we tried to attach the drain hose to empty the tanks today, we found out the hard way that our waste water valve was leaking. EWWW! (I'm thanking the good Lord for my hubby who was there to handle that mess.)
The rod looks like it does not go all the way in at the panel.
Not sure what our next step should be. I'm starting to realize the value of hotels.
