We have used our Impact 311 for two trips now. The only real thing I've found so far, is the black and/or gray water tanks seem to leak fluid into the dump lines while being used. Each time I've gone to open the pipe to hook the drain hose to it, I get grey water (hopefully-not black) come flushing out. Like two gallons worth. Needless to say, this isn't making me happy. Has anyone had this happen, and if so how can I adjust this so the valves close completely?
