We have a 2016 Sundance 3700RLB, I recently decided to flush both front&rear black water tanks. As I was flushing the rear tank with the flush system, my wife noticed there was a large amount of water on the rear bathroom floor. Has anyone else experienced this problem? Any ideas of what would cause this? I’m hoping not to have to totally dismantle the rear half of the trailer in order to fix this problem.
