We have a Solitude 369RL, but I would think that this question applies to all products. My grey water 2 always shows 2/3 full even when the drain handles are open. any one have any suggestions or fixes? I'm not sure it hasn't been that way since new. I know it is not full as we are spending 3 months in it and I know it would be backed up inside by now. Thanks in advance for any help.
